Answer:
51.25 (or 51 1/4)
Explanation:
4x + 5 ÷ 8x + 5
Substitute 10 for x into the expression.
4(10) + 5 ÷ 8(10) + 5
Start by multiplying 4 and 10.
40 + 5 ÷ 8 * 10 + 5
Now divide 5 and 8.
40 + 0.625 * 10 + 5
Multiply 0.625 and 10.
40 + 6.25 + 5
Add them all together.
51.25
If you want your answer in fraction form it would be 51 1/4.
