Solving equations simple
9n + 12 = 30
Answer:
x = 33.33 kilometers
Step-by-step explanation:
you could make use of the percent, base, and rate formula here. we know that 15% is the rate, 5 kilometers is the percent, therefore what we are looking for is our base.

; cross multiply.
15x = 500
x = 33.33 kilometers
therefore, the race is 33.33 kilometers.
Answer: The answer for x is 6.75. The answer for y 6.75.
Step-by-step explanation:
You are going to mutiple 0.75 x 9 = 6.75. Then, mutiple 0.50 x 9= 4.5. Hope this works.
