Marko has 45 comic books in his collection, and Tamara has 61 comic books. Marko buys 4 new comic books each month and Tamara buys 2 comic books each month. After how many months will Marko and Tamara have the same number of comic books?

hi

Write 2 equations, multiply amount bought per month by number of months and add to the starting values :

Marko = 45 + 4M

Tamara = 61 + 2M

Set the equations equal to each other and solve for number of months:

45 + 4m = 61 + 2m

Subtract 45 from both sides:

4m = 16 + 2m

Subtract 2m from both sides:

2m = 16

Divide both sides by 2:

m = 8

8 months

The length of each side of square is 5ft.

Step-by-step explanation:

Given:

A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.

The area of the triangle is 7.5ft squared.

Now, to find the length of each side of square.

Now, we need to get the area of the square first:

Area of combined figure - area of triangle = area of square.

32.5 ft squared - 7.5 ft squared = 25 ft squared.

So, area of square = 25 ft squared.

Now, by putting the formula for getting the length of each side:

Let the side = a.

Area of square = 25 ft squared

Area of square = a²

Using square root both sides we get:

So, the side = 5 ft.

Therefore, the length of each side of square is 5ft.
