Answer:
-2
Step-by-step explanation:
We usually start measuring the height from the ground, so basically the positive direction is above the ground, for example 2 is the best number which represents 2m above the ground.
So the negative sign represents the depth below the ground.
Subtract Harmony Trail from Mountain Trail so 844-528=316
Answer:
see explanation
Step-by-step explanation:
1
x - 4 = 20 ( multiply through by 3 to clear the fraction )
2x - 12 = 60 ( add 12 to both sides )
2x = 72 ( divide both sides by 2 )
x = 36
2
4 = 
( multiply both sides by 2 to clear the fraction )
8 = - 1 + x ( add 1 to both sides )
9 = x
3
12(x + 9) = - 108 ( divide both sides by 12 )
x + 9 = - 9 ( subtract 9 from both sides )
x = - 18
4
5x + 14 = - 7 ( subtract 14 from both sides )
5x = - 21 ( divide both sides by 5 )
x = - 
= - 4.2
Answer:
for A it's the first answer and for b 15826
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
