Solve for x: 3x − 2 > 5x + 10. (5 points)
1) x > 6

2) x −6

Answers

Answer 1

Answer:

[tex]x<-6[/tex]

Step-by-step explanation:

[tex]3x-2>5x+10[/tex]

Add 2 to both sides

[tex]3x-2+2>5x+10+2[/tex]

Simplify

[tex]3x>5x+12[/tex]

Subtract [tex]5x[/tex] from both sides

[tex]3x-5x>5x+12-5x[/tex]

Simplify

[tex]-2x>12[/tex]

Multiply both sides by [tex]-1[/tex] (reverse the inequality)

[tex](-2x)(-1)<12(-1)[/tex]

Simplify

[tex]2x<-12[/tex]

Divide both sides by [tex]2[/tex]

[tex]\frac{2x}{2} <\frac{-12}{2}[/tex]

Divide the numbers: [tex]\frac{2}{2} =1[/tex]

[tex]=x[/tex]

Divide the numbers: [tex]\frac{-12}{2}[/tex]

Apply fraction rule: [tex]\frac{-a}{b} =-\frac{a}{b}[/tex]

[tex]=\frac{12}{2}[/tex]

Divide the numbers: [tex]\frac{12}{2} =6[/tex]

[tex]=-6[/tex]

[tex]x<-6[/tex]

Answer 2

Answer:

x < -6

Step-by-step explanation:

I just took the test. When you are dividing by a negative variable, flip the sign.

Which phrase best represents the following?
n
_ =7
5

Answers

Hey there!

“ n/5 = 7 ”

Usually whenever you have a letter value in mathematics it’s understood as a(n) UNKNOWN value; people label them as a invisible 1

~ FIRST: you have to MULTIPLY both of your SIDES by 5

1n/5 • 5 = 7 • 5

~ CANCEL out; 1/5 • 5 because that gives you a 1
~KEEP: 7 • 5 because it gives the value of your “n”

New equation: n = 7 • 5

7 • 5 = 35

Answer: n = 35 ☑️

Regular division problem: 35/5 = 7 so this makes it true!

Random fact; math actually repeats a lot.. so it can become easier for you to understand or tackle problems like this on your own!

Good luck on your assignment and enjoy your day!

A HARD DRIVE COST 225,plus 40 hours per hour

Answers

Y=40x + 225
Because x is your per hour cost.
225+40h=y
225 + 40x = 385
-225 -225
------- -------
40x = 160
x= 4

2x + y = -3
What’s the solution?

Answers

y= -3 - 2x because all you have to do is move the 2x over to have an x and a y on different sides, and in order to do that you do the opposite so since it is a positive 2, you subtract it and make it negative

5+3w+3-w combine like terms to simplify

Answers

Answer:

8 + 2w

Step-by-step explanation:

⇒ Change all signs to addition (subtraction is the same as adding a negative):

5 + 3w + 3 + -w

⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:

5 + 3 + 3w + -w

⇒ Simplify:

8 + 2w

Answer: 8 + 2w

Hope this helps! :)

The answer would be 8 + 2w because your combining like terms. You would have to add 5+3 to get 8. And combine 3w-w to get 2w

1. Pentagon MNPQR is shown on the coordinate grid. Pentagon MNPQR is dilated with
the origin as the center of dilation using the rule (x, y) - (x, y) to create pentagon
M'N'P'Q'R'. Which statement is true?

Answers

Answer:

B

Step-by-step explanation:

if its less than 1 it shrinks

The correct statement is; Pentagon M’N’P’Q’R is smaller than pentagon MNPQR because the scale factor is smaller than 1.

What is the scale factor?

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

If a polygon is dilated by a scale factor = k

Rule to be followed as;

(x, y) → (kx, ky)

Here, k = Scale factor

If 0 < k < 1, size of the image will be reduced.

Similarly, k > 1, size of the image will be enlarged.

We are given that Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.

Rule used for the transformation,

(x, y) → (1/4x, 1/4y)

Here, the scale factor through which MNPQR has been dilated is 1/4.

Since, scale factor is between zero and 1/4, size of M'N'P'Q'R' will be reduced.

Therefore, the size of pentagon M'N'P'Q'R' will be 1/4 smaller than pentagon MNPQR.

Option (2) is the answer.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

There are 10 seniors and 15 juniors in a gym class.

The total number of students will be given as,

Total students = 10 + 15

Total students = 25

Then the ratio of seniors to total students will be given as,

Ratio = Seniors / Total student

Ratio = 10 / 25

Ratio = 2 / 5

The ratio of seniors to total students will be 2: 5.
