Divide 10 by 25, which would get you 4. Move the decimal over two to the left, because you wanted a percentage.

Answer:
B.
Step-by-step explanation:
y = x^2 - x - 12
y = (x-4)×(x+3) that means x it either 4 or -3
y = x + 3
for x = 4 ➡ y = 3+4 ➡7
for x = -3 ➡ y = -3 + 3➡0
(the answer key is most probably faulty there's no way for y to be 0 in both scenarios)
X + y = 405
y = 8x
To solve:
Plug the second equation into the first and solve for x.
x + 8x = 405
9x = 405
Divide both sides by 9
x = 45
Use the second equation to find y.
y = 8(45)
y = 360
