Answer:
C
Step-by-step explanation:
3(3 + x) = 15 + x
Open bracket
9 + 3x = 15 + x
Collecting like terms
3x - x = 15 - 9
2x = 6
Dividing by 2
x = 6/2
x = 3
In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument.
if x is 8 then 12(8) + 12
12 times 8 is 96
96 + 12=108
the answer is 108
20+2N=52
now subtract 20 from each side, to get 2N alone
2N=32
now divide each side by 2
N=16
Answer:
320 cups of soup
Step-by-step explanation:
2/5= x/800
2/5 =.04
800*.04 =320 x=320
2/5 = 320/800
2/5 =0.4 is equivalent to 320/800=0.4
