Answer:

13

Step-by-step explanation:

a parallelogram has sides that are parallel to the opposite side. This means that y + 7 is going to be parallel to 20.

Two opposing sides of a parallelogram are parallel and equal

You know that the length of both of the sides is equivalent because the other set of opposing lines is also parallel (you can think of it as cutting off the line segment of y+7 and 20 at the same length. )

this means that we can set up the equation to find y as:

y + 7 = 20

then, you can proceed to find y by isolating it:

y + 7 = 20 ; so therefore

y + 7    =    20

   - 7           -7

y           =     13

y = 13

So, the value of y is 13

Select the correct answer. What is the range of this data? (3,3, 0, 8, 7, 10, 2, 6, 12, 0}
Natasha2012 [34]

Answer:

D: 12

Step-by-step explanation:

The range is the difference between the largest value in the date minus the smallest value in the data.

In this set of numbers given, the largest value is 12 and the smallest value is 0

so: 12-0 = 12

The range of this data is 12
