-7x-14=2x+13 What does x equal?

Answers

Answer: x = -3

Step-by-step explanation:

Given

-7x - 14 = 2x + 13

Subtract 2x on both sides

-7x - 14 - 2x = 2x + 13 - 2x

-9x - 14 = 13

Add 14 on both sides

-9x - 14 + 14 = 13 + 14

-9x = 27

Divide -9 on both sides

-9x / -9 = 27 / -9

[tex]\boxed {x = -3}[/tex]

Check:

Left-hand side = -7x - 14

                        = -7 (-3) - 14

                        = 21 - 14

                        = 7

Right-hand side = 2x + 13

                           = 2 (-3) + 13

                           = -6 + 13

                           = 7

7 = 7

Hope this helps!! :)

4 – 2(x + 7) = 3(x + 5)

Answers

Answer:

x = -5

Step-by-step explanation:

4 – 2(x + 7) = 3(x + 5)

Distribute

4 - 2x-14 = 3x+15

Combine like terms

-2x-10 = 3x+15

Add 2x to each side

-2x-10 +2x= 3x+15+2x

-10 = 5x+15

Subtract 15 from each side

-10-15 = 5x+15-15

-25 = 5x

Divide by 5

-25/5 = 5x/5

-5 =x

Answer:

x = -5

Step-by-step explanation:

4 - 2(x + 7) = 3(x + 5)

so, let's do the multiplications. remember, when two terms are multiplied, then everything of the left is multiplied with everything on the right. and a "-" flips signs.

2(x + 7) = 2x + 14

3(x + 5) = 3x + 15

so, in total

4 - 2x - 14 = 3x + 15

now, we add combinable things together, and we can also move things from one side of the equation to the other (by adding our subtracting the same thing on both sides, so that the value of the expression remains unchanged).

-2x - 10 = 3x + 15

-25 = 5x

and now, what applied to adding and subtracting also aims to multiplication and division. again, it is important to do the same thing to both sides.

-5 = x

draw the graph of the following equation 2(x+1)=3(y-1)-4
anyone knows how to do this ?

Answers

9514 1404 393

Answer:

   see attached

Step-by-step explanation:

I find the easiest way to draw a graph is to let a graphing calculator do it. That result is shown in the attachment.

__

If you're drawing this by hand, it can be easier if it is simplified a bit.

  2(x +1) = 3(y -1) -4

  2x +2 = 3y -3 -4 . . . . . . eliminate parentheses

  2x +9 = 3y . . . . . . . . . . add 7

  y = 2/3x +3 . . . . . . . . . divide by 3

This is the equation of the line in slope-intercept form. It tells you that the point (0, 3) on the y-axis is on the line, and that it has a slope of 2/3. That means it has a rise/run of 2/3, or a rise of 2 units for each 3 units to the right.

Starting from point (0, 3), another point on the line will be 3 over and 2 up, at (3, 5). Once you have a couple of points plotted, you can draw the line through them to make your graph.

What is m O M ZABC = 60°
OM ABC = 67°
OM ZABC = 120°
O M ABC = 127°

Answers

Answer:

∠ ABC = 127°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ABC is an exterior angle of the triangle , then

∠ ABC = ∠ BDC + ∠BCD = 60° + 67° = 127°

We know that we have a triangle and we want to find the value of its angle which will be given by  53°.

We know that the sum of all the interior angles of a triangle must equal 180 degrees, so we find then:

[tex]ABC=180[/tex]

Now making the sum of the angles already known and equating to 180, we find that:

[tex]180=67+60+x\\x=180-127\\x= 53[/tex]

If there are 3.28 feet in a meter , how many are in the 110 meter dash?

Answers

Answer:

360.8

Explanation:
3.28*110

In 110 meter dash, there are 360.8 feet.

What is Simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given that, there are 3.28 feet in a meter

Since,

in 1 meter there are = 3.28 feet

Thus in 110 meters there are = 3.28 * 110 feet

In 110 meters, there are = 360.8 feet

Therefore, there are 360.8 feet in 110 meters dash.
