8*5=40
2/5= 16/40
3/8= 15/40
1 16/40-15/40= 1 1/40
1 1/40 is the final answer.
I hope this helps!

You have to distribute!
6(x) = 6x and 6(-6)=-36
So now you have 6x-36=-3(-x+3)
Now do the same on the other side.
-3(-x)=3x -3(3)=-9
So now, 6x-36=3x-9
Combine the like terms:
Subtract 3x in both sides.
6x-3x=3x
Now: 3x-36=-9
Add 36 in both sides.
3x=27
Divide by 3 on both sides to get x alone.
3x/3= x 27/3=9
X=9
In this question, you're trying to find the unit rate in which the teacher can grade tests.
A unit rate is another word for "rate of change".
This means that we have to find how many tests the teacher could grade in 1 minute.
To find the unit rate, divide 18 by 15
18 ÷ 15 = 1.2
This means that Mr. Rivera can grade 1.2 tests in 1 minute.
Answer:
1.2 tests
Answer:
Mode=. 3,4
Mean= 21/6=3,5
Median= 3+4/2=5
Range=6-4=2
Step-by-step explanation:
1. Mode are numbers in between.
2. Mean add all number devide with the highest value.
3. Median are 2 middle number add them and divide them by 2.
4. Highest value subtract lowest value.
