Answer:
White: 28 Blue: 20 Red: 32
Step-by-step explanation: Make ratios. If 35% are White strands then it would be 35/100 = ?/80 you can use the butterfly method to solve this:
35*80 = ?*100
? = 28
Blue: 25/100 = ?/80
(you can use the butterfly method or you can simplify 25/100 into 1/4)
1/4 = ?/80
1*80 = ?*4
? = 20
Red: 40/100 = ?/80 (once again, you can simplify if you want)
4/10 = ?/80
4*80 = ?*80
? = 32
Answer:
O No. She used the wrong slopes when graphing the equations.

I believe the answer is 3*g but don't use x because it could be mistaken as a variable.
Answer:
y =2
Step-by-step explanation:
![77 + 11y = 99](https://tex.z-dn.net/?f=77%20%2B%2011y%20%3D%2099)
Collect like terms and simplify
![11y = 99 - 77 \\ 11y = 22](https://tex.z-dn.net/?f=11y%20%3D%2099%20-%2077%20%5C%5C%2011y%20%3D%2022)
Divide both sides of the equation by 11
![\frac{11y}{11} = \frac{22}{11}](https://tex.z-dn.net/?f=%20%5Cfrac%7B11y%7D%7B11%7D%20%20%3D%20%20%5Cfrac%7B22%7D%7B11%7D%20)
Simplify
![y = 2](https://tex.z-dn.net/?f=y%20%3D%202)
Answer:
The second works better because:
577-479= 577-(477+2)= 577-477-2=100-2=98
