What is the solution to the equation? x = 1 x = 6 x = 12 x = 24

Answer:

<h2>X=6</h2>

Option B is the correct option

solution,

\sqrt{5x - 7}  =  \sqrt{3x + 5}

Cancel the square roots on both sides

5x - 7 = 3x + 5

Add 7 to both sides

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

Simplify

5x = 3x + 12

Subtract 3x from both sides

5x - 3x = 3x + 12 - 3x

Simplify

2x = 12

Divide both sides by 2

\frac{2x}{2}  =  \frac{12}{2}

Simplify

x = 6

Hope this helps...

Good luck on your assignment..

Nikita's distance from her for the second part of the race was 1.5 kilometers.

Since Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand, and in the first part of the race, her average speed was 8.75 kilometers per hour, while for the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour, to determine which expression represents Nikita's distance for the second part of the race the following calculation must be performed:

  • 8.75 x 0.65 + 6 x 0 = 5.68
  • 8.75 x 0.50 + 6 x 0.15 = 5.275
  • 8.75 x 0.40 + 6 x 0.25 = 5
  • 100 = 60
  • 40 = X
  • 40 x 60/100 = X
  • 24 = X
  • 39 - 24 = 15
  • 15 = 1/4 hour
  • 6/4 = 1.5

Therefore, Nikita's distance from her for the second part of the race was 1.5 kilometers.

Which order pair is a solution of this equation. 5x+y=-25
crimeas [40]

Answer:

(-5,0) or (0,-25) is another solution

Step-by-step explanation:

Do you have a list of choices? If not, you could choose random choices for x and y to determine if they are solutions. Start by letting y = 0. We see that x = -5, so (-5, 0) is a solution to this equation. In fact, it represents the x-intercept of this line. Now, let x = 0. We now see that y = -25, so (0, -25) is another solution to the equation of this line. This coordinate pair is the y-intercept of the line. Try using other values of x and y to see if you can come up with other solutions to this equation.
