4
Step-by-step explanation:
Answer:
15 & 7
Step-by-step explanation:
f - s = 8
f = 8 + s
Twice the first number plus three times the second number is 51:
2f + 3s = 51
Substitute:
2(8 + s) + 3s = 51
16 + 2s + 3s = 51
16 + 5s = 51
5s = 51 - 16
5s = 35
s = 7, the second number
Find f:
f = 8 + 7 = 15, the first number
f - s = 8
15 - 7 = 8
8 = 8
The answer is z=120 because you need to isolate z and to do that you must multiply each side by 12 and you end up with z=120

Answer:<em>r = d/t</em>
Step-by-step explanation:
1. If we are solving for <em>r, </em>we need to have <em>r</em> on one side of the equation.
2. Divide by t on both sides = d/t=r
