It took Aiden 6 hours to plant 8 trees. How many hours would it take for him to plant 20 trees? 24, 18, 23, 15

Pepsi [2]

<h3>Answer: 15 hours (choice D)</h3>

================================================

Work Shown:

(6 hours)/(8 trees) = (x hours)/(20 trees)

6/8 = x/20

6*20 = 8*x ... cross multiply

120 = 8x

8x = 120

x = 120/8

x = 15

It takes him 15 hours to plant 20 trees.

Measure the angle of 10x+10

Elena L [17]

Answer:

We know that opposite angle are congruent.

$10x + 10 = 11x + 3 \\ \\ 10x - 11x = - 7 \\ - x = - 7 \\ x = 7$

So, We found out that x = 7,

So, Putting x = 7 in 10x+10

$10 \times 7 + 10 \\ \\ = 70 + 10 \\ \\ = 80$

So, The measure of angle 10x+10 is 80.
