Answer: 4/3 hours or 1 1/3 hours
Step-by-step explanation:
From the question, we are told that two mechanics, Martin and Gordon, are working on your car. Martin can complete the work in 4 hours, while Gordon can complete the work in 2 hours.
Since Martin can complete the work in 4 hours, that means in 1 hour, he will do 1/4 of the work.
Since Gordon can complete the work in 2 hours, that means in 1 hour, he'll do 1/2 of the job.
When they both work together, we will add their fraction of work done in one hour together. This will be:
= 1/4 + 1/2
= 3/4
This means that both of them will do 3/4 of the job in one hour. Then to get the time taken to get the whole job done, we divide 1 by 3/4. This will be:
= 1 ÷ 3/4
= 1 × 4/3
= 4/3 hours
= 1 hour 20 minutes.

Answer:
13.4
Step-by-step explanation:
(9x+2) 119 to solve for x you need to isolate it so subtract 119 so the equation would look like this (9x+2) = -119. Once you do that you are going to subtract 2 from both sides of the equation (9x)= -121. And now you divide by 9 and you have your answer x= 13.4.
Answer: 2a^2+22a+−1
Step-by-step explanation:
Let's simplify step-by-step.
2a^2−5a+(9)(3)a−1
=2a^2+−5a+27a+−1
Combine Like Terms:
=2a^2+−5a+27a+−1
=(2a^2)+(−5a+27a)+(−1)
=2a^2+22a+−1
Answer:
The maximum number of miles they can travel is 6 miles.
Step-by-step explanation:
Because of the fix charge of $2, the amount of money left for the rest of the trip is $18. In order to find how many miles $18 cover when the cab charges $3 per hour, 18 is divided by 3. 18/3=6.
