"<span>y/5+8=7, what is the value of y/5-2?" Simplify the first equation:
y/5 = 7 - 8, or -1, so y/5 = -1, or y = -5.
Then y/5 - 2 equals -5/5 - 2, or -3.</span>
if its diameter is 4 inches, then its radius is half that, or 2 inches.
False because you don’t call or visit the stock market .
(10 + y)² - y² = 3x + 12
(10 + y)·(10 + y) - y² = 3x + 12
10² + 20y + y² - y² = 3x +12
100 + 20y = 3x + 12
100 - 12 = 3x - 20y
3x - 20y = 88
3x - 20 y - 88 = 0 (I suppose it is that one, simplifyied and in order of the letters, or that it you at the previous step)
