Answer:
Step-by-step explanation:
p and h are number of plumbers and helpers, respectively.
Twenty workers earn a total of $2600
p+h = 20
h = 20-p
160p + 100h = 2600
160p + 100(20-p) = 2600
60p = 600
p = 10
h = 20-p = 10
Ten plumbers and ten helpers.
All you have to do is multiply them all.
3*3*4*2=72
See the denomenators
x^2 and 5x
factor each
x^2=x*x
5x=5*x
lcd=5*x*x or 5x^2
the factions would be 35/5x^2 and 7x/5x^2
