Answer:
pretty sure its B and C
Step-by-step explanation:
because they have a common multiplier of 2.5 and are similar triangles
18 x 2.5 = 45
20 x 2.5 = 50
The answer is x = 78/5
<span>(1/5) (5x + 12) = 18
</span>
Multiple both sides by 5:
<span>5 * (1/5) (5x + 12) = 5 * 18
5x + 12 = 90
Subtract 12 from both sides:
5x + 12 - 12 = 90 - 12
5x =78
Divide both sides by 5:
5x/5 = 78/5
x = 78/5</span>
Answer:
Therefore 6th year his income was $19,700.
Step-by-step explanation:
Given, Joe's annual income has been increasing in some dollar amount . The first year his income was $15,200 and 4th year his income was $17,900.

Let year Joe's income was $19,700.
≈6
Therefore 6th year his income was $19,700.
Answer:
m = -5/4n -2
Step-by-step explanation:
-5n=4m+8
-8 -8 Subtract 8 from both sides
-5n - 8 = 4m
-5/4n -2 = m Divide both sides by 4
