Question

how many inches are in 3 yards? *
108 inches
36 inches
9 inches
324 inches

solve for x: 2x - 10 =12 *
x = 1
x = 11
x = 2
no solution

Explanation:

Step1: Convert yards to feet

1 yard = 3 feet, so $3 \text{ yards} = 3 \times 3 = 9 \text{ feet}$

Step2: Convert feet to inches

1 foot = 12 inches, so $9 \text{ feet} = 9 \times 12 = 108 \text{ inches}$

Step3: Isolate the term with x

Add 10 to both sides: $2x - 10 + 10 = 12 + 10$ → $2x = 22$

Step4: Solve for x

Divide by 2: $x = \frac{22}{2} = 11$

Answer:

1. 108 inches
2. $x=11$
