Answer:
5/8
Step-by-step explanation:
1/4=2/8 (This is to find a common denominator).
2/8+3/8=5/8 (When adding fractions, ONLY add the numerator, not the denominator).

8 = x% * 400
8 = x/100 * 400
8 = x * 4
4x = 8
Divide 4 on both sides.
x = 8/4
x = 2
2 percent<span> of 400 is 8.</span>
Answer:
A possible tape diagram to represent the context if a represents the number of gigabytes of data Abigail can use while staying within her budget is as follows:
52 + 4a = 62
This tape diagram would show that for every gigabyte of data that Abigail uses, she would need to pay an additional $4 on her monthly bill, with a base monthly cost of $52. In order to keep her monthly bill at $62, she would need to use a maximum of 10 gigabytes of data.
15. First Distribute
-6x-4 = 2X + 6
Add 6X on both sides
-4 = 8x+6
Subract 6 on both sides
8x=-10
Divide by 8 on both sides
X = -10/8 = -5/4
16. -13
17. Cross Multiplication
32 = 3X-3
Add 3 on both sides
35 = 3X
Divide by 3 on both sides
35/3 = X
18. Can't see the whole picture
19. Add 7 on both sides
6N = 42. Divide by 6
N = 7
20. 2x+6=-x+1. ---- I cross multiplied
2x+5=-x. ---- I subract 1 on both sides
-3x = 5. ----- Subract 2X
X=5/-3 ---- I divided it by -3
