<h3>
Answer:</h3>
4 miles per hour
<h3>
Step-by-step explanation:</h3>
Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.
Proportion
First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.
- This creates the proportion
So, the rate we are given is 12/3.
Unit Rate
To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.
- 12/3 equals 4
- 3/3 equals 1
So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.
Graph
Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.
Answer:
just add 2.5 to Lin's distance and 3 to Andre's distance. eventually you will reach a point where their values are the same. Then the hour next to it is the answer you are looking for
Step-by-step explanation:
390, because 10% of 1300 is 130 so 130 times 3 = 390
The number of bottles in the full box by solving the equation is 12.
<h3>How to form an equation?</h3>
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of bottles in the full box = x
Initial bottles = 9
Bottles in 3 full box = 3x
Bottles in 2 box in which number of bottles is x - 1 = 2(x-1)
Now,
Total bottles in refrigerator is 67
So,
9 + 3x + 2(x - 1) = 67
9 + 3x + 2x - 2 = 67
5x = 60
x = 12
Hence "The number of bottles in the full box by solving the equation is 12".
