Growth because “appreciate” 6% per year
Initial amount = 130000

130000(1+0.06)^x
Hope this helps!
X=y-2
2y=5x-17
Substituting for x into the second equation, we find
2y=5(y-2)-17
2y=5y-10-17
-3y=-27
y=9
So x=7
Thus, the two numbers are 7 and 9.
(5•4)-8 the answer is 12 because 5 times 4 is 20. Then 20 minus 8 is 12.
