Answer:
<h3>
f(4) = 14</h3>
Step-by-step explanation:
f(n) = n + 10
f(4) = 4 + 10 = 14
<span>The answer to this question is Step 7.
Step 7 ⇒ −8 + 10 = x
− 10 + 10
This is where 10 is being added to both sides. It is not Step 4 as that uses the Subtraction Property of Equality (which can be proved true by taking the addition of a negative number).

Subtract x from both sides so the answer would be; Y=-x+r
We know that the sum of all angles in any triangle is always 180 and we know that:
The smallest angle = x
Angle 2 = x + 35
Angle 3 = 3 * x
So:
180 = x + x + 35 + 3 * x
180 = x + x + 35 + 3x
180 = 2x + 35 + 3x
180 = 5x + 35 / - 35 (both sides)
145 = 5x / ÷ 5 (both sides)
x = 29
The smallest angle = 29
Angle 2 = 29 + 35 = 64
Angle 3 = 3 * 29 = 87
Check:
29 + 64 + 87 = 180, so it's correct :)
To find the mean you must:
-17 + -14 + -9 + 0 + 12 + 32 + 52 = 56
Then divide 56 by how many numbers are in this set so there are 7 numbers so we divide 56 by 7 and I don't even have to do the work for this because it's basic multiplication.
The answer is: 8.
