Answer: A
Step-by-step explanation:Greg
Enable M = Mary's age now So Mike's age is 3M 3M + 4 = 2 (M + 4) = 2M + 8 Now, subtract 2M from the two factors. then you definitely have: M + 4 = 8 or M = 4 examine: Mike is now 12. In 4 years, Mary would be 8 and Mike would be sixteen.
Answer:
7x + 34 = 90
-34 -34
7x = 56
Divide by 7 on both sides:
X = 8 degrees
A right angle equals 90 degrees so that must mean angle 7x + 34 must equal to 90 so we solve for x.
A triangle equals = 180 degrees
A quadrilateral equals = 360 degrees
A right angle equals = 90 degrees
A straight line equals = 180 degrees
