Answer:
X=(6x+1)(x-1) because you are factoring out
Step-by-step explanation:
1. Use exterior angles (each adds up to 360) to find interior angles
2. Add this together
3.Take it away from 360
Black keys=b
white keys=w
b+w=88|·9
w:b=13/9⇒9w=13b
9b+9w=792
13b+9b=792
22b=792|:22
b=36 keys
w=88-36
w=52 keys
Answer:
Inspection fee = $50
h = 2 hours
Step-by-step explanation:
Let
x = the inspection fee
Charge per hour = $22
Number of hours = 4
A customer with a coupon for 40% off the inspection fee
This means the customer paid 60% of the inspection fee
118 = 60% of x + 22(4)
118 = 0.6x + 88
118 - 88 = .6x
30 = .6x
x = 30/0.6
x = $50
Inspection fee = x = $50
How many hours are worked when a customer pays $94 without a coupon?
94 = 50 + 22h
94 - 50 = 22h
44 = 22h
h = 44/22
h = 2 hours
