Answer:
The amount of weight he has lost in 3 months is 1.215 stone or 1 stone 3 pounds
Step-by-step explanation:
From the above question, we are to calculate the amount of weight he has lost in three months
1 stone = 14 pounds
Let's convert all the weight lost to stone
At the start of the diet keirin weighted 14 stone 13 pounds
14 pounds = 1 stone
13 pounds = x
Cross Multiply
14x = 13
x = 13/14
x = 0.9285714286 stone
Approximately = 0.929 stone
Hence:
14 stone 13 pounds = 14 + 0.929 = 14.929 stone
Three months later he weighted 13 stone 10 pounds
14 pounds = 1 stone
10pounds = x
Cross Multiply
14x = 10
x = 10/14
x = 0.7142857143 stone
Approximately = 0.714 stone
Hence:
13 stone 10 pounds = 13 + 0.714 = 13.714 stone
The amount of weight he has lost is calculated as:
14.929 stone - 13.714 stone = 1.215 stone or 1 stone 3 pounds
Step-by-step explanation:
![\frac{y_2-y_1}{x_2-x_1}=\frac{15-(-13)}{28-(-28)}\\=\frac{28}{2(28)}\\\therefore\ m=\frac{1}{2}\\\frac{y-y_1}{xl-x_1}=m]\\\frac{y+13}{x+28}=\frac{1}{2}\\2y+26=x+28\\2y=x+2\\ y=\frac{1}{2}x+1](https://tex.z-dn.net/?f=%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cfrac%7B15-%28-13%29%7D%7B28-%28-28%29%7D%5C%5C%3D%5Cfrac%7B28%7D%7B2%2828%29%7D%5C%5C%5Ctherefore%5C%20m%3D%5Cfrac%7B1%7D%7B2%7D%5C%5C%5Cfrac%7By-y_1%7D%7Bxl-x_1%7D%3Dm%5D%5C%5C%5Cfrac%7By%2B13%7D%7Bx%2B28%7D%3D%5Cfrac%7B1%7D%7B2%7D%5C%5C2y%2B26%3Dx%2B28%5C%5C2y%3Dx%2B2%5C%5C%20y%3D%5Cfrac%7B1%7D%7B2%7Dx%2B1)
