Given:
4/5 of a pie left after their family picnic.
Each slice of pie was 1/15 of the total pie.
To find:
The number of remaining slices of pie.
Solution:
Let x be the number of remaining slices of pie.
Part of total pie in one slice = 
Remaining part of total pie in x slices = 
According to the question, 4/5 of a pie left after their family picnic.

Using cross multiplication, we get


Divide both sides by 5.

Therefore, the remaining number of slices of pie is 12.
Answer:
the cost of one sweater is $40
Step-by-step explanation:
The computation of the cost of the one sweater is shown below;
Let us assume the sweater be x
And, the pant be y
Now the equations are
2x + y = $120 ..............(1)
x + 2y = $120................(2)
Now multiply by 2 in equation 1
4x + 2y = $240
x + 2y = $120
3x = $120
x = $40
Hence, the cost of one sweater is $40
Answer:
16
Step-by-step explanation:
Rearrange this data set in increasing order: -6 -5 -3 -1 6 10
The range is the difference between the highest value and the smallest:
10 - (-6) = 16
