Answer:
12x=10(25+x)
Step-by-step explanation:
Jim's rate=x
Pete's rate=y
Jim and Pete lays the same number of tiles.
So we have,
12x=10y
Pete's can lay 25 more tiles than Jim per hour
We have
y=25+x
Substitute y=25+x into 12x=10y
12x=10y
12x=10(25+x)
12x=250+10x
12x-10x=250
2x=250
x=250/2
=125
x=125
12x=10(25+x) is the equation used to find the rate that Jim can lay tiles

Answer:
-6
Step-by-step explanation:
1) combine all like terms
(bring 3q to the left and 11 to the right so you can combine the like terms)
(doing that will make 3q negative and 11 negative since your moving them so their sign changes as well)
8q-3q=-19-11
5q=-30
Q=-6
Hope this helps
