Answer:
D
Step-by-step explanation:
Simplify and rearrange to solve.
2/3 (cx + 1/2) - 1/4 = 5/2
2/3 (cx + 1/2) = 5/2 + 1/4
2/3 (cx + 1/2) = 11/4
cx + 1/2 = 11/4 divided by 2/3
cx + 1/2 = 33/8
cx = 33/8 - 1/2 = 29/8
x= 29 / 8 divided by x = 29/8c.
Hope this helps.
Answer:
39,51
Step-by-step explanation:
Complementary angles add to 90 degrees
Let one angle be x
The other angle is x+12
x+ x+12 = 90
Combine like terms
2x+12 = 90
Subtract 12 from each side
2x+12-12 = 90-12
2x = 78
Divide each side by 2
2x/2 = 78/2
x =39
The other angle is 39+12 =51
