Answer:
Divide by 2
Then subtract 4
Step-by-step explanation:
Let y = 2(x+4)
Exchange x and y
x = 2(y+4)
We want to solve for y
Divide each side by 2
x/2 = y+4
Then subtract 4 from each side
x/2 -4 =y
The inverse is x/2 -4
Answer:
400
Step-by step explanation:
The sides of the regular polygon is 20 and more than 2 so you divide the two number up to get 10 and then also you multiply all of them up together which is 400
Answer:
x = 19.
Step-by-step explanation:
By the tangent - secant theorem:
BD^2 = AB * EB
so:
8^2 = (x - 7 + 4) * 4
4(x - 3) = 64
4x - 12 = 64
4x = 64 + 12 = 76
x = 76/4
= 19.
Answer:
$7.55
Step-by-step explanation:
We have been given that at a local gas station regular gasoline sale for $2.89 per gallon while premium gasoline sale for $3.39 per gallon. We are asked to find the amount saved by a person on buying 15.1 gallons of regular gasoline.
