The sum of three consecutive even numbers is 306. Find the three numbers.​
zysi [14]

Answer:

100, 102, 104

Step-by-step explanation:

Hi there!

Let <em>x</em> be equal to the first number in the set of the three consecutive even numbers.

We're given that the sum of three consecutive even numbers is 306.

Because <em>x</em> is the first number, the next would be <em>x</em>+2, and then <em>x</em>+4. These are our even numbers.

We can now set up an equation:

(x)+(x+2)+(x+4)=306

Combine like terms:

x+x+x+2+4=306\\3x+6=306\\3x=300\\x=100

Therefore, the first number in the set of 3 numbers is 100.

The next two even numbers after 100 is 102 and 104.

Therefore, the three numbers are 100, 102 and 104.

I hope this helps!

Luci cuts a board that is 5/7 yard long into pieces that are 5/14 yard long. How many pieces does she cut?
zvonat [6]

Answer:

So total number of pieces will be 2

Step-by-step explanation:

We have given the total length of the board =\frac{5}{7}yard

It is given that Luci cuts the board into pieces of =\frac{5}{14}yard long

We length of each piece = =\frac{5}{14}yard

We have to find the total number of pieces

For finding total number of pieces we have to divide the total length of board by length of each piece

So number of pieces =\frac{\frac{5}{7}}{\frac{5}{14}} = 2
