If he uses 1 quarter, he has 40 cent left to make.He can do that in two ways, by using 2 dimes andall four nickels, or all 3 dimes snd 2 nickels.That's 2 ways.
If he uses both quarters, he has 15 cent left to make.He can do that in two ways by using 1 dime and 1 nickel,or no dimes and 3 nickels.That's 2 more ways.    So there are four ways to make 65 cents.

Answer:

4 ways

Step-by-step explanation:

Given that A vending machine accepts​ nickels, dimes, and quarters.

Purchase amt = 55 cents

Coins available = 4 nickels, 3 dimes and 2 qrs

Values                    5             10                 25

To give 55 cents, there are these possibilities

(2 qrs, 1 nickel)  or (1 qr, 2 dimes),  or (1 qr, 1 dime, 2 nickels) Or (1 qr, 4 nickels)

If he does not use a quarter, total value of dimes and nickels = 30+20 = 50 only.

Thus he has to use atleast one quarter.

Hence there are only 4 ways to do this

Will give brainliest!!!!<br>Explain how solving -7y &gt; 161 is different from solving 7y &gt; -161.
Jlenok [28]

To solve -7y > 161, we divide both sides by -7 and we get y < -23. The inequality sign flipped because we divided both sides by a negative number.

To solve 7y > -161, we divide both sides by 7 and it leads to y > -23. The inequality sign does not flip in this case, because we are not dividing both sides by a negative number.

The similarities is that we end up with -23 on the right side, but the inequality signs are different.

PLEASE HELP!!!!
Semmy [17]
You should put 4 as x, -3 as y and a as slope to make an equation :
- 3 =  a \times 4
then you can find the slope and the correct equation of the line :

the slope is :
- 3 = 4a \\ a =  \frac{ - 3}{4}
so the equation of the line will be
y =  \frac{ - 3}{4}  x
D is true
hope this helps
