Answer:
5:4
Step-by-step explanation:
There are 12 inches in one foot, so there are 24 inches in 2 feet.
Therefore, the ratio that compares 30 inches to 2 feet is the ratio that compares 30 inches to 24 inches.
This is

Simplify it:

So we need to find the inequality, Simple!
So we only have 5 dollars. That we cannot change.
But the snadwich, however, we can change how much we buy. But this problem is asking us how many we can buy. So that is an x. So far, we have 2.25x.
Then we have to use the inequality sign 'less than or equal to' because we can buy less or equal to 5 dollars.
So the equation is

Then we solve by isolating the x. We divide 2.25 both sides then we get
I would make the equation have both of your variables on the same side:
0.1x+y=1
Then I would use the cover-up method and say that
x-intercept= 10
y-intercept= 1
*Cover-Up Method: If you were finding the X-intercept, you would just ignore the y variable and divide your whole number by x.
In this case the whole number is 1. 1/0.1=10
Vice Versa with finding the Y-intercept
Probability of getting heads: 1/2
Probability to get 2 heads out of three tries is: 1/8
Work: 1/2 x 1/2 x 1/2 = 1/8
