Answer:
144 169 225
Step-by-step explanation:
12² = 144
13² = 169
15² = 225
You simply put 40 over a hundred and 55 over n (which is the number were trying to find) so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.
Answer:
y = 2.5x + 0
Step-by-step explanation:
Use the slope formula and slope-intercept form y = mx + b to find the equation.
7z + 10 - z = 8z - 2(z - 5)
7z + 10 - z = 8z - 2z + 10
6z + 10 = 6z + 10
6z - 6z = 10 - 10
0 = 0
Therefore, 7z + 10 - z = 8z - 2(z - 5)
