3 &amp; 4, And tell explanation<br><br> (P.S: Sorry for my sloppy handwriting)
Kazeer [188]
3) Altitude / Time = y2 - y1 / x2 - x1 = 30 - 60 / 6 - 3
 m = -30 / 3
 m = -10

In short, constant rate of change is y = -10x

b) Constant proportionality exists between two quantities, as the amount of changing in Altitude over fixed period of time is same (constant) for every instance. 

4) Sales / Day = y2-y1 / x2-x1 = 2,000 - 1,000 / 6 - 3
m = 1000 / 3
m = 333.3

a) In short, Constant relationship is y = 333.3x

b) Constant proportionality exists between two quantities, as the amount of changing in Sales over fixed days is same (constant) for every instance. 

Hope this helps!

I have 7200 bags of snickers. If the rest is Hershey’s and Twix is 2/3 of snickers, how many Hershey’s are there?
AveGali [126]

Answer:

Step-by-step explanation:

You have 7,200 bags of snickers

Twix is 2/3 that of snickers

Hershey's is ?

First you need to find out how much Twix you have.

You will need to multiply as a fraction: 2/3*7,200/1 (2 over 3 multiplied by 7,200 over 1)

Next multiply the two numerators together (numerators are the numbers on top of a fraction and the numbers on the bottom of the fraction are called denominators)

2 * 7,200 = 14,400

Next multiply the denominators together:

3 * 1 = 3

So now your fraction is 14,400/3 (14,400 over 3)

Now divide the denominator into the numerator:

14,400 divided by 3 = 4,800

So 2/3 of the 7,200 bags of Snickers equals 4,800 Twix

Now take away the Twix from the Snickers

7,200 - 4,800 = 2,400

So now all up you have:

7,200 bags of snickers

4,800 bags of Twix

2,400 bags of hershey's

=)
