<u>Answer:</u>
The correct answer option is D. He multiplied the divisor by 100 and dividend by 10.
<u>Step-by-step explanation:</u>
We are given that Miguel completed the division where initially he had to divide 754 by 0.52.
To make it easier, he multiplied both the divisor and the dividend by the same number to get rid of the decimal in the divisor.
If he multiplied the divisor by 100, he should have multiplied the dividend by 100 too. But instead, he mistakenly multiplied the divisor by 100 and dividend by 10.
Because QRST is a rectangle, that means all of the angles must be a right angle, which are 90 degrees. Using this information, solve the expression by creating an equation that lets angle S = 90.
90 = 7x + 55
35 = 7x
x = 5
