There are three consecutive even integers. If twice the first integer added to the second is 268, 244 find all three integers.

Rudik [331]

Answer:

The numbers would be 89,414 , 89,416, and 89,418

Step-by-step explanation:

In order to find this, start by setting the lowest number as x. Then we can determine that the next two even integers are x + 2 and x + 4. From this we can write the following equation.

2(x) + x + 2 = 268,244

3x + 2 = 268,244

3x = 268,242

x = 89,414

Since the first number is 89,414, we know the next two are 89,416 and 89,418.

A sailboat's Saul has three sides that are all the same length. Each side measures x - 10 units. The sail's perimeter is 63 unit

ruslelena [56]

Answer:

The value of 'x' is 31 unit

Step-by-step explanation:

Given:

Measure of each side = $x-10\ units$

Perimeter of sails = 63 units.

We need to find the value of x.

Solution:

Now we can see that from given data.

A sailboat's Saul has three sides.

Now assuming it to be triangle we get;

"Perimeter of triangle is equal to sum of all side."

So we can say that;

$x-10+x-10+x-10 =63\\\\3x-30=63$

Now adding both side by 30 we get;

$3x-30+30=63+30\\\\3x=93$

Now dividing both side by 3 we get;

$\frac{3x}{3}=\frac{93}{3}\\\\x=31 \ units$

Hence the value of 'x' is 31 units.
