There are three consecutive even integers. If twice the first integer added to the second is 268,244, find all three integers.
r-ruslan [8.4K]

Answer:

89414,89416,89418

Step-by-step explanation:

Let n bet the positive integer and then 2n is an even integer because multiplying n with 2 makes it an even integer.

Now, 2n+2, 2n+4 are the next integers.

Therefore, three consecutive integers are: 2n, 2n+2, 2n+4.

It is given that twice the first integer added to the second is 268,244 that means:

2(2n)+(2n+2)=268244

4n+2n+2=268244

6n=268242

n=44707

Therefore, three consecutive integers are:

2n=89414, 2n+2=89416, 2n+4=89418

cestrela7 [59]

Answer:

Step-by-step explanation:

7 friends have a similar cell phone plans. The price of each plan is $x. This means that the basic cost of all the plans is $x. The total basic cost for the 7 plans would be

7 × x = $7x

3 of 7 friends pay an extra $4 per month for unlimited text messaging. The total amount paid by the 3 friends would be

3 × 4 = $12

Therefore, the total cost for the 7 plans would be

7x + 12

What value of x is in the solution set of 4x – 12 5 16 + 8x?
TEA [102]

Answer:

4x-12= 16 +8x

And we can subtract 4x in both sides and we got:

-12 = 16 +4x

Now we can subtract in both sides 16 and we got:

-28 = 4x

And if we divide both sides by 4 we got:

x = -7

And the best solution would be:

-7

Step-by-step explanation:

For this case we assume the following equation:

4x-12= 16 +8x

And we can subtract 4x in both sides and we got:

-12 = 16 +4x

Now we can subtract in both sides 16 and we got:

-28 = 4x

And if we divide both sides by 4 we got:

x = -7

And the best solution would be:

-7
