Mike thought of a number. He added to it to two other numbers. One of these numbers was 12 less than his number, the other was 1
2 more than his number. The result of the addition was 15. What was Mike’s original number?
If Mikes original number is x, the equation is?
The number is?
1 answer:
Answer:
number 1 + number 2 + number 3 = 15
Number 1 = x + 12
Number 2 = x - 12
Number 3 = x
(x + 12) + (x - 12) + x = 15
x + 12 + x - 12 + x = 15
x + x + x +12 -12 = 15
3x = 15
x = 15/3 = 5
Check:
Number 1 = 17
Number 2 = 5 -12 = -7
Number = 5
number 1 + number 2 + number 3 = 15
17 + (-7) + 5 = 15
10 + 5 = 15
15 = 15

Where is the question dude?
The answer is 3h.
Because 3h is like 3 x H
To solve this, you'll need the interest formula: <span> P(1 + rt).
Then, plug in the numbers:
$500(1.08*3) = $1,620. That's your answer.</span>
