Complete question :

The sugar maple tree in Joshua's yard is 1/4 the age of the oak tree in his yard. The sugar maple tree is 20 years old. How old is the oak tree?

80 years

Step-by-step explanation:

Given that :

Sugar maple tree = 1/4 age of oak tree

Age of sugar maple tree = 20

Age of oak tree = x

20 = 1/4 * x

20 = x / 4

Multiply both sides by 4

20 * 4 = (x / 4) * 4

80 = x

Hence, Age of oak tree = 80 years

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m
