C.16.20
D.$24.30

Answers

Answer: D. $24.30

Step-by-step explanation:

I'm not completely sure.

The correct answer is C) $16.20


Here’s the math:
16.20 x 24= $388.80 (24 is the hours he worked in one day so he made $388.80 in one day)
388.80 x 12= $4665.60 (12 is the number of days he worked)
So Rick made $16.20 an hour

What value of w makes the equation 145 = w + 27 true?

Answers

Answer:

118

Step-by-step explanation:

In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.

Answer:

118

Step-by-step explanation:

145 = w + 27

Switch the + sign before the 27 and switch into a minus and move it to the other side.

145-27=w

145-27=118

w=118

First you set up the equation, 2x+15+3x-20=180

Then you add like terms, 5x-5=180

Add to both sides, 5x=185

Divide by 5 on both sides, x=37

The value would be 37, or X would equal 37. If you can, please mark this brainliest, so i can level up! thank you very much! :))

Answers

y2-y1
-------- OR you can do "rise/run"
x2-x1


Answer: -6/4

Answer:

-3/2

Step-by-step explanation:

To find the slope of the line, you need to use the slope formula.

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\[/tex]

Plug in the given points into the equation and solve for m.

[tex]m=\frac{-5 -1 }{6 -2 } \\\\m=\frac{-6}{4} \\m=-\frac{3}{2}\\[/tex]

The slope is -3/2.

Seth is comparing scenarios to determine which starting point he should get dropped off at to get him to school faster. Seth's house is 17 miles from school.



In which scenario does Seth start closer to school?


In which scenario does Seth travel at a greater speed, and what was the rate?

Answers

Answer:

In which scenario does Seth start closer to school?  

bus stop, 5 miles from home

In which scenario does Seth travel at a greater speed, and what was the rate?  

friend’s house, 2 miles every 3 minutes

The speed of Seth when he travels from the Bus stop will be faster. Because the speed is greater.

What is an average speed?

The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.

We know that the average speed formula is given as,

Average speed = Total distance / Total time

The speed of Seth when he travels from the Bus stop will be

Average speed = (8 - 5) / (6 - 0)

Average speed = 3 / 6

Average speed = 0.5 miles per hour

The speed at Seth when he travels from the Friend's house will be

Average speed = (8 - 4) / (9 - 3)

Average speed = 4 / 6

Average speed = 0.33 miles per hour

The speed of Seth when he travels from the Bus stop will be faster. Because the speed is greater.

A linear equation should have points that graph in a _____________ line.

Answers

A linear equation should have points that graph in a straight line.

Step-by-step explanation:

I hope it help !

A linear equation should have points that graph in a straight line.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear function is a function in which the slope remains constant.

Since a straight line has a constant slope thus it will represent the straight line.

Hence "A linear equation should have points that graph in a straight line".
