The graph shows the relationship between the amount of time that a backpacker hikes and the distance traveled.​
julsineya [31]

Answer:

The points represent that <u>5 miles </u> were hiked in <u>3 hours.</u>

Step-by-step explanation:

So, lets go over what we need to know.

The x coordinates is the time.

The y coordinates is the miles.

We have (3, 5)

This is (x, y)

x = 3, and y = 5. Considering what we know above, the time is 3 hours, and the miles is 5.

To fill in the boxes, it asks "Blank miles are hiked in blank hours"

We know 5 miles are hiked in 3 hours.

So the fill in for the first part is 5, and the fill in for the second part is 3.

Hope this helps!

Kassie recorded the favorite sport of students at her school. She surveyed 800 students. How many more students chose Baseball t
lisov135 [29]

Answer:

40 more kids chose baseball over basketball.

Step-by-step explanation:

The best way to go about this is to use benchmark percentages.

For baseball, 25% of 800 people chose that, so we can do 800/4 to get 200, so 200 students chose baseball

For basketball, we could do 800/5 but that isn't mental math, so we can do 10% of 800 is 80 and 80*2=160. So 40 more kids chose baseball over basketball.

Bess has $2.80 in quarters and dimes. The number of dimes is 7 less than the number of quarters. Find the number of quarters and
Nezavi [6.7K]

Answer:

3 dimes and 10 quarters

Step-by-step explanation:

If you add 7 dimes, then the number of dimes and quarters is the same, and the total increases to $3.50. A dime and a quarter have a value together of $0.35. Since there are equal numbers, the value $3.50 must be made up of some quantity of groups with a value of $0.35. That number of groups must be ...

... $3.50/$0.35 = 10

Thus, there are 10 quarters and 10-7 = 3 dimes.

_____

<em>Using an equation</em>

Let q represent the number of quarters. Then the amount Bess has is ...

... 0.10(q -7) +0.25q = 2.80

... 0.35q - 0.70 = 2.80

... 0.35q = 3.50 . . . . . add 0.70 . . . . . . . this should look familiar

... q = 3.50/0.35 = 10
