Answer:
(a) = 0.22 hours per dollar, (b) = 8.33 minutes per mile
Step-by-step explanation:
<u>(a): 4/18</u>
0.22 hours per dollar
<u>(b): 25/3</u>
8.33 minutes per mile
Answer: (a) = 0.22 hours per dollar, (b) = 8.33 minutes per mile
Answer:
Please Find the solution below
Step-by-step explanation:
Let us say the two equations are
x+y=5 --------------(A)
x-y=1 -------------(B)
Let us solve them for x and y by adding them
2x=6
x=3
Hence from (A)
3+y=5
y=2
Hence our solution is
x=3, y=2
Adding same number to equation (A) say 2 we get
x+y+2=5+2
x+y=5+2-2
x+y=5
Hence equation remains the same while adding same number to each side.
Same thing happens if we add same number to equation (B)
Hence we draw the conclusion that the solution remains the same if same number is added to each side of the original equation.
