Isandro and Yvette each have a calculator. Yvette starts at 100 and subtracts 7 each time. Isandro on the other hand, starts at

zero and adds 3 each time. If they press the keys at the same time, will their displays ever show the same number? if so, what is the number?

Yvette = 100-7x
Isandro = 0+3x

0+3x = 100 - 7x
0+3x+7x = 100 - 7x +7x
10x = 100
x = 10
So on the 10th time they have the same number, which is 30.

A rectangle is 3 times as long as it is wide. The perimeter is 40 feet. Find the dimensions.
Digiron [165]
Basically, we take the parts and add together.
3 + 3 + 1 + 1 = 8.
So 40 divided by 8 = 5. So
the width is 5, and the length is 15. Hope it helps! :) If you could vote my answer as the brainliest, that would be awesome! :)

Equivalent fractions represent the same amount but the numbers are different.<br><br> True OR False
belka [17]
I believe this answer to be true. This can be said because 4/2 equals 2 as does 24/12. Both of those fractions equals 2 yet they are two completely different fractions. Please tell me if I was right lol.

nirvana33 [79]

Using the arrangements formula, it is found that there are 40,320 ways for these swimmers to finish.

<h3>What is the arrangements formula?</h3>

The number of possible arrangements of n elements is given by the factorial of n, that is:

A_n = n!

In this problem, there are n = 8 swimmers, hence they can finish arranged in 8! ways, that is:

A_8 = 8! = 40320

24 / 6 = 4

Mean = 4 for City A

City B- Mean:

Add all the numbers:

5 + 6 + 3.5 + 5.5 + 4 + 6 = 30

There are 6 numbers.

30 / 6 = 5

Mean = 5 for City B

B. MAD(Don't know this part)

C. Median

City A- Median:

There are 2 middle numbers.

They are 5 and 5.5

5 + 5.5 = 10.5

10.5 / 2 = 5.25

Median = 5.25 for City A

City B- Median:

The 2 middle numbers are 3.5 and 5.5

3.5 + 5.5 = 9

9 / 2 = 4.5
