It equals twelve. hope it helps :)
Answer:
The answer is D
Step-by-step explanation:
R and A both have the one line thingy and s and b have both the 2 line thingies. so <BAC=<SRT
2/5 ÷ x = 4/5
multiply both sides by x to get it out of the denominator.
2/5 = 4/5x
now divide each side by 4/5 to get x by itself.
2/5 ÷ 4/5 = x
divide fractions by multiplying the reciprocal of the divisor.
2/5x × 5/4 = x
10/20 = x
1/2 = x
So 2/5 divided by 1/2 =4/5
Answer:
(2,5) (7,9) (3,9) (5,8)
The relation is a function.
