Answer:

$\frac{2}{25}$

Step-by-step explanation:

Given expression,

$\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }$

=> $\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }$

We see that $(x-2)$ is common in both numerator and denominator

hence canceling out we get:-

$\frac{2*18}{30*15}=\frac{2}{25}$

Answer= $\frac{2}{25}$

A box contains four equal sized cards labeled 1, 3,5, and 7. Tim will select one card from the bow. What is the probability that

Zielflug [23.3K]

Answer: The probability is zero.

Step-by-step explanation:

The labels on the 4 cards are 1, 3, 5 and 7. Because the cards are equal, the probability of dragging at random each one of them is equal to 1/4 = 0.25.

Now, the probability that Tim selects a card labeled with a 4 is equal to the number of cards labeled with a 4, divided the total number of cards.

We do not have cards labeled with a 4, so the probability is:

p = 0/4 = 0

because we do not have any card labeled with a 4, the probability of selecting one at random is equal to zero.

3x - 7 = 3x - 7

Add 7 on both sides

3x = 3x

Subtract 3x you get 0.
