Answer:
C. - 132x + 43y
Step-by-step explanation:
10x + 41y - 142x + 2y
Rearrange and put like terms together.
10x - 142x + 41y + 2y
= 10x - 142x
= - 132x
= 41y + 2y
= 43y
Now put all values together.
-132x + 43y

Step-by-step explanation:
12) Decrease in miles = 22,250 - 14,500 = 7750 miles
= 34.83%
13) Decrease in speed = 40 - 25 = 15 mph
= 37.5%
Answer:
20 years
Step-by-step explanation:
We start by writing an exponential equation;
FV = PV( 1 + r)^t
FV is the future value = 1,000,000
PV is present value = 372,000
r is rate = 5% = 5/100 = 0.05
t is time which we are looking for
1,000,000 = 372,000(1 + 0.05)^t
1.05^t = 1,000,000/372,000
1.05^t = 2.688
t ln 1.05 = ln 2.688
t = ln 2.688/ln 1.05
t = 20 years
