Answer:
Step-by-step explanation:
3(x + 5) = 36
3x + 15 = 36
3x + 15 -15 = 36 - 15
3x = 21
3x/3 = 21/3
x = 7
Answer:it would be $894.30
Step-by-step explanation:
You would multiply 813 by .1 (10%) then add that (81.3) to the principal (813). That gives you the total cost
Answer: D
Step-by-step explanation:
Answer:
x = 25
Step-by-step explanation:
Mathematically, one of the properties of a parallelogram is that consecutive angles of a parallelogram are supplementary
What this means is that they add up to be 180
A and B are supplementary, and this means that their addition equals 180
Thus, adding A and B equals 180
2x -10 + 5x + 15 = 180
7x + 5= 180
7x = 180-5
7x = 175
x = 175/7
x = 25
