Hello from MrBillDoesMath!
Answer:
x = 3
Discussion:
Remark: if Tito solved the equation why didn't he tell you what the solution was ? ); Guess I'll have to do it myself....
2(3x+5) = 22 + 5x - 3x => 2(3x+5) = 6x + 10 and 5x-3x = 2x
6x + 10 = 22 + 2x => subtract 2x for both sides
6x - 2x + 10 = 22 => subtract 10 from both sides
4x = 22-10 = 12 => divide both sides by 4
x = 12/4 =3
Thank you,

Answer:
i think 30 minutes
Step-by-step explanation:
if you put twice as many pipes it should cut time down by half.
Y = -4x - 2
P (-16, -11)
a = -4, b = 0, c = -2
m = -a/b
m = -(-4)/(-2)
m = 4/(-2)
m = -2
y-yo = m(x-xo)
y-(-11) = -2[x-(-16)]
y+11 = -2(x+16)
y+11 = -2x-32
2x+y+11+32 = 0
2x+y+43 = 0

15(3p+4r)
Step-by-step explanation:
45p + 60r
factor out 15
15(3p+4r)
Answer:
y-4=3/2(x+4)
Step-by-step explanation:
If you plug the numbers into the equation (y-y1=m(x-x1)), you get y-4=3/2(x+4).
HOPE THIS HELPS
