Martha can buy 30 of each.

If we find the LCM (Least Common Multiple) of each number, it would look something like this:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
10: 10, 20, 30

The LCM would be 30.

The length and width of a rectangle are in a 3:5 ratio. The perimeter of the rectangle is 64. What are the length and width of t
Levart [38]

Hey there! I'm happy to help!

We know that the perimeter is 2L+2W. Le'ts plug in the values 3 and 5 from our ratio and see what our perimeter would be with that.

2(3)+2(5)

6+10

16

How can we get this 16 to 64?

64/16=4

So, we need to multiply this length and width by four to get 64 as our perimeter!

3*4=12

5*4=20

We can plug this into our perimeter equation

2(12)+2(20)

24+40

64

Therefore, our length is 12 and our width is 20.

Have a wonderful day! :D

Multiply the second equation's terms by 3. Solve for x.

Step-by-step explanation:

You will get:

2x+9y=28

9x-9y=42

Add them to get:

11x=70.

You can solve from there.
