The equation to determine the number of hours worked by the plumber is 190 = 35 + 50x and the number of hours is 3.1 hours option (A) is correct.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Jerald is having drain issues at his home and decides to call a plumber.
The plumber charges $35 to come to his house and $50 for every hour they work.
Let x be the number of hours:
190 = 35 + 50x
50x = 155
x = 3.1 hours
Thus, the equation to determine the number of hours worked by the plumber is 190 = 35 + 50x and the number of hours is 3.1 hours option (A) is correct.

Answer:
4 gallons with 65% soultion
Step-by-step explanation:
1. add the number of gallons together to find the total amount of the liquid in this case 4 gal.
2. Find the amount of solution in each part. In this case from the 3 gal there is 2.4 solution and for the 1 gal its 0.2 solution. I found this by finding the percentage.
3. Next, add the amounts of solution together to get 2.6 solution in all.
4. lastly, caluculate how much percent 2.6 is out of the total 4 gals.When you do this in all you get 4 gal with a 65% solution.
The area of a trapezoid can be found with this formula:
Where b1 and b2 are the bases and h is the height.
If we plug in what we know we can solve for the height.
We know that b1 = 52, b2 = 42, and A = 1833. Let's solve.
