Simplify (2+5-10) and then it's -3 and then (7x)(-3) = -21
5^-4 / 5^3
= 5^-1
= 1/5

10 days - 5 days = 5 days.
6 gliders - 3 gliders = 3 gliders.
They make 3 gliders in 5 days: 3/5 = 0.6 gliders per day.
y = 0.6x
The answer is A.
We can solve this by elimination, in order to do this we need to multiply the bottom equation by three to cross out the X
(x+5y=38)3 3x+15y=114
-3x+4y=95
3x+15y=114
then add the two equations together and the X will cancel out
19y=209
----- -----
19 19
y=11
then plug that in into one of the equations
x+55=38
-55 -55
x= -17
your answer is (-17,11)
