Answer:
I believe it's the 10 orange marbles.
Step-by-step explanation:
Their is a 45% chance that the orange marbles will be picked.
So, you add all them up (10 + 5 + 5 + 2)=22
10/22= 0.45%
Hope my answer has helped you!
So let’s make the smaller number x and the larger one y....
Set up your equation by following the words signaling mathematical operations from the question.
y = 8 + 4x
y + 4x = 40
Now let’s bring all variables to one side and solve the system if equations with elimination...
y - 4x = 8
y + 4x = 40
Add the equations:
2y = 48
y = 24
Plug the y-value into one of the original equations:
24 = 8 + 4x
16 = 4x
4x = 16
x = 4
And there you have it! The smaller number [x] is 4 and the larger number [y] is 24.
You have to think about what y and x can be equal to for you to get 12. (Hint: y is going to be a bigger number than x)
Ex: 3y-5x=5
Think: 3 x 10(y) - 5 x 5(x)= 5
So, y would be 10 and x would be 5.
So to find a tenth of a number, we divide the number by ten
Since we want to do the opposite, we multiply the number by ten
Therefore, .01*10 is .1
So, .01 is a tenth of .1
.1 is the answer
Hope this helped!! :D
= 24
