Answer:
33+15w=3w-w+4w
33+15w - 15w=3w-w+4w -15w
33 = 2w + 4w -15w
33 = 6w -15w
33 = -9w
33/9 = -9/9w
3.66 = w
Step-by-step explanation:
33+15w=3w-w+4w
33+15w - 15w=3w-w+4w -15w
33 = 2w + 4w -15w
33 = 6w -15w
33 = -9w
33/9 = -9/9w
3.66 = w
They are both equal because in decimals you can add thousands of zeros and it's still equal.

Answer:
I would set this up as:
let: lesser number = x
greater number = 2x + 5
Restating the word problem:
lesser number + greater number = 38
x + 2x + 5 = 38
Solving: 3x + 5 = 38
- 5 -5
---------------
3x = 33
--- ---
3 3
x = 11
Substitution for the greater number:
2(11) + 5
22 + 5
27
If the quiz is worth 50 points and each question is worth 10 that means for every question he could’ve missed would be taking away 10 from that 50. So lets say if he misses 2 questions. 2 x 10 would be 20. You take away 20 from 50 which would be: 50 - 20 = 30. And it goes on from there.
Hope that helps!
