C, and D. They’re parallel so they’re never going to cross.
Initial number = 36
Final number = 63
Change in number = 63 - 36
= 27
Percentage change = (27/36) * 100
= (3/4) * 100
= 3 * 25
= 75 percent
So the percentage change from 36 to 63 is 75%. I hope the procedure for solving is absolutely clear for you to understand. In future you can attempt such problems by following the procedure shown and you will require no further help from outside. Just be careful about the numerator and the denominator.
Using the first equation:
4x = y + 3 ---> y = 4x - 3
We then substitute this into the second equation:
7x - 9(4x-3) = -2 ---> 7x - 9x + 27 = -2 ---> -2x = -29 ---> x = 14.5
Answer:
B
Step-by-step explanation:
the perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width ) , then
P = 2(3
) + 2(
) ← distribute both parenthesis )
= 6
+ 2
= 8
