Step-by-step explanation:
This is a question to use proportions on.
3/4 cups 1 cup
/ =
3 cups x
Cross multiply
3 cups = 3/4x
multiply both sides by 4/3
4=x
Answer:
9.5 minute
Step-by-step explanation:
500 - 25 = 50x
x = 
x = 9.5 minute
We just need to subtract the total miles he has already rode from the total miles of the path.
12.25-11.5
0.75
So, he must bike 3/4 miles to reach the end.
The ratio is 1:20 so if you need to go up 2.5 inches you need to travel 2.5x20 inches horizontally.
2.5x20=50 inches.
Answer: 4x+15≥20
Step-by-step explanation:
To find the inequality, we can break down the sentence.
The first part says the sum of a number times 4 and 15. Let's split this apart. We begin with "the sum of". This tells us that we will be adding two things together. The first is a number times 4 and the second is 15. Let's use x for the unknown number. Therefore we would have 4x+15.
The last part is at least 20. This means the sum has to be 20 minimum. So the inequality we use should be greater than or equal to.
Therefore, the inequality is 4x+15≥20.
