Answer:
y=60
Step-by-step explanation:
Multiply the x by 4
Distribute
5x-10=20+2x
minus 2x both sides
3x-10=20
add 10 both sides
3x=30
divide both sides by 3
x=10

Answer:
<u>Earnings of Chris that week = US$ 712.65</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Chris' salary = US$ 6 per hour + 0.9% commission (0.009)
A week Chris worked 32 hours and sold 2 cars priced $ 26,700 and $ 31,150
2. How much did he make that week?
Earnings of Chris that week = (32 * 6) + (26,700 * 0.009) + (31,150 * 0.0009)
Earnings of Chris that week = 192 + 240.30 + 280.35
<u>Earnings of Chris that week = US$ 712.65</u>
Answer:
The factored form of the equation is (x+4)(x-6)=0.
Step-by-step explanation:
Because (x-4)(x+2)=x^2-4x+2x-8=16,
so that means x^2-2x-8=16,
move 16 to the other side,
you get x^2-2x-8-16=0,
simplify,
you get x^2-2x-24=0,
which satisfies (x+4)(x-6)=0 when factored out.
Because (x+4)(x-6)=x^2+4x-6x-24=x^2-2x-24=0.
