Answer: |-30| + |25|
Step-by-step explanation:
11. x = 10, so DCE is 72. You get the measurement of x by adding 7x + 2 and x + 8 to equal 90. When you get x, you plug it in to the equation for DCE.
12. x = 17. KNM is 131. Get the measurement of x by adding both equations again, this time equaling it to 180 since it is a straight line and doesn't have a right angle. Plug in the x to the equation for KNM.
<u>Answer:</u>

D. 16
<u>Step-by-step explanation:</u>
We are given a number of incomplete fractions and we are to find the missing numerator in each one of these.
To find the missing numerator or denominator, we multiply the numerator and the denominator by the same number to get an equivalent fraction.
A. 
Here the denominator is multiplied by 2 so the denominator will also be multiplied by 2 to get 10.
