Question

Is 70 the correct value for x?

Answer 1

Answer:

68 is what I'm getting for x

70 is the correct length of DH

Step-by-step explanation:

You can set up the proportion for this question.

99.2 / 62 = 112/(x + 2)   Cross multiply

99.2 ( x + 2) = 62 * 112   Combine the right side

99.2(x + 2) = 6944         Use the distributive principle to remove the brackets.

99.2*x + 2*99.2 = 6944 Combine the factors on the left

99.2x + 198.4 = 6944     Subtract 198.4 from both sides

99.2x = 6944  - 198.4     Combine the terms on the right

99.2x = 6745.6               Divide both sides by 99.2

x = 6745.6/99.2

x = 68

DH = 70
