Answer:

B.30

Step-by-step explanation:

The difference is subtracting so we have

y-x=-8

We know one is 22 so we replace y with 22:

22-x=-8

Now all we need to do is solve:

Subtract 22 on both sides:

-22+22-x=-8-22

-x=-30

Divide by - or -1 on both sides:

-x/-1=-30/-1

x=30

So the "number" is 30

Hope this helps!

Mademuasel [1]

<h3>Answer: 72 degrees</h3>

n = 5 is the number of sides in a pentagon

360/n = 360/5 = 72 is the measure of each exterior angle of the regular pentagon. It has to be a regular polygon or else you could have some exterior angle measures that are different. A regular polygon has all sides equal to one another, and it also has all angles equal to one another.

Sam buys 6 pencils and 5 erasers for a total cost of $1. 60. Sally buys 3 pencils and 3

Ipatiy [6.2K]

One eraser costs 20 cents.

Let p = the amount of pencils and e = amount of erasers.

Equation 1. 6p + 5e = $1.60
Equation 2. 3p + 3e = $0.90

If we times equation 2 by 2 to get 6p + 6e = $1.80 and call it equation 3 we can minus equation 1 from it to get equation 4.

Equation 3. 6p + 6e = $1.80
Equation 1. - ( 6p + 5e = $1.60 )
Equation 4. e = $0.20

Therefore an eraser is 20 cents.
Hope that helps.
