Make a system of equations and solve for each variable.

3m+8v=53
5m+2v=26

m= movie cost
v= game cost

multiply the bottom equation by 4(combination method)

3m+8v=53
20m+8v=104. Subtract

-17m = -51
m= 3

Plug back into one of the equations

5(3)+2v=26
15+2v=26
2v=11
v=5.5

m=$3
v=$5.5

How to write composite number till 25 in set builder form Pls help
dimaraw [331]

All the natural numbers which are not prime numbers are composite numbers as they can be divided by more than two numbers (1 and itself).

Example: factors of 12

12 ÷1 = 12

12÷ 2 = 6

12÷3= 4

12÷4 = 3

12÷6=2

12÷12 = 1

= {12,6,4,3,2,1}

Composite Number/ Its Factors

4 = {1,2,4}

6 = {1,2,3,6}

8 = {1,2,4,8}

9 = {1,3,9}

10 = {1,2,5,10}

12 = {1,2,3,4,6,12}

14 = {1,2,7,14}

15 = {1,3,5,15}

16 = {1,2,4,8,16}

18 = {1,2,3,6,9,18}

20 = {1,2,4,5,10,20}

21 = {1,3,7,21}

22 = {1,2,11,22}

24 = {1,2,3,4,6,8,12,24}

25 = {1,5, 25}

Hope it helps!
