You also don't play with your DS anymore and have 11 games as well. You want to sell these to make space your room and help you save for a car. You know you won't get close to how much you spent originally but that's okay. You bought the DS for $125 and the games were $20 each. How much did you spend for the DS and 11 games total?

x=12 units bd= 10 units

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

the answer is 13/48
