Answer: he worked 32 hours and make $512
(This is a little difficult but I've got it)
((x - 45)/12) + 20 = 5(32 - x)
(I made the equation a little more complex than I should have but that equation should still work if you were to solve for x)
Answer:
6.7 * 10^7
Step-by-step explanation:
X^2 + 5x - 5 = 0
This is a quadratic equation that cannot be factored. It can be solved using the quadratic formula or by completing the square.
the quadratic formula is x = (-b +-sqrt(b^2 - 4ac))/2a
a is the coefficient of the x^2, b is the coefficient of the x, and c is the constant.
a = 1, b = 5, c = -5
x = (-5 +- sqrt(25+20))/2
x = (-5 +- sqrt(45))/2
x = (-5 + - 3 sqt 5))/2
x = (-5 + 3sqrt5)/2 and x = (-5 - 3sqrt5)/2
Answer:
AB=24.5
Step-by-step explanation:
5x+7=7x
7=2x
x=3.5
7(3.5)=24.5
