Answer:

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

So, the value of y is 13

The difference of the quotient m and 9 and the quotient of n and 30

Zanzabum

Answer: (30m-9n)/270

First we start with m/9-n/30.

We multiply the denominators to get 270.

Then we multiply the numerators by the original denominators to get (30m-9n).

To check, we can use m=2, and n=4

2/9-4/30=4/45

(30*2-9*4)/270=24/270=4/45

61% of 180 ?

poizon [28]

First, when multiplying percents, you need to convert them to decimals. You convert percents to decimals by multiplying by 100 or moving the decimal two places to the left. Once you convert them to full decimals, you multiply the decimal by the number that you are getting the percentage from

61% of 180⇒.61×180=109.8 

5.1% of 81?⇒.051×81=4.131

 $16 \frac{1}{2}$ of 36?⇒16.5×36⇒.165×36=5.94

81% of 241⇒.81×241=195.21

76% of 600⇒.76×600=456

88% of 680⇒.88×680=598.4

37% of 481⇒.37×481=177.97

19.1% of 380⇒.191×380=72.58

41% of 321⇒.41×321=131.61

33% of 331⇒.33×331=109.23

Seven units long. The distance between 2 sides, in this example is 6, and -1. The distance between 6 and -1 is 7, so when you add units, you get 7 units.
