Answer:

2. D  [tex]\frac{1}{2}[/tex] inch per hour

3. C    [tex]\frac{4}{5}[/tex] km

Eli chose A because he multiply 5[tex]\frac{3}{5}[/tex] km and 7 days; instead of dividing.

[tex]\frac{28}{5}[/tex] * 7= [tex]\frac{196}{5}[/tex] which is 39[tex]\frac{1}{5}[/tex]

Step-by-step explanation:

2. Divide the inches of rain by hours

12[tex]\frac{1}{4}[/tex] inches of rain ÷ 25[tex]\frac{1}{2}[/tex] hours; convert to proper fraction

[tex]\frac{49}{4}[/tex] ÷ [tex]\frac{51}{2}[/tex]

[tex]\frac{49}{4}[/tex] * [tex]\frac{2}{51}[/tex] = [tex]\frac{98}{204}[/tex] = [tex]\frac{49}{102}[/tex] which is approximately [tex]\frac{1}{2}[/tex] inch per hour

3. Divide km by days

5[tex]\frac{3}{5}[/tex] km / 7 days = [tex]\frac{28}{5}[/tex] ÷ 7 =  [tex]\frac{28}{5}[/tex] * [tex]\frac{1}{7}[/tex] = [tex]\frac{4}{5}[/tex] km

Eli chose A because he multiply 5[tex]\frac{3}{5}[/tex] km and 7 days; instead of dividing.

[tex]\frac{28}{5}[/tex] * 7= [tex]\frac{196}{5}[/tex] which is 39[tex]\frac{1}{5}[/tex]

Answer:

2: A      About  1/2 inches

12 1/4 divided by 25 1/2= 49/102 via Approximately 1/2

3:  C.      4/5

Answer:

18k

Step-by-step explanation:

To solve this, you must first multiply -3 by (10+3k). This leaves you with -30-9k. Next, compare which values you need to make the two equations equal. -30=-30, but -9k does not equal 9k. So, you need to add 18k to make the equations equal.

Answer:

Let(-4,6)and (3,-7) be named as A and B

A(-4,6) (x1,y1)

B(3,-7) (x2,y2)

distance between AB= square root(x2-x1)^2+(y2-y1)^2

AB= square root(3-(-4)^2+(-7)-6)^2

AB= square root(3+4)^2+(-13)^2

AB= square root(7)^2+169

AB= square root(49+169)

AB= square root218

AB=14.76 Answer!!!

Answer:

Option (3) and Option (5)

Step-by-step explanation:

By the property of a triangle,

Sum of interior angles of a triangle is 180°.

m∠Q + m∠R + m∠S = 180°

By substituting the measures of angles in the equation,

(8x - 17)° + (19x + 4)° + (5x + 1)° = 180°

32x - 12 = 180

32x = 192

x = 6

m∠Q = (8x - 17)° = 48 - 17

                          = 31°

m∠R = (19x + 4)° = 114 + 4

                           = 118°

m∠S = (5x + 1) = 30 + 1

                       = 31°

Since, one interior angle measures 118° which is grater than 90°.

Therefore, triangle QRS is an obtuse triangle.

Since, m∠Q = m∠R = 31°

It's an isosceles triangle.

Option (3) and Option (5) are the correct options.

Answer:

How much would it cost to buy 10 pounds of peanuts?

Answer: $35

What is the cost per pound?

Answer: $3.50

Step-by-step explanation:

So first, to find the anser to the first question, we need to find out the second question. So, what is the cost per pound.

Well if she got 4 pounds for $14, we should try dividing 14 by 4.

14 divided by 4 = 3.5 ($3.50)

So the cost per pound is $3.50

Now to find out how much it costs if Lulu bought 10 pounds, we need to multiply.

10 x 3.5 = 35

So if she bought 10 pounds, she would play $35

Answer:

A

Step-by-step explanation:

Answer:

1. Multiply 2/7 by 3/5

Solution:

2/7 × 3/5

= 2 × 3/7 × 5

= 6/35

2. Multiply 5/9 by (-3/4)

Solution:

5/9 × (-3/4)

= 5 × -3/9 × 4

= -15/36

= -5/12

Step-by-step explanation:

Answer:

Dividing is like multiplying fractions.

Also, dividing integers is the opposite of multiplication of integers.

x * y = z

z / y = x

Answer:

To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer. When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.

Answer:

Time of arrival in Auckland is 7:15 am on 7th December

Step-by-step explanation:

Here, we want to find the time and date of arrival of the plane in Auckland

The time it leaves london is 15:45 on 5th December

Since Auckland is 13 hours ahead, the time at Auckland will be 4;45 am on 6th december

So taking 26 hours 30 minutes

Let’s take 24 hours first;

That will be 4:45 am on 7th december

Then another 2 hours 30 minutes ;

That will be 7:15 am, 7th December

Answer:

The given system of linear equations has infinite many solutions.

Step-by-step explanation:

Given equations are

σ-2ζ=3       eqn 1

4σ-8ζ=12   eqn 2

We will use elimination method to solve the linear system

Multiplying equation 1 by 4

4(σ-2ζ) = 4(3)

4σ-8ζ=12

We can see that the both equations in the system are same i.e. we get the same equations by simplifying the equations. The graph of both equations will overlap completely.

This means that the system has infinite many solutions.

Hence,

The given system of linear equations has infinite many solutions.

Answer:

he will need 7.5 cups of flowers or 7 2/4

Step-by-step explanation:

So basically you have to keep adding 5/4 for every 1/2 you get until you reach 3.So when you do this you get 7.4.

A faster way to do this is to find how 1/2 are in 3 cups and then multiply that by the 5/4.

Answer:

-2/2 or -1

Step-by-step explanation:

Answer:

1. (-4,0) and (-2,0)

2. (2,0)

3. (2,0)

4. (-6,0), (-2,0), (2,0), and (6,0)

Step-by-step explanation:

The x-intercepts are the points in which the line crosses the x-axis. Another word for this are the zeroes, because y=0 would be right on the x-axis, and finding the zeroes would be finding the points that cross y=0. Notice how the points listen on the answer are right on the x-axis of each graph; they intercept the x-axis.
