Answer:
98
Step-by-step explanation:
Average is the sum of all data points divided the number of data points.
In this specific situation, the average test score, 91, is equal to the sum of Molly's four individual test scores divided by the number of test Molly had, 4.
(( 86 + 87 + 93 + x) / 4) = 91
86 + 87 + 93 + x = 91/4
86 + 87 + 93 + x = 364
x = 364 - 93 - 87 - 86 = 98
Answer:
I believe the answer would be 1,706.1
Step-by-step explanation:
Since the problem is a fraction, it would be easier to covert it to a decimal. This is made simple since the fraction is out of ten. Now, the number should look like this: 36.3
Now let's do long division.
Now we have answer of 1706.1
We have one more step. Since there is one number behind the decimal point in 36.3, we have to put one number behind the decimal point in our answer.
As you can see in the last picture, we have 1,706.1.
I hope you understand after I have explained. If you have any other troubles, tell me.
