Answer:

B and D

Step-by-step explanation:

Equations with the same x- term on both sides will have no solution

4x - 13 = 5(x + 4) = 5x + 20

4x ≠ 5x

This equation has a solution

5(3 + 2x) = 10x + 4

15 + 10x = 10x + 4

10x on both sides ⇒ no solution

2(3 - 5x) = 8(x + 1)

6 - 10x = 8x + 8

- 10x ≠ 8x

This equation has a solution

9x - 6 = 3(3x - 2) = 9x - 6

9x on both sides ⇒ no solution

Terrence has 64 stamps. Of his stamps, 12 are from Europe and 1/4 are from Africa. The rest are from Asia. What fraction of his

Tamiku [17]

16 of his stamps are from Africa, since 1/4 of 64 is 16. If I subtract his 28 from Europe and Africa (16 plus 12 equals 28) from his original 64, I am left with 36 stamps. 36/64 is simplified to 9/16. So 9/16 of Terrence's stamps are from Asia.

Bob sees a very tall white pine tree. He estimates that the angle of elevation from him to the top of the tree is 77°

vlabodo [156]

Answer:

86.63 ft

Step-by-step explanation:

The tangent relation applies.

Tan = Opposite/Adjacent

tan(77°) = (tree height)/(20 ft)

tree height = (20 ft)·tan(77°) ≈ 86.63 ft

_____

<em>Additional comment</em>

It is somewhat problematic for Bob to see the top of a white pine tree at that angle of elevation. His view would likely be obscured by the branches of the tree.
