Mathematics

Answer:

Step-by-step explanation: x = (82/3) - (7/9)y

Our goal is to get "x" alone on one side. To do this, follow the following steps.

1. Subtract "35y" on both sides

45x = 1230 - 35y

2. Divide "45" on both sides

x = (1230/45) - (35/45)y

3. Simplify the fractions

(1230/45) = 82/3

(35/45) = 7/9

4. Answer is x = (82/3) - (7/9)y

The graph below shows the total cost for lunch, c, when Will and his friends buy a large salad to share and several slices of pi
Helga [31]

Answer:

2.50 dollars.

Step-by-step explanation:

Given:

Will and his friends buy a large salad to share and several slices of pizza, p.

The graph given shows the total cost for lunch, c and slices of pizza,p.

p is marked horizontally, and c vertically.

Observing the points marked we find that for every increase of one slice of pizza, the cost i.e. c on vertical line increases by 0.50 times vertical grid.

Since each grid equals 5 dollars vertically, we find 1/2 grid increase is equal to increase of 1/2(5 ) =2.50 dollars.

Thus for increase of one slice of pizza, 2.50 dollars cost is increased.
