m-18=n
This makes no sense this is my 3rd time asking this question

Answers

Answer 1

Answer:

m=18+n

Step-by-step explanation:

m + -18 = n            simplify

-18 + m = n            record the terms

-18 + 18 + m = 18 + n             solve

Combine like terms: -18 + 18 = 0,   0 + m = 18 + n,     m = 18 + n

Final answer: m = 18 + n

Answer 2

Answer:

IDK but here's what I have found.....

Step-by-step explanation:

Simplifying

m + -18 = n

Reorder the terms:

-18 + m = n

Solving

-18 + m = n

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + m = 18 + n

Combine like terms: -18 + 18 = 0

0 + m = 18 + n

m = 18 + n

Simplifying

m = 18 + n

It looks like an exponential function
I think it’s exponential because there isn’t a cube root or anything but your still multiplying the numbers so if you were to graph it on a calculator it should pop up as a line but it’s not linear because there’s no addition in the function.

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
OA
12 inches
OB. 15 inches
OC 21 inches
OD. 40 inches

Answers

Answer:

Option B: 15 inches

Step-by-step explanation:

p=2w+2l so 12 (2*6) +2x= 42

42-12=30

30/2=15

The answer is:

15 inches

Explanation:

P = perimeter = 42

L = length = ?

W = width = 6

P rectangle = 2L + 2 W

Substitute into formula:

42 = 2L + 2 * 6

42 = 2L + 12

42 - 12 = 2L

30 = 2L

L = 30/2 = 15

L = 15 inches

Actual roots of f(x)=2x^2+2x-24

Answers

[tex]f(x) = 2 {x}^{2} + 2x - 24 [/tex]

[tex]f(x) = 2( {x}^{2} + x - 12) [/tex]

[tex]0 = 2( {x}^{2} + x - 12)[/tex]

Divided sides by 2

[tex] {x}^{2} + x - 12 = 0 [/tex]

[tex](x + 4)(x - 3) = 0[/tex]

_________________________________

[tex]x + 4 = 0[/tex]

[tex]x = - 4[/tex]

_________________________________

[tex]x - 3 = 0[/tex]

[tex]x = 3[/tex]

Answer:

x= 3, -4

Step-by-step explanation:

Set  2 x ² +  2 x  −  24  equal to  0 .

   2 x   ² +  2 x  −  24  =  0

Solve for  x .

Factor the left side of the equation.

2 ( x²   +  x  −  12 )  =  0

Factor  

x  ² +  x  − 12  using the AC method.

2 ( x  −  3 ) ( x  +  4 )  =  0

If any individual factor on the left side of the equation is equal to  0 , the entire expression will be equal to  0 .

x − 3 = 0

x + 4 = 0

Add  3  and subtract 4 to both sides of the equation.

x = 3

x = -4

Answer:

Blank 1: 2xy(4x-5)=3(4x-5)

Blank 2: (2xy+3)(4x-5)

Step-by-step explanation:

The first step in factoring this polynomial is to find the biggest common factor in both numbers inside the parenthesis, and the second step is to find the biggest common factor of the 2 addents.

The other steps are invalid, either because they don't respect positive or negative signs, or that they just factor it wrong completely.

Answer:  9/20 voted

========================================================

Explanation:

Let's say there are 100 students total. You can start with any number you want, but I'm picking a large round number to work with.

3/5 of the total voted, so (3/5)*100 = 0.6*100 = 60 people voted

Of the 60 who voted, 3/4 of those went to the winning candidate.

3/4 of 60 = (3/4)*60 = 0.75*60 = 45

We have 45 people who voted for the winning candidate out of 100 total students, so,

45/100 = (9*5)/(20*5) = 9/20

Meaning that 9/20 of the student body voted for the winning candidate.

--------------------------------

You could also multiply the two given fractions to get the same answer

(3/5)*(3/4) = (3*3)/(5*4) = 9/20

When multiplying, you multiply the numerators together and the denominators together. Reduce the fraction if possible.

Raleigh went to a gaming arcade for his birthday. His parent gave him $55 to spend. He purchased $14.25 in food and drinks, and put the rest of the money on the gaming arcade. Each Game in the arcade cost $1.25. Write a linear inequality to represent how many games g Raleigh can play in the arcade

Answers

Answer:

Step-by-step explanation:

Let [tex]g[/tex] denotes number of games that Raleigh can play in the arcade.

Cost of 1 game = $1.25

Cost of [tex]g[/tex] games = [tex]\$1.25g[/tex]

Amount spent in food and drinks = $14.25

Total amount spent by Raleigh = [tex]14.25+1.25g[/tex]

Also, amount with Raleigh = $55

So, the inequality is [tex]14.25+1.25g\leq 55[/tex]

Divide the inequality by 5

[tex]2.85+0.25g\leq 11[/tex][tex]2.85+0.25g\leq 11[/tex]

Solve for v.
- 13 = 7+5v

Answers

Answer:

Step-by-step explanation:

- 13 = 7+5v

subtract 7 on both sides to cancel out 7

- 20 = 5v

divide both sides by 5 to isolate v

- 4 = v, v is negative because negative divided by a positive will make your answer stay negative

   


ANSWER: V=4

EXPLANATION: First you would subtract 7 from both sides, then that should leave you with -20=5v divide five from both side you get the answer V=4.
