Answer:

y = 3

Step-by-step explanation:

9 - y = 2y

<u>Step 1:  Add y to both sides</u>

9 - y + y = 2y + y

9 = 3y

<u>Step 2:  Divide both sides by 3</u>

9 / 3 = 3y / 3

3 = y

Answer:  y = 3

The insurance company should charge $6,000.

Step-by-step explanation:

(a) 30,000 × .6 + (-15,000) × .4 = 12,000.

(b) 15,000 × .4 = 6,000.

Can someone help with this problem
WARRIOR [948]
35+25=60
y=60


If you add the opposite side values of the triangle (not the one touching the y), you get the value of y). 35+25=y
This works because y+x= 180 and the three angles of a triangle add to 180.
