The sum of two consecutive even integers is 186. What are the two numbers?
ozzi

Answer: 92 and 94

Step-by-step explanation:

x = first number

x + 2 = second number

x + x + 2 = 186

simplify

2x + 2 = 186

subtract 2 from both sides

2x = 184

divide both sides by 2

x = 92

92 + 2 = 94

The numbers are 92 and 94.

Type a digit that makes this statement true.
Archy [21]

Answer:

So information at the bottom:

since every number in a thousand spot needs to have 3 digest, we need to add a zero onto 29,422,33<u>0</u>. If we didn’t add a zero, then the problem wouldn’t make much since. So if we divide 29,422,330 by 2, our answer would be 14,711,165. A whole bunch of numbers, but nothing that can’t be solved!

<h3>Hope this helps!✌️</h3>
