Answer:
$57.60
Step-by-step explanation:
Marcus lays a slab of concrete in 3 hours. Tony lays the same size slab in 2 hours. The number of hours used by both men will be:
1/3x + 1/2x = 1
2x + 3x = 6
5x = 6
x = 6/5 = 1.2 hours.
The cost of labor will be:
= 1.2 hours × $48
= $57.60
X = 10 opposite sides are equal to eachother

then -3 times x which is -3x
then -3 times 11 which is -33
