Using a proportional relationship, the ordered pair that is a solution if x represents the number of days that a library book is late and y represents the total fee is:

(3, 0.9).

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

For this problem, each day, the free is increased by $0.3, hence the constant is k = 0.3 and the function is:

y = 0.3x.

Then after three days, the total fee is:

y = 0.3 x 3 = 0.9.

And the ordered pair is:

(3, 0.9).

It took a car 5 days to travel 2853 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per

Nat2105 [25]

Answer:

<u>24 miles per hour</u>

Step-by-step explanation:

First we need to convert days to hours. Since there are 24 hours in one day we need to multiply 5 by 24

$5*24=120$

This gives us 120 hours. Now we need to divide the total miles by the total hours

$2853/120=23.775$

Finally we need to round to the nearest mile per hour/ones digit. When rounding, remember if it is 4 or below you round down, and if it is 5 or about you round up.

23.775 - 5 is high so round up

23.78 - 8 is high so round up

23.8 - 8 is high so round up

24 is the final answer

Otto used 6 cups of whole wheat flour and x cups of white flour in the recipe. What is the equation that can be used to find the

RoseWind [281]

Well, there are $x$ amounts of white flower and 6 cups of wheat flower.

So the total flower is $x+6$

Given that $y$ is the total, the equation you would use is:
$y=x+6$

The constraints are as follows:
y can only be $\geq$ 6

And if y=0, x would have to be -6 (which is impossible)
