Can someone put this in order for me? Because I'm so confused.

Answers

Answer:

Step-by-step explanation:

[tex]24a-3(2a-5)=51[/tex]

Step 1: Let's solve first so we can order  it later.

[tex]24a-6a+15=51\\18a+15=51\\-15 -15\\\18a=36\\\\[/tex]

Divide 18 both sides.

[tex]a=2[/tex]

Ok so we have everything solved answer: a=2.

Now we need to order.

Step 1. Distribute 3.

Step 2. Combine like terms 24a and 6a.

Step 3. Subtract 15 from both sides.

Step 4. Divide both sides by 18.

Hope this helps :)

The girls played 20 games.

Step-by-step explanation:

15% ÷ 3 = 5

100% ÷ 5 = 20 games

Who can help me with this ?

Answers

Answer:

I believe the measure of the sum of interior angles of  square is 360 degrees, and we know that all the angles are equal to 3x. You'd set up the equation to look like 3x+3x+3x+3x=360

simplify that, and you get 12x=360

this means x= 30

Literal Equations: Solve for p:
5(4x + p)=w

Answers

Answer:

Step-by-step explanation:

Simplifying

5(4x + p) = w

Reorder the terms:

5(p + 4x) = w

(p * 5 + 4x * 5) = w

(5p + 20x) = w

Solving

5p + 20x = w

Solving for variable 'p'.

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

Add '-20x' to each side of the equation.

5p + 20x + -20x = w + -20x

Combine like terms: 20x + -20x = 0

5p + 0 = w + -20x

5p = w + -20x

Divide each side by '5'.

p = 0.2w + -4x

Simplifying

p = 0.2w + -4x

How to solve 2(x+13)=9

Answers

Answer:

x = -17/2

Step-by-step explanation:

2(x+13)=9

2x+26=9 (multiplying 2 with both the numbers)

2x=9-26 (shifting 26 on the other side of the equation changes its sign)

2x=-17

x=-17/2 (2 is in multiplication form, so shifting on the other size changes it into division)

Answer:

2 x x + 2x13=8

or,2x+26=9

or,2x=9-26

or,2x= -17

or,x= -17/2

so, x= -8.5

Answer:  B) -4

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

Explanation:

Point Q is located at (0,w). We see that x = 0 and y = w.

So we'll replace x with 0 and y with w. Then we solve for w.

2x+3y = -12

2(0)+3(w) = -12

0+3w = -12

3w = -12

3w/3 = -12/3

w = -4

In the second to last step, I divided both sides by 3 to undo the multiplication of 3. Saying 3w means "3 times w".

Side note: The point Q is the y intercept as this is the location where the diagonal line 2x+3y=-12 crosses the vertical y axis.

Which linear inequality is represented by the graph?
