12. Michelle is selling her condo. She needs to make at least $42,000 from the sale so she can make a down payment on a new house. If a 5.5% real estate commission is deducted, what is
the lowest offer Michelle should accept to get her down payment?

Total amount she need = $44,444

Step-by-step explanation:

Given:

Amount Michelle needs = $42,000

Real state commission = 5.5%

Find:

Total amount she need

Computation:

Assume,

Total amount she need = x

So,

Real state commission = 0.055x

So,

x - 0.055x = 42000

x (0.945) = 42,000

x = 44,444 (Approx)

Total amount she need = $44,444

i think the answer is fried chicken ; >

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
