Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes

Answer:
Step-by-step explanation:
31 - 12n = 21l Subtract 31 from both sides.
31-31-12n =211-31 Do the subtraction
-12n = 190 Divide by -12
-12n/-12 = 190/-12
n = -15.333333
