Answer:
B=1 M=6 D=3
Step-by-step explanation:
the equations are 4M+4D+2B=38
M+D+B=10
2D=M
step two: 4M+4D+2B=38 (multiply 2nd equation by -4)
-4M-4D-4B=-40
4M AND 4D cancels out and your left with -2B=-2 B=1
then you take the first equation and subsitute the third equation for M
step three: M+D+1 =10 (SUBSITUTE B WITH 1)
M+D=9
STEP FOUR: take the last equation (M+D=9) and subsitute 2D=M
2D+D=9
3D=9
D=3
subsitute D=3 into 2D=M so you get 2(3)=M M=6
DOUBLE CHECK USE THE SECOND EQUATION
M+D+B=1-
6+3+1=10
Answer:
B: r =n/2
Step-by-step explanation:
Recondition only mean is that half of what the new is so recondition equals the new over half because recondition is half the price of the new
Because v represents the initial value of the car, the answer for the first section would simply be $21,300. The percent of change per year is between the parentheses (1.16 in this case). Since it is greater than one, the amount increases every year meaning it represents growth.
The answer is x >_ -2 and x >_ 7.
