Answer:

Option D  is best modeled with a division expression

Step-by-step explanation:

A)  How much does it cost to buy 3 and 1/2 pounds of apples at $2 per pound?

Cost of 1 pound = $2

Cost of 3 and 1/2 pounds  = 2 \times 3.5

B) B. How many apples are needed for 2 pies if the recipe uses 3 and 1/2 apples per pie?

1 pie requires 3.5 apples

So, 2 pies requires apples = 3.5 \times 2

C)  How many more apples are needed if a recipe uses 3 and 1/2 apples and you only have 2 apples?

Recipe requires 3.5 apples

You have 2 apples

More apples required = 3.5 - 2

D) . How many apples are in each pie if a total of 3 and 1/2 apples were used to bake 2 pies?

Apples required in 2 pies = 3.5

Apples required in 1 pie = \frac{3.5}{2}

Hence Option D  is best modeled with a division expression

a rectangular room is 4 times as long as it is wide and it's perimeter is 60 meters find the dimension of the room
olya-2409 [2.1K]

To answer this problem we have to use two different variables. For example...

L = Length

W = Width

So we know that the definition of perimeter is

L + L + W + W (or all the sides added up)

Now we also know that The Length is 4 times longer than the width.

So we can write 4W to replace the L

So in the given equation we set up Replace every L with 4W

4W + 4W + W + W = 60 meters

now group our W's

10W = 60 divide both sides by 10 to get W to be alone

÷10   = ÷10 It cancels on the left side and we solve on the right side.

W = 6

So now that we know what the width equals we can find what the length equals .

Remember this?

4W = L (plug in 6 for W)

4(6) = L

So L = 24


Our dimensions of this rectangle are length 24, width 6.


Good Luck! :)

Arthur answered 85 out of 95 questions correctly on his math exam. Miguel answered 64 out of 76 questions correctly on his histo
Anarel [89]

For this type of question, we have to take out the percentage of each candidate:

For Arthur

85 from 95

Convert   95 to 100

That means that we have to add 5, do the same thing with 85. Add 5 to 85 and you get 90. That means Arthur got  90% For Miguel 64 from  76. Covert 76 to 100. That means we have to add 24. Do the same thing with 64. Add 24 + 64. It equals 88% Miguel got 88%

Slope: 0<br> y-intercept: -2<br> .
Nookie1986 [14]

Answer:

The linear equation is the equation of straight line. where m is the slope of the line and c is the y-intercept. Thus, the y-intercept is expressed as (0, c). That is where the graph intercepts the y-axis (thus, the x value would be 0).
