Three times the second of three consecutive even integers is twelve less than twice the sum of the first and third integers.Find

Tresset [83]

Answer:

The largest even integer is <u>14</u>.

Step-by-step explanation:

Given:

Three times the second of three consecutive even integers is twelve less than twice the sum of the first and third integers.

Now, to find the largest even integers.

As, 2 is an even number.

Let an even integer be $2x.$

So, the three consecutive even integers are:

$2x,\ 2x+2,\ and\ 2x+4.$

Now, we have to add two to get next even number.

Thus, 3 times the second one of these is:

$3(2x + 2) \\= 6x + 6$

Now, the sum of the first and third ones are:

$2x + 2x + 4 \\= 4x + 4$

So, the twice the sum of the first and third integers is less than twelve:

$2(4x+4)-12\\=8x+8-12\\=8x-4$

Now, 3 times the second is 12 less than twice the sum of the other two:

$6x+6=8x-4$

<em>Getting the variables on one side and the number on other:</em>

$6+4=8x-6x$

$10=2x$

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

$5=x$

$x=5.$

Now, the even numbers we get are:

$2x=2\times 5=10\\2x+2=2\times 5+2=10+2=12\\2x+4=2\times 5+4=10+4=14.$

<em>Thus, the third number is the largest number which is 14.</em>

Therefore, the largest even integer is 14.

Of the $2400 Mr Calvin earned, he spent 3/8 on food, 1/3 on taxes and 1/6 on other expenses. Find out how much all this is in do

sattari [20]

Answer: $300

Step-by-step explanation:

Mr. Calvin earned $\$2400$

He spent $\frac{3}{8}$ on food i.e.

$\Rightarrow \dfrac{3}{8}\times 2400=\$900$

$\dfrac{1}{3}\quad \text{on taxes i.e.}\\\\\Rightarrow \dfrac{1}{3}\times 2400=\$800$

$\dfrac{1}{6}\ \text{on other expenses i.e.}\\\\\Rightarrow \dfrac{1}{6}\times 2400=\$400$

Remaining money = $2400-900-800-400=\$300$

So, he saved $300 after expenses
