When she adds 2 to both sides, the equation 4x = 3x results. Which solution will best illustrate what happens to x ?

kotykmax [81]

The solution will illustrate that the equation has one solution at x=0.

Given that adds 2 to both sides, the equation 4x = 3x results.

An algebraic equation may be described as a mathematical declaration wherein expressions are set the same as every other.

The equation is 4x=3x.

As given that add 2 on both sides, we get

4x+2=3x+2

Now, we will subtract 3x from both sides, we get

4x+2-3x=3x+2-3x

x+2=2

Further, we will subtract 2 from both sides, we get

x+2-2=2-2

x=0

Hence, When adds 2 to both sides, the equation 4x = 3x results that the equation has one solution x=0.

a roulette wheel has 38 slots numbered 1 to 36 and 0 to 00. the zeros are green. 18 of the slots are red and the rest are black.

Sever21 [200]

Answer:

$\dfrac{18}{38} \approx \bold{0.47}$

Step-by-step explanation:

Given that,

Total number of slots = 38

0 and 00 are green.

Remaining number of slots = 38 - 2 = 36

18 of the 36 slots are colored red.

Rest number of slots = 36 - 18 = 18, are colored black.

The wheel spins once.

To find:

Probability that the ball stops on red.

Solution:

Formula for probability of an event E is given as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Here, number of favorable cases is equal to the number of red slots.

Number of red slots = 18

Total number of cases = 38

$P(E) = \dfrac{18}{38} \approx \bold{0.47}$
