Answer:

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

<=>5*(5x-2) = 7*(3x+2) (x is not equal to -3/2 or 2/5)

<=> 25x -10 = 21x +14   (x is not equal to -3/2 or 2/5)

<=> 4x = 24                   (x is not equal to -3/2 or 2/5)

<=> x = 6 (valid)

A Car is traveling westward with a constant velocity of 20 m/s, what is the net force acting on the car?
gtnhenbr [62]

According to Newton's second law of motion, the force acting on an object is equal to the mass multiplied by the acceleration of the moving object. Since the object is moving in a constant velocity, acceleration is zero. Hence regardless of the mass of the car, the force acting is zero provided that air resistance and friction is negligible

<h3>What is the probability?</h3>

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

The number of yellow shirts = 1

The probability that his outfit will be the black pants with the yellow shirt

= 2/12

Solve for r <br> 12r=36 pro
blsea [12.9K]

Answer:

r = 3.

Step-by-step explanation:

The equation means 12 x r = 36. Well to work this out we can do a reverse method using division. We're going to do 36 divided by 12. The answer to that is 3 so r = 3. Let's check it now! 12 x 3 = 36? That sounds correct to me so there's our answer.

Hope that helps. x
