Step-by-step explanation:
put -5 into x
then
3*-5 is -15 (-2)
-17 is your answer
Answer:
y/x= -8/-2= 4 => when y=32 => 32/x=4 => x=8
Are you trying to solve for x and y?
y=2x+1; x+2y=17
sub in one variable in the other equation.
x+2(2x+1)=17
x+4x+2=17
5x=15
x=3
now that you have x value, plug into the original equation to find y and check with the other.
y=2(3)+1 = 7
x+2y=17 = 3 + 2(7) = 17 ; 17=17
72% can also be written as 0.72, so take 0.72 x 45 = 32.4
Subtract 32.4 from 45 45 - 32.4 = 12.6 You need 12.6 renewals in 5 days.
