Answer:
Step-by-step explanation:
3(x - 7) = 30 is our equation, since we take 7 away from the number and then multiply the result by 3.
3x - 21 = 30
Add 21
3x = 51
Divide by 3
x = 17
To check.
3(17 - 7(
3(10)
30 = 30 Correct
(0, 0) → t = 0, w = 0 → w = 0 · 0
(1, 4) → t = 1, w = 4 → w = 1 · 4
(2, 8) → t = 2, w = 8 → w = 2 · 4
(3, 12) → t = 3, w = 12 → w = 3 · 4
