Answer:
16.67
Step-by-step explanation:
Solution for 90 is what percent of 540:
90:540*100 =
(90*100):540 =
9000:540 = 16.67
Assuming that X represents the number of hours worked and f(x) the number of cars washed, the equation would be f(x)=11x+14x.
The 11x represents the number of cars washed by Arianna in x number of hours and the 14x represents the number of cars washed by Matthew in x number of hours. You add the two because they are each washing their own car at their own pace but working on one lot.
The number of solutions of the equations can't be determined.
<h3>How to illustrate the information?</h3>
It should be noted an equation shows the relationship between the variables. It should be noted that the question is to find the number of solutions.
From the information, 3(5x + 2) = 15x
15x + 6 = 15x
Collect like terms
15x - 15x = - 6
0 = -6
Therefore, it can be see that the friend is incorrect as the number of solutions of the equations can't be determined.
