Step 1: Simplify both sides of the equation.

5x−15−(2x+5)=3x−20

5x−15+−1(2x+5)=3x−20(Distribute the Negative Sign)

5x+−15+−1(2x)+(−1)(5)=3x−20

5x+−15+−2x+−5=3x−20

5x+−15+−2x+−5=3x+−20

(5x+−2x)+(−15+−5)=3x−20(Combine Like Terms)

3x+−20=3x−20

3x−20=3x−20

Step 2: Subtract 3x from both sides.

3x−20−3x=3x−20−3x

−20=−20

Step 3: Add 20 to both sides.

−20+20=−20+20

0=0

(2,1)

The answer is (2,1)

Step-by-step explanation:

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x - 15 = 15

+15 +15

15x = 30

/15 /15

x = 2

Answer:

Step-by-step explanation:

Make this an expression

12,400x1 1/5

Now, Solve this expression

-make 1 1/5 an improper fraction

12,400x 6/5

-multiply the numerators by the numerators and the denominators by the denominators... remember that a whole number's decimal is always 1

12,400/1 x 6/5

12,400x6= 74400

1x5=5

74400/5= 14880

Is 14880 less than or greater than 12400? It is greater.

The probability of him getting one red marble from 5 red marbles in one bag and one blue marble from 4 blue marbles in the other bag is 4/11.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of marbles in first bag = 11

Yellow marbles = 6

Red marbles = 5

Number of marbles in the second bag = 6

Green marbles = 2

Blue marbles = 4

The probability of him getting one red and one blue marble.

= [tex]\frac{^5C_1}{^{11}C_1} \times\frac{^4C_1}{6^C_1}[/tex]

= 5/11 x 4/5

= 4/11

Thus,

The probability of him getting one red and one blue marble is 4/11.

31.625

Step-by-step explanation:

Multiply height by width so

5.5(5.75) = 31.625

The area of the CD case will be [tex]31.625[/tex] squared inch .

Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

Area [tex]= Length * Breadth[/tex]

We have,

A rectangle.

Length of rectangle [tex]=5.5"[/tex]

Breadth of rectangle [tex]=5.75"[/tex]

So,

The area of rectangle [tex]= Length * Breadth[/tex]

                                    [tex]=5.5*5.75[/tex]

                                    [tex]= 31.625[/tex] squared inch

So, the area of CD case is [tex]31.625[/tex] squared inch.

Hence, we can say that the area of the CD case will be [tex]31.625[/tex] squared inch .

Answer:

Step-by-step explanation:

Some of the expressions that can be derived that have the values of 12 are:

i. 2a = 2 x 6

      = 12

ii. 3b = 3 x 4

        = 12

iii. (b  + c) x a = (4 - 2) x 6

                = 2 x 6

                = 12

iv. 2b + [tex]c^{2}[/tex] = (2 x 4) + (-2 x -2)

                = 8 + 4

                = 12

v. [tex]b^{2}[/tex] -  [tex]c^{2}[/tex] = (4 x 4) - (-2 x -2)

             = 16 - 4

             = 12

vi. [tex]c^{4}[/tex] - b = (-2 x -2 x -2 x -2) + 4

             = 16 - 4

             = 12

Step-by-step explanation:

You can insert different values of x to find y

For example:

x = 4

Plug in x into the equation

y = -1/2(4) + 5

y = -2 + 5

y = 3

So your point will be (4, 3)

If you do 1 more like this, you can draw a line between them. Or you can use Desmos to graph the line.
