Answer:
Two students will take 24 minutes to wash the car.
Step-by-step explanation:
In this case we can apply a rule of three to find out the time that will take for the students to wash the car. This has to be done such as:
3 students -> 16 minutes
2 students -> x minutes
3/2 = 16/x
But in this cases the problem states that this variables are inversely proportionate, which means that if there's less students washing the car they will take more time to finish the job. So we need to invert one of the fractions before computing the result.
3/2 = x/16
2*x = 3*16
x = 48/2 = 24 minutes.
Two students will take 24 minutes to wash the car.
Answer:
0.6b - 3c
Step-by-step explanation:
Multiply 0.2 and 3b
0.2 x 3b = 0.6b
Then multiply 0.2 and 15c
0.2 x 15c = 3c
We can't add these, 3c and 6b because they have different letters.
different letter vs. different letter =
don't add
different letter vs. normal number like 5 =
dont add
same letter vs. same letter =
add
normal number vs. normal number =
add
This all goes the same for dividing, subtracting, and multiplying
I hope this helped! :)
C - 0
If you put 0 into the graph (as an x value), your output would be 0.
Answer:
7 9/14
Step-by-step explanation:
The girls ate 8 1/7 of a pie, so we mark G=8 1/7
The boys ate 1/2 of a pie, so we mark B=1/2
The girls ate the more pies, so we do this:
G-B
We plug the G and the B in, and it is 8 1/7-1/2
We change it to the common denominator, which is 14. We have 8 2/14- 7/14
we take a one and add 14 to 2 and we have this:
7 16/14-7/14
and that equals 7 9/14
