Answer:

4x + 2(x – 3) = 4x + 2x – 11

4x + 2x - 6 = 4x + 2x - 11

6x - 6 = 6x - 11

-6 = -11

There is no solution because -6 does NOT equal -11

Answer:

0 solution

Step-by-step explanation:

4x + 2(x – 3) = 4x + 2x – 11

Solve the parentheses:

4x + 2x - 5 = 4x + 2x - 11

Subtract 2x from both sides:

4x - 5 = 4x - 11

From what you can already see that those two expressions does not equal to each other. Let’s continue solving to confirm:

(Subtract 4x on both sides)

-5 = -11

Answer: A: 4.5 hours

B: No, she won't catch up.

C: 21 miles/hour

Step-by-step explanation (SHOULD READ):

Hello! I hope this will help:

Hector = H

Wanda = W

------------------------------------------------------------------------------

Distance of race = 42miles

[tex]V_{H} = 12miles/hour\\D_{H} = 42miles-18miles=24miles\\V_{W} = 16miles/hour\\D_{W} = 42 miles[/tex]

Vh = Velocity of Hector

Dh = Hector's distance to travel

Vw = Velocity of Wanda

Dw = Wanda's distance to travel

----------------------------------------------------------------------------

Now, let's solve these exercises!

Write and solve an equation to find when Wanda will catch up to Hector.

The key words are the bolded words!

What do we have to find?

When Wanda..... Here we can see one thing: time

The word when indicates that we gotta find t (time).

catch up to Hector....

catch up indicates the fact that Wanda's position will be equal to Hector's position (Pos Hector = Pos Wanda)

And to Hector indicates position. Hector's position

So, at point A we gotta find the time that it would take for Wanda to catch up to Hector.

Wanda's speed (velocity) is greater (higher) than Hector's. Which means, after a definite amount of time, Wanda will catch up to him.

How to find the time it would take for Wanda to catch up to Hector?

Well, we gotta solve for time. We know their velocities, and their distance from eachother.

As we know, the formula for velocity is [tex]V=\frac{d}{t}[/tex]

That is Velocity = Distance divided by time.

We know: Distance, Velocity

So, we need to find the difference between our velocities. That way, we can know how faster you are than him, and in this case, Wanda than Hector.

Vwanda-Vhector = 16miles/hour-12miles/hour

The difference between their velocities is 4miles/hour.

That only means, that Wanda, every hour will walk 4 more miles, than Hector, because she's faster, obviously.

Velocity is 4miles/hour.

The distance will be the distance between the 2 children. That's 18 miles.

V = d/t

4miles/hour = 18miles/t

Let's calculate for t.

Multiply t on both sides.

4miles/hour * t = 18 miles * t / t

the time on the right side cancels out.

4 miles/hour * t = 18 miles.

divide 4 miles/hour on both sides.

4miles/hour * t / 4miles/hour = 18 miles / 4 miles/hour

the 4 miles/hour cancels out on the left side.

t = 18 miles / 4 miles/hour

the miles cancel out, remaining just the hour on the right side.

t = 18/4hours

t = 4.5 hours

If Wanda would travel for 4.5 hours, she will catch up to Hector!

And just like that, we solve A.

Let's move on B, shall we ?

The question is: Will Wanda catch up to Hector before the race is complete? Explain.

Pretty easy.

So, the question asks if Wanda has enough time to catch Hector, before he actually wins.

We know that Wanda's time to catch Hector = 4.5 hours.

What we need to do?

We need to calculate the time it will take Hector to finish the race, and then we'll go to the next step.

Hector's distance to finish the race = 42 miles - 18 miles = 24 miles.

Hector has to go 24 more miles to win.

His velocity is equal to 12 miles/hour.

V = d/t

12 miles/hour = 24 miles / t

multiply t on both sides, and the t on the right side will cancel out.

12 miles/hour * t = 24 miles * t / t

12 miles/hour * t = 24 miles

divide 12 miles/hour on both sides, and on the left side it will cancel out.

12 miles/hour * t / 12 miles/hour = 24 miles / 12 miles/hour

t = 24 miles / 12 miles/hour

The miles will cancel out, on the right side.

t = 24 / 12 hours

t = 2 hours

Now , to finish point B:

Her distance =  42 miles

Her velocity = 16 miles/hour

Time = Distance/Velocity

Her time = 42 miles / 16 miles/hour

the miles will cancel out on the right side

Her time = 42 / 16 hours

Her time = 2.625 hours to reach the finish.

Let's quickly display their times :

Hector : 2 hours

Wanda : 2.625 hours

Wanda did not have enough time to finish.

Hector finished the race in 2 hours, and Wanda in 2,6 hours (aproximately) .

Question: At what constant speed could Wanda travel to catch up with Hector at the finish line? Explain (boring)

At what velocity could Wanda travel at, to catch up Hector and win? That's the question.

Velocity of Hector = 12 miles/hour

Distance of Hector = 24 miles

Time of Hector = 2 hours

------------------------------------------------

Velocity of Wanda = ? (The enough velocity to pass Hector)

Distance of Wanda = 42 miles

Time of Wanda  = ? (It isn't 2.6hours because if Wanda walks faster she would have a smaller time)

Wanda's time = Hector's time, because we want to get at the finish exactly when Hector is at it.

Wanda's time = 2 hours

V = d/t

V = 42/2

V = 21 miles/hour

Just like that.

If Wanda would travel on her bike with 21 miles/hour she would've cought up to her friend.

Answer:

t=100-s

Step-by-step explanation:

Since we know T as the total amount, we need to figure out how much was spent from the $100 Julie has. She can't gain more money magically so you have to take away from the 100. The amount taken away is the S (a.k.a- how much was SPENT). After putting that together, you get t=100-s.

Answer:

Radius: 7 cm, Diameter: 14 cm

Step-by-step explanation:

Correct me if I'm wrong, but I understood that 14 cm is the length of the line segment drawn across the circle. We know that the definition of the diameter is "any straight line segment that passes through the center of the circle and whose endpoints lie on the end of each circle", which can be defined as the line that is shown with a length of 14 cm. It is also known that the radius, a line drawn from the center of the circle to an endpoint, is always half of the diameter, which in this case is 14 cm, so the radius would be 7 cm.

The age of the oldest sibling is 15 years old.

What is consecutive number?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.

Here, let the age of youngest sibling be x years

              the age of middle sibling be (x+1) years

              the age of oldest sibling be (x+2) years

According to question,

        x + (x+1) + (x+2) = 42

          3x + 3 = 42

           3x = 39

             x = 13

Thus, the age of the oldest sibling is (x+ 2) years = 15 years old.

Converting percentages to decimals has you divide the percentage by 100.

So our first equation is full price minus a tenth of that price, leaves you with nine tenths, right? Then we multiply that nine tenths by 8 percent, which is 8 hundredths.

0.9x + 0.072x = 0.972x

Answer:

150 workers are at the company

Step-by-step explanation:

If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so

20% * 5 = 100%

30 * 5 = 150

so 100% of the workers is equal to 150 workers

Step-by-step explanation:

10 ft · 10 ft

100 ft²

[tex]A=\frac{bh}{2}[/tex]

6 · 6 = 36

36 ÷ 2 = 18

18 ft² + 18 ft² = 36 ft²

100 ft² - 36 ft²

64 ft²

Step-by-step explanation:

Solution:

Given,

3 Teacher = 18 students

11 Teacher = X students ( let no. of student be x)

Now,

1 teacher = 18/3

= 6 students

So, If 1 teacher is there then 6 students can play chess.

again,

No. of teacher = 11

No.of students = X

Now,

X= No.of teacher × No.of students for 1 teacher.

= 11 × 6

= 66

So , 11 Teachers can handle 66 students.

There propotion is 11/66 = 1/6 = 1:6.

1:6 is the answer

Answer:

3/8

Step-by-step explanation:

First, find the number of bracelets she's able to make with her string. She has 5/8 of a yard and uses 1/5 per bracelet. To divide the number of yards she has by the number she uses, multiply 5/8 by the reciprocal of 1/5 (5/1).

5/8 * 5/1 = 25/8

25/8 is 3.12500, which is the number of bracelets she can make. It rounds down to 3 since she can't make 0.12500 bracelets.

Now, find how many charms she used. 3 bracelets * 12 charms each is 36 charms in total.

So she used 36/96 of her charms. This can be simplified to 3/8.

Answer:

37/96 hazel has

Step-by-step explanation:

1/5 times 12=60

so Hazel uses 1 yardd for 60 charms, so for 5/8 yard Hazel would use 5/8×60=37.5.

since Hazel isn't able to use a fraction of a charm, she would use 37 charms

37/96 Charms Hazel has
