What you mean is this a question I don’t understand it
Answer: 6
Step-by-step explanation: 36 divided by 6 equals 6
48 divided by8 is 6
common factor is 6
7 unit to the left, means it is 7 less than -1.
-1-7 = -8
Ans: -8
D = mV + C , ( compare this to your familiar y = mx + b)
when V=40, D=150
150 = 40m + C **
when V=54, D=192
192 = 54m + C ***
subtract ** from ***
42 = 14m
m = 3
sub into ** , 150 = 120 + C
C = 30
so you have D = 3V + 30
sub in your given value of V
