Answer:

x = -6

Step-by-step explanation:

Simplifying

5x + 7 = 3x + -5

Reorder the terms:

7 + 5x = 3x + -5

Reorder the terms:

7 + 5x = -5 + 3x

Solving

7 + 5x = -5 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

7 + 5x + -3x = -5 + 3x + -3x

Combine like terms: 5x + -3x = 2x

7 + 2x = -5 + 3x + -3x

Combine like terms: 3x + -3x = 0

7 + 2x = -5 + 0

7 + 2x = -5

Add '-7' to each side of the equation.

7 + -7 + 2x = -5 + -7

Combine like terms: 7 + -7 = 0

0 + 2x = -5 + -7

2x = -5 + -7

Combine like terms: -5 + -7 = -12

2x = -12

Divide each side by '2'.

x = -6

Simplifying

x = -6

The solution to the equation 5x + 7 = 3x - 5 is x = -6.

We have,

To solve the equation 5x + 7 = 3x - 5, we need to isolate the variable x on one side of the equation.

Here's how we can do that:

Start by subtracting 3x from both sides of the equation to move all the x terms to one side:

5x + 7 - 3x = 3x - 5 - 3x

Simplifying, we get:

2x + 7 = -5

Next, subtract 7 from both sides of the equation to isolate the term with x:

2x + 7 - 7 = -5 - 7

Simplifying, we get:

2x = -12

Now, to solve for x, we divide both sides of the equation by 2:

(2x)/2 = (-12)/2

Simplifying, we get:

x = -6

Thus,

The solution to the equation 5x + 7 = 3x - 5 is x = -6.

Answer:

The rate of change or the slope is 7. (If you were to graph this, you would use 7/1.

Step-by-step explanation:

To find the slope when you're given two sets of points, you must find the distance from the y values and the distance from the x values!

Y values: distance from -2 to 5 is +7

X values: distance from -2 to -1 is +1

7/1 or just 7.

Hope this helps! :)

Answer:

The answer is 9.

Step-by-step explanation: Things to know: c is total cost and t tickets. 800 is the total cost so plug it in to c. You want to get t (tickets) alone.

original: c(t)=87.50t+12.50

Now with the 800: 800=87.50t+12.50

Subtract 12.50 to both sides: 787.5=87.50t

Divide 87.50 to both sides: 9=t

Answer:

It seems that the slope of this line is 1/5, yet none of the answers correspond to this. Double-check by finding two points on the line, and use the slope formula: (y2-y1/x2-x1). Also, remember that slope is rise/over run. I hope this can guide you!

Answer: the answer is not included in the options

Step-by-step explanation:

The slope of the line can be depicted by the following formulas: 1. Rise/run 2. Y1-y2/ x1-x2

If we were to use the second formula and “plug” in numbers for the variables, the slope we calculate is less than 1

Answer:

Side = [tex]5\sqrt5\ \text{feet}[/tex]

Step-by-step explanation:

Given that,

Area of a square room is 125 square feet

We need to find the length of one side of the room.

The area of a square shaped room is given by :

[tex]A=x^2[/tex]

Where, x is side of the square room

[tex]x=\sqrt{A} \\\\x=\sqrt{125}\\\\x=\sqrt{5\times 5\times 5}\\\\x=5\sqrt5\ \text{feet}[/tex]

So, the side of the room is [tex]5\sqrt5\ \text{feet}[/tex].

Respuesta: 50N

Explicación paso a paso:

Dado lo siguiente:.

Tensión (T) = 52,9 N

Masa (m) = 10,5 kg

La normal se obtiene usando la relación:

N = mg - T; donde N = normal, g = aceleración debida a la gravedad (9,8 m / s²)

N = mg - T

N = (10,5 * 9,8) - 52,9

N = 102,9 - 52,9

N = 50 N

Answer: 40

Step-by-step explanation: 50x0.8=40

Okay, maybe im wrong? But i dont see how its 4 thats more than half.

Rodger can do 46 pushups.

50 * 0.92 = 46

Edit: To better clarify, 0.92 is from 1.00 - 0.08.  

... 8 percent fewer than 100 percent is 92 percent; 1.00 - 0.08 = 0.92

Keep in mind that:

1.00 = 100%

0.08 = 8%

0.92 = 92%

After finding this you may multiply 50 * 0.92 to get 46.

Answer:

[tex]m=20c[/tex]

Step-by-step explanation:

Let m represent the total money collected and c represent the amount of cars washed.

We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:

[tex]m=kc[/tex]

Where k is a constant.

We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:

[tex]140=7k[/tex]

Find k. Divide both sides by 7:

[tex]k=20[/tex]

So, the value of k is 20.

We can now substitute k back into our direct variation equation:

[tex]m=20c[/tex]

This means that every car costs $20 to wash.

And we're done!
