<h3>Answer: 8x+3y = 16</h3>
============================
Work Shown:
x = number of hours spent running
8x = distance he runs (since he runs at 8 mph)
y = number of hours spent walking
3y = distance he walks (he walks at a speed of 3 mph)
8x+3y = total distance = 16 miles
8x+3y = 16
This equation is in standard form Ax+By = C
--------
Extra Info
Solving for y will get
8x+3y = 16
3y = -8x+16
y = (-8x+16)/3
y = (-8x)/3+16/3
y = (-8/3)x+16/3
This is in slope intercept form y = mx+b
m = -8/3 is the slope
b = 16/3 is the y intercept
Answer:
The variable cost per unit is calculated by dividing the total variable costs of the business by the number of units.

A of the shaded figure is 90cm
Answer:

Explanation:

Compute:
35 ÷ 16 = 2.1875 = 2R3
2 ÷ 16 = 0.125 = 0R2

Let's look at another example: ![\sf 325_{10} = [?]_{16}](https://tex.z-dn.net/?f=%5Csf%20325_%7B10%7D%20%3D%20%5B%3F%5D_%7B16%7D)
Compute:
325 ÷ 16 = 20.3125 = 20R5
20 ÷ 16 = 1.25 = 1R4
1 ÷ 16 = 0.0625 = 0R1
Jot down remainders:
=====
![\sf 325_{10} = [145]_{16}](https://tex.z-dn.net/?f=%5Csf%20325_%7B10%7D%20%3D%20%5B145%5D_%7B16%7D)

Another example: ![\sf 500_{10} = [?]_{15}](https://tex.z-dn.net/?f=%5Csf%20500_%7B10%7D%20%3D%20%5B%3F%5D_%7B15%7D)
Compute:
500 ÷ 15 = 33.33... = 33R5
33 ÷ 15 = 2.2 = 2R3
2 ÷ 15 = 0.13... = 0R2
Jot down remainders:
=====
![\sf 500_{10} = [235]_{15}](https://tex.z-dn.net/?f=%5Csf%20500_%7B10%7D%20%3D%20%5B235%5D_%7B15%7D)
