7 + 5x = 2x + 25
step by step pls:(

Answers

Answer:

x = 6

Step-by-step explanation:

7 + 5x = 2x + 25

first subtract 7 from both sides to isolate 5x on the left

5x = 2x + 18

then subtract 2x from both sides to isolate all of the x terms to one side

3x = 18

then divide 18 by 3 to solve for x

x = 6

Find the inequality represented by the graph

Answers

Answer:

y ≥ 1/2x

Step-by-step explanation:

Given the following inequality, we know that y must be greater than or equal to x because the line is not dashed, and is shaded above the line.

Now to find the equation just pretend that this is just a normal linear equation, and solve for the equation.

So since the y intercept is 0, and there is a rise of 1 for a run of 2 or 1 unit up every two units to the right, the corresponding linear equation is y = 1/2x.

Now since this is an inequality where y is greater than or equal to x.

y = 1/2x → y ≥ 1/2x

What is the image of the point (7,-5) after a rotation of 270° counterclockwise
about the origin?

Answers

Answer:

(-5, -7)

Step-by-step explanation:

if you rotate the point by 270 degrees counterclockwise, you get (5,-7) and I'm guessing image is another way to say reflection so after it is reflected then the point would be (-5,-7)

(-7,5) is the correct answer because 270 degrees counter clockwise is y,-x

Which simplified equation is equivalent to the equation shown below? 4x + -3 -9 +4x=6​

Answers

Answer:

x + x = 4.5 or x = 2.25 is the answer or the value of x.

Step-by-step explanation:

4x + -3 -9 +4x=6​

4x + 3 + 9 + 4x=6 + 3 + 9

4x + 4x = 18

4x/4 + 4x/4 = 18/4

x + x = 4.5

77th term for -10,-8,-6

Answers

9514 1404 393

Answer:

 142

Step-by-step explanation:

The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...

  an = a1 +d(n -1)

  an = -10 +2(n -1) = 2n -12

Then the 77th term is ...

  a77 = 2(77) -12 = 154 -12

  a77 = 142

The 77th term is 142.

You have 5814 meters of rope you need to cut into 27 sections how many 27 meters secton of rope will you be able to create and how much rope will be left over as waste

Answers

Answer:

215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left

Step-by-step explanation:

we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:

you have to divide 5,814 meters by 27 meters = 215.333

that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)

A college information pamphlet provides some statistics about the students and the professors to help high school seniors decide if they want to attend the college. The pamphlet lists the ratio of students to professors as 18 to 1. If there are 702 students at the college, how many professors are there?

Answers

Answer:

39

Step-by-step explanation:

Setting up your problem and solving:

In the question it says the ratio is students to professors right? So 18 to 1.

Write that down: Students to Professors is 18 to 1.

We know that there are 702 students in that college correct?

Write that down: 702 students in the college

We are trying to find how many professors there are so...let's do that.

Number 1:

Set your equation: have your fraction bar and equal sign like this: --- = ---

On the top, we have 1 so... 1/? = ?/?

On the other top we have the x...: 1/? = x/?

Why? Because we do not know the total of professors there are so that is X.

We put the number 1 on the other side because we know that there is only 1 out of 18 professors to students.

Number 2:

On the bottom, we will have 18...: 1/18 = x/?

On the other bottom we have 702...: 1/18 = x/702

Why? Because we know that there is a total number of 18 to 1 students on the ratio and a real total of 702 students.

Number 3.

Now you have your equation set up: 1/18 = x/702

The next step is yours: cross multiple, divide on the bottom or top or find the comparison.

I'm going to divide by the bottom okay? so.. 18/702

Set that up.

(702/18)

702/18 is 39!

SO in the end there is a total of 39 professors!

'x=39'
