ANSWER

A. Noah is correct because the two sides of the equation are equivalent expressions.

EXPLANATION

The equation given to Noah was

-3(x + 4) + 2x = 2(x - 6) - 3x

He expanded to get:

-3x - 12 + 2x = 2x - 12 - 3x

He then further simplified each side of the equation to get;

-x - 12 = -x - 12

Both sides of this equation are equivalent.

Therefore the equation has infinitely many solutions.

The correct answer is A

Answer:

Option A) Noah is correct because the two sides of the equation are equivalent expressions.

Step-by-step explanation:

We are given the following information in the question:

-3(x + 4) + 2x = 2(x - 6) - 3x\\-3x - 12 + 2x = 2x - 12 - 3x\\-x - 12 = -x - 12

The above equation has infinitely many solutions.

Infinite solution:

If an equation end up with equal values on each side of the equation, then there are infinite solution as for all the values of x the equations would be satisfied.

Noah is correct.

Option A) Noah is correct because the two sides of the equation are equivalent expressions.

The formula for velocity of an object is the equals d over t where he is a velocity of the object t is the distance traveled and
butalik [34]

Answer:

(a)\ t =\frac{d}{v}

(b)\ d = vt

Step-by-step explanation:

<em>The question is mixed up with details of another question. See comment for original question</em>

<em />

<u>Given</u>

v = \frac{d}{t}

v \to velocity

d \to distance

t \to time

Solving (a): Solve for time

We have:

v = \frac{d}{t}

Cross multiply

t * v = d

Make t the subject

t =\frac{d}{v}

Solving (b): Solve for distance

We have:

v = \frac{d}{t}

Cross multiply

d = v * t

d = vt
