Answer:
x = ± 4/5
Step-by-step explanation:
25 x^2 = 16
Divide each side by 25
25 x^2 /25 = 16 /25
x^2 = 16 /25
Take the square root of each side
sqrt(x^2) = ±sqrt(16/25)
We know that sqrt(a/b) = sqrt(a)/ sqrt(b)
x = ±sqrt(16) / sqrt(25)
x = ± 4/5
In order to solve this we must first,
Subtract both sides of the equation by 10,
y-10=1/2x
Now we have to multiply both sides by 2 so that only x is left.
2y-20=x
Therefore, x=2y-20

Here's my answer. I'm not too sure how to form the equation though. Hope this helps :)
Answer:
The answer to your question is A.35
X+(x+18)=$56
56-18=38
38/2=19
She spent $19 on accessories
19+18= $37 on clothes
$37+$19=$56
