In the equation, 7 (3a+12)=168 , what are some of the steps that should be taken to solve for x? Select all that apply.
Svetradugi [14.3K]

7(3a + 12) = 168 ← ( divide both sides by 7 )

3a + 12 = 24 ← ( subtract 12 from both sides )

3a = 12 ← ( divide both sides by 3 )

a = 4

OR

distribute the parenthesis by 7

21a + 84 = 168 ← ( subtract 84 from both sides )

21a = 84 ← ( divide both sides by 21 )

a = 4

Two angles form a linear pair. If the measure of one angle is 47, what is the degree measure of the other angle?
cupoosta [38]

Answer:

The other angle would be equal to 133 degrees.

Step-by-step explanation:

All linear pairs are supplementary angles, which means that they are equal to 180. So we can find the second angle by using the following angle.

47 + x = 180

x = 133
