Simplify the expression and show work 4(3x-2)-7(x+5)

Gennadij [26K]

Answer:

5x - 43

Explanation:

Given the below expression;

$4\left(3x-2\right)-7\left(x+5\right)$

To simplify the above, we'll go ahead and use the numbers outside the parentheses to multiply the ones inside to clear the parentheses as seen below;

$\begin{gathered} 12x-8-7x-35 \\ =12x-7x-8-35 \\ =5x-43 \end{gathered}$

So the answer is 5x - 43

Assume that you randomly select 6 cards from a deck of 52. what is the probability that all of the cards selected are hearts?

Ira Lisetskai [31]

There are 13 hearts in a 52 deck.

You can think about it like this:

P = (13/52)*(12/51)*(11/50)*(10/49)*(9/48)*(8/47) = 0.00008428903476

9.35 as a fraction in simpliest form

Lana71 [14]

We know that
the number $9.35$
is equal to
$9+0.35$
and
$0.35$ is equal to
$35/100$
divide by 5 both members
$\frac{35}{100} = \frac{7}{20}$

therefore

the number $9.35$ is equal to $9 \frac{7}{20}$

What is the distance between the points? Round to the nearest tenth if necessary.

Svetlanka [38]

Answer:

1.7

Step-by-step explanation:

You do rise over run or y/x to find your answer. You go over 6 and up 10 to get from the lower point to the one on top. 10/6=1.666667 and rounded will be 1.7
