<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.
Answer:try and solve it yourself
Step-by-step explanation:
Answer- 85,7 g
300:7= 42,85
42,85x2=85,7
The answer should be f(x)=9x + 60
Find angleK:
Angle k = 180-45-85 = 50
Both triangles have an angle equal to 85 and 45, which makes the 3rd angle in both triangles equal to 50
Because all three angles are the same the triangles are similar.
