Answer:
x=0

Explanation:

Cancel 2 on both sides leaving you with

x+5x−4x=0

Then Simplify x+5x−4x to 2x.

2x=0

Divide both sides by 2

The difference between a number and five equals three. Translate this sentence to an equation and then find the

laila [671]

Answer:

the equation will be:

$\mathbf{x-5=3}$

solving the equation we get x=8

Option B is correct.

Step-by-step explanation:

We need to write equation for this sentence:

The difference between a number and five equals three.

Let number = x

So, the equation will be:

$\mathbf{x-5=3}$

Now, solving the equation to find value of x

$x-5=3$

Adding 5 on both sides

$x-5+5=3+5\\x=8$

So, solving the equation we get x=8

Option B is correct.

2 cars are 700 miles apart. They travel toward each other. One of the cars travels at 75mph, the other travels at 100 mph. How l

olga2289 [7]

Answer: C 4

Step-by-step explanation:

Use the formula: distance = rate x time

We can say that train 1 travels a distance of x, and train 2 travels a distance of 700 - x

The rate of train 1 is 75 mph, and the rate of train 2 is 100 mph

The time traveled for the two trains will be the same. We can represent that with the variable t.

We have the following equation for train 1:

x = 75t

For train 2, we have this equation:

700 - x = 100t

Use the Substitution Method by replacing x in the equation for train 2 with the value 75t.

700 - 75t = 100t

700 = 175t

700/175 = 4 hours.

It will take 4 hours for the two trains to meet.

What are the solution(s) to the quadratic equation 50 – x2 = 0?

Dmitrij [34]

Answer:

x = ± $5\sqrt{2}$

Step-by-step explanation:

We have been given the quadratic equation;

$50-x^{2}=0$

The first step is to subtract 50 from both sides of the equation;

$50-x^{2}-50=0-50$

$-x^{2}=-50$

Multiplying both sides by -1 yields;

$x^{2}=50$

The final step is to obtain square roots on both sides;

$\sqrt{x^{2} }=\sqrt{50}\\x=+/-\sqrt{50}$

Therefore, x = ± $5\sqrt{2}$
