How do you find the sum of three consecutive even numbers 42. what is the smallest of these numbers?

1 answer:

7 0

3 consecutive even numbers can be represented by 2n-2, 2n and 2n+2. Add these together to get 6n=42 so n=7 and the numbers are 12, 14, 16.

For every 9 black and white copies printed there are 2 color copies printed. If there are 200 color copies printed how many blac

Answer:

900 black and white copies are printed.

Step-by-step explanation:

Given:

For every 9 black and white copies printed there are 2 color copies printed.

If there are 200 color copies printed.

Now, to find the number of black and white copies are printed.

Let the number of black and white copies printed be $x.$

As given, for every 9 black and white copies printed there are 2 color copies printed.

So, 9 is equivalent to 2.

If there are 200 color copies printed.

Thus, $x$ is equivalent to 200.

Now, to solve by using cross multiplication method:

$\frac{9}{2} =\frac{x}{200}$

By cross multiplying we get:

$1800=2x$

Dividing both sides by 2 we get:

$900=x$

$x=900.$

Therefore, 900 black and white copies are printed.

HELP PLS:

Answer:

Bruce's function:

$\displaystyle y=\frac{1}{4}x$

Felicia's function:

$\displaystyle y=\frac{1}{9}x$

Bruce's tiles cover more area

Step-by-step explanation:

Functions

We need to compare the area covered by tile of both Bruce and Felicia. We are required to find the function y, the area covered by the number of tiles he used, x.

We know the tiles used by Bruce cover 1/4 of a square foot, this is written as:

$\displaystyle y=\frac{1}{4}x$

To find the function for Felicia, we must use the data provided in the table

For example,

For x=9 tiles, y=1 sq ft

For x=18 tiles, y=2 sq ft

If we set

$\displaystyle y=kx$

We can find the value of k

$\displaystyle 1=9k$

$\displaystyle k=\frac{1}{9}$

Thus

$\displaystyle y=\frac{1}{9}x$

Testing the constructed function with x=18 and x=27

$\displaystyle y=\frac{1}{9}18=2$

$\displaystyle y=\frac{1}{9}27=3$

The function is complete and accurate.

Comparing both functions we see that Bruce's tiles cover more area because

$\displaystyle \frac{1}{4}>\frac{1}{9}$
