Solve for x over the real numbers:
-x^2 - 12 = -87
Add 12 to both sides:
-x^2 = -75
Multiply both sides by -1:
x^2 = 75
Take the square root of both sides:
Answer: x = 5 sqrt(3) or x = -5 sqrt(3) both Answers are correct
Nine subtracted by a certain number (x)
Hello there!
35% = $14.96
100% = x
Cross multiply
35 * x = 14.96 * 100
35x = 1496
35x/35 = 1496/35
x = 42.74
Thus,
The original price was $42.74
