Write equations for the given information to solve (using J for Jeanine and M for Marc):
J=2M
J+M= 24
Now substitute 2M in for J in the second equation:
2M+M=24, 3M=24, M=8
Remember that J=2M, so if M=8, J=16.
So Jeanine is 16 and Marc is 8

Answer:
Step-by-step explanation:
(39/7)(-12/5) = -468/35 = -13.37
Answer:
C
Step-by-step explanation:
They are both acute angles so the measurement cannot be above 90 degrees (right angle).
m<ADC is clearly smaller than m<AEC therefore m<AEC must be bigger than 28 degrees. C is the only option that fits
