Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6

Answer:
180
Step-by-step explanation:
So, lets go over what we know:
5% of x = 9
Thinking of this in decimal form, this is:
0.05 * x = 9, or 0.05x = 9
To find the answer, we must multiply both sides to get 1x.
Since 0.05 is 1/20 of 1, we must multiply both sides by 20:
0.05x * 20 = 0 * 20:
1x = 180
So the answer is 180!
Hope this helps!
(x-30)+(x+76)=180
x-30+x+76=180
2x+46=180
2x=134
x=67
67-30=37
67+76=143
<1=37, <2=143
