Answer:
The value of M would be 18
Step-by-step explanation:
It's 18 because if we do 5 x 14 x 18 it would give us 1,260 cm
<span>2x+14y=-108
</span><span>63x+14y= 14 (multiply the second equation by 7 and subtract)
_____________
-61x=-122
x=-122/-61
x=2
2(2)+14y=-108
4+14y=-108
14y=-112
y=-112/14
y=-8

Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
You can rewrite this as A - 25 = 75. You always can cancel adding a negative into just subtracting, and although it may not seem important yet, it’s a good habit to get into for further algebra.
A = 100.
C = 3.5t....when t = 15
c = 3.5(15)
c = 52.50 <==
