Answer:

x = -(8 - 3 y)/y

Step-by-step explanation:

Solve for x:

y = 8/(3 - x)

y = 8/(3 - x) is equivalent to 8/(3 - x) = y:

8/(3 - x) = y

Take the reciprocal of both sides:

(3 - x)/8 = 1/y

Multiply both sides by 8:

3 - x = 8/y

Subtract 3 from both sides:

-x = (8 - 3 y)/y

Multiply both sides by -1:

Answer: x = -(8 - 3 y)/y

$\huge\boxed{x=3-\frac{8}{y}}$

$y=\frac{8}{3-x}$

Multiply both sides of the equation by $(3-x)$ . $y(3-x)=8$

Divide both sides by $y$ . $3-x=\frac{8}{y}$

Subtract $3$ from both sides. $-x=\frac{8}{y}-3$

Multiply both sides by $-1$ , making everything opposite. $\boxed{x=3-\frac{8}{y}}$

Paul baked 56 blueberry muffins. His brother Pete ate 7 muffins and his father William ate 5 muffins. Which expression can Paul

Natasha_Volkova [10]

Answer: 56-(7+5)

Step-by-step explanation:

You can find the amount of muffins left over by adding up the amount of muffins that were eaten and subtracting them from the original amount of blueberry muffins, so the answer is 56-(7+5).

(7+5 is in parentheses because if not, you would have 56-7+5 and get 54).

what is the difference between the mean and the median of the following distribution? {1,1,1,2,2,2,2,3,3,4,4,4,4,5,5,6,7,7,8,8,9

iren2701 [21]

The given distribution =

1, 1, 1, 2, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7, 7, 8, 8, 9

To find mean, we have to add the given numbers and divide it by the total number of terms given.

Here 21 total numbers given.

Mean = (1+1+1+2+2+2+2+3+3+4+4+4+4+5+5+6+7+7+8+8+9) /21

= (88)/21 = 4.19 (Approximate upto two decimal place)

Median is the middle value of the distribution.

1, 1, 1, 2, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7, 7, 8, 8, 9

There are 21 numbers given. So middle value is the number in the 11th position.

The number in the 11th position is 4.

So, the median of the distribution = 4

We have to find the difference between mean and median here. To find the difference we have to subtract mean and median.

Therefore, the required difference = 4.19 - 4 = 0.19

0.19 is the required answer here.

So, option b is correct.

Step-by-step explanation:

If he is running 1 mile in 10 minutes and he needs to run 9 miles the just multiply 9 by 10 to get 90 then simplify if you need to to get 1 hour and 30 minutes.

A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of

cestrela7 [59]

The amount of gas consumed by first and second car were 20 gallons and 15 gallons respectively.

Explanation

Suppose, $x$ gallons of gas were consumed by the first car.

As the total gas consumption in one week is 35 gallons, so the amount of gas consumed by second car will be: $(35-x)$ gallons.

The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas.

So, the distance traveled by the first car in $x$ gallons of gas $=35x$ miles and the distance traveled by the second car in $(35-x)$ gallons of gas $=15(35-x)$ miles.

Given that, the two cars went a combined total of 925 miles. So, the equation will be.....

$35x+15(35-x)=925\\ \\ 35x+525-15x=925\\ \\ 20x=925-525=400\\ \\ x=\frac{400}{20}=20$

So, the amount of gas consumed by the first car is 20 gallons and the amount of gas consumed by the second car is: (35 - 20) = 15 gallons.
