Question

Solve for y 13.5 12 9 10.5

Answer 1

Answer:

y = 9

Step-by-step explanation:

1. We know that the line the angles fall on is a straight angle, meaning it's worth 180°.

2. Given the information above, 8y + 96 + 12 = 180.

3. (Solving equation above).

Step 1: Simplify both sides of the equation.

• $(8y)+(96+12)=180$
• $8y + 108=180$

Step 2: Subtract 108 from both sides.

• $8y + 108 - 108 = 180 - 108$
• $8y = 72$

Step 3: Divide both sides by 8.

• $\frac{8y}{8}=\frac{72}{8}$
• $y = 9$

Step 4: Check if solution is correct.

• $8(9)+96+12=180$
• $72+96+12=180$
• $168+12=180$
• $180=180$

Therefore, y = 9.
