To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that
X + 14 - 14 = 56 - 14
X=42
Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.

He must sell more than $1058. First find the difference and multiply that by 20 (100/5) to find the necessary amount.
O to A = (-8,2)(0,0) = (0 - (-8) / (0 - 2) = -8/2 = -4
A to B = (-12,3)(-8,2) = (2 - 3) / (-8 - (-12) = -1/4
so O to A is 4 times the slope of A to B
=====================
initial value is the y int....5
====================
(0,200)(1,160)
slope = (160 - 200) / (1 - 0) = - 40
u have a y int of 200
ur equation is : y = -40x + 200
==================
(0,25)(1,40)
slope = (40 - 25) / (1 - 0) = 15
y = mx + b
slope(m) = 15
(0,25)...x = 0 and y = 25
sub and find b
25 = 15(0) + b
25 = b <=== this is ur fixed amount
We know that 172 of them were wood, so the rest are metal. To find that number we do:
276 - 172 = 104 metal pins.
To find the percentage that they were metal, take the number of metal pins and divide by the total number of pins:
104/276 is about 0.3768.
Multiply this by 100:
37.68
So, the percent of metal pins is 37.68%.
