Answer:
15x*45 i think
Step-by-step explanation:
n - the first number
n + 11 - the second number
2n + 6 - the third number
81 - the sum of three numbers
The equation:
n + (n + 11) + (2n + 6) = 81
n + n + 11 + 2n + 6 = 81 <em>combine like terms</em>
(n + n + 2n) + (11 + 6) = 81
4n + 17 = 81 <em>subtract 17 from both sides</em>
4n = 64 <em>divide both sides by 4</em>
n = 16
the largest of the tree numbers is the third number 2n + 6.
Substitute the value of n:
2(16) + 6 = 32 + 6 = 38
<h3>Answer: 38</h3>
Answer: X = 4
Step-by-step explanation:
the whole line is 18 long
10 + 12 = 22
22 - 18 = 4
10 - 4 = 6
12 - 4 = 8
8 + 6 = 14
14 + 4 = 18
