Answer:
x=16º
Step-by-step explanation:
The sum of angles in a triangle is 180º.
So,
39 + 125 + x = 180
Solve for x.
164 + x = 180
x = 180-164
x= 16
Answer:
Potato
Step-by-step explanation:
1 kg = 1000 g
Assuming the potatoes have the same mass, and the pears have the same mass, then the mass of each potato is:
1000 g / 5 = 200 g
And the mass of each pear is:
1200 g / 8 = 150 g
So a potato has more mass than a pear.

Answer: f(x) = (1/3)x + 3</h3>
This is basically in the form y = mx+b with m = 1/3 as the slope and b = 3 as the y intercept. I'm using f(x) in place of y to indicate function notation.
==========================================
Work Shown:
The goal is to solve for y.
x - 3y = -9
-3y = -9-x ... subtracting x from both sides
-3y = -x-9
y = (-x-9)/(-3) .... dividing both sides by -3
y = -x/(-3) - 9/(-3) ... break up the fraction
y = (1/3)x + 3 .... simplify
f(x) = (1/3)x + 3 .... replace y with f(x)
Apply sum rule:
- 2dx + (x^2 +3x) 6/5dx = x^3dx
2dx = 2x
(x^2 + 3x) 6/5dx = 6/5 (x^3/3 + 3x^2/2)
x^3dx = x^4/4
-2x + 6/5 (x^3/3 + 3x^2/2) - x^4/4
Add constant
-2x + 6/5 (x^3/3 + 3x^2/2) - x^4/4 + c
Here are all the composite numbers in 1-25:
4,6,8,9,10,12,14,15,16,18,20,21,22,24,25 - there are 15 of them in total.
So, 15/25 is 60%.
Hope this helps :p
