9. Let p = Pico

3/4p = 18

10. Let h = height with pedestal and foundation

151 + h = 305

11. Let m = Meredith

19 = 3 + 2m

12. Let p = number of pizzas, $5 off is - 5 from regular price

3p - 5 = 21.75

13. Option C.

14. Option A. 

15. Let w = last week's miles

w = \frac{1}{2}(12) + 3

The word "half" tells you to use 1/2 in the equation. The phrase "three more than" tells you to use + 3. We multiply 1/2 by 12 (or divide 12 by 2; it's the same thing) because we are taking half of the miles Carmen ran "this week" as stated in the problem.

The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
Katarina [22]

Answer:

The dependent variable is the distance, the equation is y = 22x, and the dragonfly will travel 528 miles.

Step-by-step explanation:

See the graph attached.

It is clear from the graph that the dependent variable is distance and the equation of the straight line is y = 22x, where x is the independent variable times in hours and y is the dependent variable distance in miles.

Now, for x = 24 hours, from the equation we get, y = 22 × 24 = 528 miles.

So, the dragonfly will travel 528 miles. (Answer)
