When n basketball uniforms are purchased, the cost, C, of each uniform is given by the equation.
1 answer:
Answer:
D. Subtraction property of equality; n = 15
Step-by-step explanation:
Given equation that shows the cost of n basketballs uniforms,
C = 40n + 260
According to the question,
Total cost = $ 860,
⇒ 40n + 260 = 860
Using subtraction property of equality, subtract 260 on both sides,
⇒ 40n = 860 - 260
⇒ 40n = 600
Using division property of equality, divide both sides by 40.
⇒ n = = 15.
Hence, 15 uniforms were purchased.
i.e. Option D is correct.

The wheel turned a total of 300 times in 1,884 feet.
Step-by-step explanation:
Step 1:
The wheels of the bicycle have a diameter of 24 inches. So the radius of the wheels is 12 inches.
To determine how many times the wheel turns we divide the distance traveled by the circumference of the wheels.
The circumference of a circle is given by multiplying 2π with the radius.
The circumference of the wheel
The circumference of the wheel is 75.396 inches.
Step 2:
Gia traveled 1,884 feet, we need to convert this into inches.
If 1 feet = 12 inches, 1,884 feet = 22,608 inches.
The number of times the wheel turned
Rounding this off, we get that the wheel turned a total of 300 times in 1,884 feet.
