Answer:

Step-by-step explanation:

Multiply both sides by - 21

-21 x x/-21 + 15 = 13 x -21

x + 15 = - 273

x = - 273 - 15

x = - 288

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.

Can you please help me I don't understand
MA_775_DIABLO [31]
For #11 you add 54 + 59+ 57+ 54. Then you have 224. Then divide 224 by 4 since there are 4 numbers. Your answer should be 56 inches as the average, or mean.
Remember, when you divide, you divide by the number of all the numbers. I'm trying to make sense but hope this helps!
