First we need to know how many miles per hour they drove the first time. This would be found by division. 168/3.5=48
Then we need to add 5 miles per hour for the average.48+5= 53
Next we need to multiply 2 1/4 by the new miles per hour 53*2.25=119.25
After that we need to know how many miles they drove 119.25+168=287.25 miles.
Finally to get an improper fraction we need to change 287.25 miles to it.
We already have 1/4 for .25 so we multiply 287 by 4 and add it to the 1/4 we already have and it makes it out to be 1149/4

Answer:
<h2>(0,1) and (2,5).</h2>
Step-by-step explanation:
The graph of the inequality is attached.
Remember, a solution of an inequality is a point on the shaded region. Also, it must satisfy the inequality expression
From the graph we know the possible answers are (0, 1) and (2, 5), let's prove it.
<h3>For (0, 1):</h3>
Which is true, so (0, 1) is solution.
<h3>For (2, 5):</h3>
Which is true, so (2, 5) is solution.
Therefore, the solutions are (0,1) and (2,5).
Answer:
The change is increasing with a percentage of change of 64%
Step-by-step explanation:
Since we have the present grater than the original, then the change is increasing
Secondly, we want to calculate the percent of change
Mathematically , that will be ;
(present - original)/original * 100%
= (90-55)/55 * 100%
= 35/55 * 100% = 63.63 which is approximately 64%
