Step-by-step explanation:

Let's solve your equation step-by-step.

5(−3x−2)−(x−3)=−4(4x+5)+13

Step 1: Simplify both sides of the equation.

5(−3x−2)−(x−3)=−4(4x+5)+13

5(−3x−2)+−1(x−3)=−4(4x+5)+13(Distribute the Negative Sign)

5(−3x−2)+−1x+(−1)(−3)=−4(4x+5)+13

5(−3x−2)+−x+3=−4(4x+5)+13

(5)(−3x)+(5)(−2)+−x+3=(−4)(4x)+(−4)(5)+13(Distribute)

−15x+−10+−x+3=−16x+−20+13

(−15x+−x)+(−10+3)=(−16x)+(−20+13)(Combine Like Terms)

−16x+−7=−16x+−7

−16x−7=−16x−7

Step 2: Add 16x to both sides.

−16x−7+16x=−16x−7+16x

−7=−7

Step 3: Add 7 to both sides.

−7+7=−7+7

Since you did not want the answer the things you need to solve this question are below.

Step-by-step explanation:

In order to solve this, you will need to read about the scale factor. Here is a picture telling about it briefly.

Answer: Its C

Step-by-step explanation:

24   +   25   +   26   +   27   +   28   +   29   +   30   +   31   +   32   +   33   +   34   ÷   11 = 29

Answer:

c

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

Set 1

sum = (2 × 27) + (2 × 28) + (3 × 29) + (2 × 30) + (1 × 33)

       = 54 + 56 + 87 + 60 + 33 = 290

The count is 10 ( number of dots ), then

mean = [tex]\frac{290}{10}[/tex] = 29

Set 2

sum = (4 × 24) + (4 × 25) + (2 × 27)

       = 96 + 100 + 54 = 250

The count is 10 ( number of dots ), then

mean = [tex]\frac{250}{10}[/tex] = 25

4) [tex]25 {y}^{2} - 16[/tex]

[tex] = > {(5y)}^{2} - {4}^{2} [/tex]

[tex] = > (5y + 4)(5y - 4)[/tex]

5) [tex]9 {x}^{2} - 30x + 25[/tex]

[tex] = > {(3x)}^{2} - 2 \times 3x \times 5 + {(5)}^{2} [/tex]

[tex] = > {(3x - 5)}^{2} [/tex]

[tex] = > (3x - 5)(3x - 5)[/tex]

6) [tex] {p}^{2} + 2p - 15[/tex]

[tex] = > {p}^{2} + 5p - 3p - 15[/tex]

[tex] = > p(p + 5) - 3(p + 5)[/tex]

[tex] = > (p + 5)(p - 3)[/tex]

7) [tex] {y}^{2} + 8y + 12 = 0[/tex]

[tex] = > {y}^{2} + 2y + 6y + 12[/tex]

[tex] = > y(y + 2) + 6(y + 2)[/tex]

[tex] = > (y + 2)(y + 6)[/tex]

Step-by-step explanation:

The slope of Abha's climb is given by the equation

Slope m = 2

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be A

Now , let the point be P ( x , y )

And , the equation is given by

The horizontal distance covered by Abha x = 20 yards

The vertical distance covered by Abha y = 40 yards

Now , the slope of the point is given by the equation

Slope m = vertical distance covered by Abha  / horizontal distance covered by Abha

Substituting the values in the equation , we get

Slope m of Abha's climb = y/x

Slope m of Abha's climb = 40 / 20

Slope m of Abha's climb = 2

Therefore , the slope of the line is m = 2

Hence , The slope of Abha's climb is given by the equation Slope m = 2

Answer:

x = 3 and y = 1

Step-by-step explanation:

Give system of equations are :

8x-9y=15 ...(1)

−x+4y=1 ...(2)

Multiply equation (2) by 8.

−8x+32y=8 ..(3)

Add equation (1) and (3).

8x-9y -8x + 32y = 15+8

23y = 23

y = 1

Put the value of y in equation (2).

−x+4(1)=1

-x = -4+1

x = 3

Hence, the values of x and y are 3 and 1.

Answer:

Step-by-step explanation:

x=(115cos50+160cos130)=-28.9254

y=(115sin50+160sin130)=210.6622

m^2=x^2+y^2

m=212.64

angle=180+arctan(y/x)

angle=97.82

v=212.64 at 97.82 degrees

Answer:

x=29

Step-by-step explanation:

We know for a fact that in a square:

- All of its angles have equal measure (90 degrees)

(e.g. Measure of Angle CAT, measure of Angle CST = 90 degrees)

Now that we know the facts, let's try to find x.

Now since we know that all the angles are equivalent to 90 degrees, we can say that Measurement of Angle SCA is 90 degrees. So:

[tex]90=3x+3[/tex]

Next, we'll simply just isolate the x:

[tex]90=3x+3\\90-3=3x+3-3\\87=3x\\\frac{87=3x}{3} \\29 = x[/tex]

Answer:

x = -6

Step-by-step explanation:

13x = 3(x - 20)              {Use distributive method:a(b+c)=(a*b) + (a*c)

13x = 3*x - 3*20

13x = 3x - 60            {Subtract '3x' from both sides}

13x -3x = -60      

    10x = -60      {Divide both sides by 10}

        x= -60/10

       x = -6

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

Explanation:

To isolate s, we need to undo the division. We'll multiply both sides by 3

14 = s/3

3*14 = 3*(s/3)

42 = s

s = 42

-------

As a check,

14 = s/3

14 = 42/3 .... replace s with 42

14 = 14

We get the same thing on both sides, so this confirms we have the correct value of s.
