We have,
14 wings = 9 wytes
=> 1 wings = 9/14 wytes --- (1)
and,
9 wongs = 7 wings
=> 9 wongs = 7 × 9/14 wytes [from (1)]
=> 9 wongs = 9/2 wytes
=> 9 × 2/9 wongs = 1 wytes
=> 2 wongs = 1 wytes
hence 2 wongs makes a wyte
Step-by-step explanation:
Points are (8,5) and (-12,-9)
The equation of a line passing through two points is given by :
![y-y_1=m(x-x_1)\ \text{m is slope}\\\\y-5=\dfrac{y_2-y_1}{x_2-x_1}(x-8)\\\\y-5=\dfrac{-9-5}{-12-8}\times (x-8)\\\\y-5=\dfrac{7}{10}\times (x-8)\\\\10y-50=7x-56](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29%5C%20%5Ctext%7Bm%20is%20slope%7D%5C%5C%5C%5Cy-5%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-8%29%5C%5C%5C%5Cy-5%3D%5Cdfrac%7B-9-5%7D%7B-12-8%7D%5Ctimes%20%28x-8%29%5C%5C%5C%5Cy-5%3D%5Cdfrac%7B7%7D%7B10%7D%5Ctimes%20%28x-8%29%5C%5C%5C%5C10y-50%3D7x-56)
or
![-50+56=7x-10y\\\\7x-10y=6](https://tex.z-dn.net/?f=-50%2B56%3D7x-10y%5C%5C%5C%5C7x-10y%3D6)
But he writes the equation 7x – 10y = 3 which is not matching with the one we have calculated. It means that model calculated by Devon is not good.
Let
a--------> the total cost in dollars of
ounces of coconut oil
b--------> the total cost in dollars of
ounces of beeswax
we know that
![a=0.50 \frac{\$}{ounce}*6=\$3](https://tex.z-dn.net/?f=a%3D0.50%20%5Cfrac%7B%5C%24%7D%7Bounce%7D%2A6%3D%5C%243)
![b=2.00 \frac{\$}{ounce}*5=\$10](https://tex.z-dn.net/?f=b%3D2.00%20%5Cfrac%7B%5C%24%7D%7Bounce%7D%2A5%3D%5C%2410)
therefore
<u>the answer is</u>
the total cost in dollars of
ounces of coconut oil is ![a=\$3](https://tex.z-dn.net/?f=a%3D%5C%243)
the total cost in dollars of
ounces ofbeeswax is ![b=\$10](https://tex.z-dn.net/?f=b%3D%5C%2410)
1 cm = 10 millimetres
10 cm = 100 millimetres
100 cm = 1,000 millimetres = 1 metre
Therefore:
4 metres = 4,000 millimetres
