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.
The correct answer is intersection point
When you find the solution, you actually find where the two lines cross on the coordinate system. It is the single point that works in all equations.
When you are determining the answer to the question, make sure you know to change the signs. The answer is - 7. 7
Answer:
Probability, eh?
Step-by-step explanation:
To figure out how likely an event is, we just put the number of the blue bands over the total number of 'other' bands.
Pretty easy!
(or do you want it in percent?)
%
(I remember there was a weird notation for these things, but I forgot it)
It is unlikely he will choose a blue band, as it is much more likely he will choose a 'other' band.
Remember, the smallest number for an event will make it the most unlikeliest to happen out of all the others.
Hope this helps!

5(11x-5)=85
55x-25=85
+25 +25
55x=110
