Answer:
C.7 weeks
Step-by-step explanation:
Subtract 60 on both sides then you get: 30w=210, then divide both sides and you get w=7, so it'll take 7 weeks
Answer:
C. 7 weeks
Step-by-step explanation:
30w + 60 = 270
- 60 -60
subtract 60 from both sides of the equal sign.
30w = 210
We need to isolate the variable, which is (w), so divide both sides by 30.
w = 7
It will take 7 weeks for Uma to save enough money to buy the video game system. So the answer is (c).

Answer:
60
Step-by-step explanation:
Just use similar triangles.
12/10 = 72/x
Now solve for x.
x = 72 * 10 / 12 = 60
Plug in 83 for y and 3 for x
83 = 3^2 - 6 (3) + 92
83 = 9 - 18 + 92
83 = -9 + 92
83 = 83 so it works
