Lets say there are x blue marbles.
Purple marbles = 5 + 3x
Blue marbles = x
Total = 65
5 + 3x + x = 65
5 + 4x = 65
4x = 65 - 5 = 60
x = 60/4 = 15
Blue marbles = 15
65 - 15 = 50
There are 50 purple marbles.
I think it would be 6.3 [Plz don't kill me if I got this incorrect I tried-]
For no. 12 the car is not moving between 3 and 4
Deposit is 1/8 * $1200
So if you multiply 1200 by 1/8 you will get the answer.
or instead of multiply you just dived 1200 by 8 since its the same thing.
Deposit = $150
So if he's half of 60 that's 30.
If he's 4x his current age he was 120.
Half of 120 is 60.
I want to say he was 60.
Here's another theory of mine:
1*4=4
Let's go by 10s,
X(boy)*(stated in problem) =fathers age
10*4=40
20*4=80
30*4=120
C'Mon why would he, the father be 120
I sort of doubt 80
I don't doubt 40
Of course this is my thinking it may or may be correct but with Mathematical solving can it be determined.
