1/40 = .025, just multiply this by 21 and you have your answer
.525
2 and 8 are alternate exterior angles
20/2.5 = 8
So 8 movies can be shown in 20 hours.
Multiply 2/1 or 2 on both sides to get "y" by itself

y ≤ -14
Answer: $48
Step-by-step explanation:
From the question, we are told that in Michigan, the sales tax rate is 6% and that an item costs $50.88 including tax.
Let the cost of the item before tax be x. This means that x plus 6% of x equals to $50.88. This can be mathematically expressed as:
x + (6% of x) = $50.88
x + (6/100 × x) = $50.88
x + (0.06 × x) = $50.88
x + 0.06x = $50.88
1.06x = $50.88
When then divide by the coefficient of x
1.06x/1.06 = #50.88/1.06
x = $48
The price before the tax is $48
