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

Answer:
2640 feet
Step-by-step explanation:
Let's make a proportion using this:
feet/seconds=feet/seconds
We know the car travels 88 feet in 2 seconds.
88/2=feet/seconds
We don't know how many feet the car can travel in 1 minute (which is equal to 60 seconds).So, the car travels x feet in 60 seconds.
88/2=x/60
We want to solve for x. To do this, we have to get x by itself. x is being divided by 60. Multiply both sides by 60, because multiplication is the opposite of division.
60*88/2=x/60*60
The 60s on the right will cancel, so we are left with
60*88/2=x
60*44=x
2640=x
The car can travel 2640 feet in 1 minute.
Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6
=(−n + 4n) + (−4 + 6)
=3n + 2
