Answer: B
Step-by-step explanation:
The number of hours it took him to complete the job is; Choice B: 20 + 25x = 282.50; x = 10.5 hours
According to the question;
The one-time service fee of the plumber is; $20
The plumber's hourly rate is; $25 per hour.
The total bill after working on toilet and bathroom came to; $282.50
The expression which represents the plumber's charge is therefore;
20 + 25x = 282.50where, x = number of hours to complete the job.
Therefore, to find x;
25x = 282.50 - 2025x = 262.50x = 262.50/25x = 10.5 hours.
The total number of hours it took him to complete the job is; 10.5 hours.

How do solve this question? Find an equation of a line parallel to the given line and contains the given point. Write the equation in slope–intercept form. With the equation 2x + 5y= -10 point (10, 4).
Answer:
y = -2/5 x + 8Step-by-step explanation:
First we need to find the slope of the given line;
Given the line 2x + 5y= -10, we need to write it in standard form of y = mx+c
Make y the subject of the formula;
2x + 5y= -10
5y = -2x-10
y = -2x/5-10/5
y = -2x/5 - 2
Hence the slope of the line m = -2/5
Since the equation of the line we need is parallel to this line, hence they will have the same slope.
The slope of the required line = -2/5
Get the intercept;
Substitute the point (10,4) and m = -2/5 into the equation y = mx+c
4 = -2/5(10)+c
4 = -4 + c
c = 8
Get the required equation;
y = mx+c
y = -2/5 x + 8
Hence the equation of a line parallel to the given line and contains the given point is y = -2/5 x + 8

Step-by-step explanation:
To find the slope, use rise over run. Go up from the y-intercept and over until you hit another exact point.
To find the y-intercept, just find the point that is on the y-axis.

Which proportion would be used to solve the following problem. The proportion of turtles to alligators at the reptile park is 5:9. Since Beth counted 45 turtles, how many alligators are there?
Answer:
befor i go im trynna love you baby hopefully e
Step-by-step explanation:
Answer/Step-by-step explanation:
There are 81 Alligators.
The original equation was 5:9. Since the 5 turtles have been scaled up(multiplied by) 9 times. The rate for alligator will be multiplied by 9.
45 ÷ 5 = 9
9 x 9 = 81
5:9 x 9 = 45:81

Step-by-step explanation:
In order to find slope when you have two ordered pairs, you use this equation: (y2-y1)/(x2-x1)
In this case, when you plug them in, you get (49-7)/(42-6), which is 42/36, which is 7/6.

Find the equation of the line that is perpendicular to y = -2x+ 6 and passes though the point (-4,2).
Answer:
y= 1/2x + 6
Step-by-step explanation:
when making a perpendicular equation, flip the slope.
Answer:
y = 1/2x + 4
Step-by-step explanation:
The slope of the perpendicular line will have the complete opposite slope.
The perpendicular slope is 1/2x.
To get the slope I just got the opposite sign and reciprocal of -2.
NOW plug in (-4,2) to find the y-intercept
2 = 1/2(-4) + b (b represents y-intercept)
2 = -2 + b (add 2 on both sides)
4 = b
y = 1/2x + 4 is the final equation
