Use the distributive property to write an expression that is equivalent to: 3(x + 5)

lana [24]

Answer:

3x=15

Step-by-step explanation:

Here's what I found on google about the distributive property-

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

3(x+5)

distribute the numbers- 3(x)+3(5)

solve- 3*5=15

3x+15

After two half-lives, what fraction of a radioactive sample has decayed?1/2 2/3 3/4 5/6

vitfil [10]

A half life means that half the sample decays.

If the sample size is 1 , then after one half life there would be x * 1/2 = 1/2 of the sample left.

For the 2nd half life, multiply 1/2 by 1/2 to get 1/4.

So after 2 half lives, there is 1/4 of the sample left, which means 3/4 of the sample decayed.

The answer is 3/4

Olenka [21]

Answer:

He have <u>47</u> ducks and <u>7</u> cows.

Step-by-step explanation:

Given:

Farmer Jones raises ducks and cows.

He looks out his window and sees 54 animals with a total of 122 feet.

Now, to find the each type of animal he have.

Let the number of ducks be $x.$

And the number of cows be $y.$

So, total number of animals are:

$x+y=54$

$x=54-y$ ....( 1 )

As, the feet of cows are 4 and ducks are 2.

Now, the total number of feet are:

$2(x)+4(y)=122$

$2x+4y=122$

Substituting the value of $x$ from equation (1) we get:

$2(54-y)+4y=122$

$108-2y+4y=122$

$108+2y=122$

<em>Subtracting both sides by 108 we get:</em>

$2y=14$

<em>Dividing both sides by 2 we get:</em>

$y=7.$

<em>The number of cows = 7.</em>

Now, to get the number of ducks we substitute the value of $y$ in equation (1):

$x=54-y\\x=54-7\\x=47.$

<em>The number of ducks = 47.</em>

Therefore, he have 47 ducks and 7 cows.
