Answer:

Step-by-step explanation:

Simplifying

2(4x + 1) = 18

Reorder the terms:

2(1 + 4x) = 18

(1 * 2 + 4x * 2) = 18

(2 + 8x) = 18

Solving

2 + 8x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 8x = 18 + -2

Combine like terms: 2 + -2 = 0

0 + 8x = 18 + -2

8x = 18 + -2

Combine like terms: 18 + -2 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2

Answer:

$20.97

Step-by-step explanation:

3 people, meaning to multiply each one by 3.

Total price of Hot Dogs= 9.00

Total price of Fries=7.47

Total price of Drinks=7.50

7.50 - 3= $4.50

9.00+7.47+4.50= $20.97

The length of the side is 1/√2 or √2/2 units after applying the sin ratio.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Using sin ratio to find the value of x:

sin45 = X/1

1/√2 = X/1

X = (1/√2)(√2/√2)

X = √2/2

Thus, the length of the side is 1/√2 or √2/2 units after applying the sin ratio.

Step-by-step explanation:

5 % of 20 is 1

Answer:

The answer would be $87.20

Step-by-step explanation:

Because if it is 20 % off you would multiply it by 0.2 which would get you 21.8

Then, 109 - 21.8 is 87.20

Answer: 32

Step-by-step explanation:

If you divide 32 by 8 then you get 4

If Connor buys 3 snacks at 3 dollars each for himself and his 3 children, the net cost (including movie tickets) would be 88 dollars.

If he buys x amount of snacks, his cost will be determined by C=52+3x or C=52+3*x (both are equivalent, but not everyone knows every way to represent multiplication)

Step-by-step explanation:

To find the cost of the snacks:

Cost = Price*NumberOfSnacks, or C=p*n, or C=pn

To find the unit cost of the snack, find the price, the p value, which is 3 dollars.

Then, find the total number of snacks that will be bought. Since each person receives an equal number of snacks, 3 per person, and there are 4 people (himself and his 3 children), we can multiply 3*4 to find the n value, which is now known to be 12.

C=3*12=36. Add to the 13 dollar per person charge for tickets (52 dollars for 4 people), and you get 88 dollars.

To find the cost if he buys x amount of snacks for himself and his 3 children (assumed to be "everyone"), all costs but the n value are to be the same, creating this equation:

C=52+3x

In this context, 52 is the cost of movie tickets, 3 is the cost of the snacks, and x is the total number of snacks bought. C represents total cost.

The total cost for tickets and 5 snacks is $90.

The total cost for tickets and x snacks is $(65+5x).

Important information:

The total number of people is 5. So, cost of 5 tickets is:

[tex]5\times 13=65[/tex]

Cost of 5 snacks is:

[tex]5\times 5=25[/tex]

Total cost is:

[tex]65+25=90[/tex]

The total cost for tickets and 5 snacks is $90.

Cost of x snacks is:

[tex]5\times x=5x[/tex]

Total cost is:

[tex]65+5x[/tex]

The total cost for tickets and x snacks is $(65+5x).

Answer:

she ran 10 miles a hour

Step-by-step explanation:

she runs 10 miles a hour because she wants to improve her time per mile by 2 minutes so you do 2x4 and get 8, then you subtract 8 from 48 and get 40 then you divide 40 by 4 and get 10

Heather's rate of speed last week was 1/12 miles/min.

Given is that last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.

Heather's rate of speed last week -

{r} = 4/48 = 1/12 miles/min

{r} = 1/12 miles/min

Therefore, Heather's rate of speed last week was 1/12 miles/min.

Answer:

D

Step-by-step explanation:

All real numbers are solution

Step 1: Simplify both sides of the inequality.

8x−7<8x−3

Step 2: Subtract 8x from both sides.

8x−7−8x<8x−3−8x

−7<−3

Step 3: Add 7 to both sides.

−7+7<−3+7

0<4

Answer:

[tex]-6-7\left(c+10\right)=-7c-76[/tex]

Step-by-step explanation:

Given the expression

[tex]-6\:-\:7\:\left(c+10\right)[/tex]

simplifying the expression

[tex]-6-7\left(c+10\right)[/tex]

Expanding -7(c + 10) = -7c - 70

[tex]-6\:-\:7\:\left(c+10\right)=-6-7c-70[/tex]

subtract the numbers: -6 - 70 = -76

                           [tex]=-7c-76[/tex]

Therefore, we conclude that:

[tex]-6-7\left(c+10\right)=-7c-76[/tex]

Answer:

it is a solvable equation

Step-by-step explanation:

(x + 2) -3(x - 4) = 6 and x = 4

if x = 4 then fill in all the x's with 4 so the equation is now:

(4 + 2) -3(4 - 4) = 6

Use PEMDAS

Now the equation is 6 - 3(0) = 6

-3 times 0 is 0 so it's 6-0=6

6 = 6

when you put the 4 in for the x variables and the numbers on both sides of the equal sign are the same it makes the equation true

hope this makes sense and hope it helps :)
