Answer:
x = -9
Step-by-step explanation:
4x+10=-26
Subtract 10 from each side
4x+10-10=-26-10
4x = -36
Divide each side by 4
4x/4 = -36/4
x = -9
Answer:
x+4=36
Step-by-step explanation:
you would subtract 4 on each side
x+4=36
-4 -4
x=32
Facctore each
5y^2=5*y*y
80=5*2*2*2*2
lcm of those are
5
5(y^2-16)
we can factor this difference of 2 perfect squares
5(y-4)(y+4)
y+4 is the other one
so the lcm is 5y^2-80
83.333... %
The reason for this is because 15 divided by 18 is 0.8333... , so 0.8333... x 100 = 83.333... percent.
