Answer:
10
Step-by-step explanation:
Square = 2 x 2 = 4
The Small triangle is half of the square so 4 divided by 2 is 2.
The big triangle 4 x 2 = 8 divided by 2 is 4.
So,
4 + 2 + 4 = 10
You add +7 to both sides and then divide by 9 to get the x alone.
So, we need to add.
45 + 30 = 85.
$0.85 is your answer.
Glad I could help, and good luck!
