Dr. Hoover allot his time on Tuesday for an annual checkup is 147 minutes and for a sick visit is 42 minutes (Total 189 minutes)
On Wednesday appointment, he allot his time for an annual checkup is 147 minutes and for a sick visit is 21 minutes (Total 168 minutes)
solution
Let us assume, minutes for annual checkup denoted as x and
minutes for sick visit denoted as y
The equation of Tuesday visit is ![3x + 2y = 189 minutes ------ 1](https://tex.z-dn.net/?f=3x%20%2B%202y%20%3D%20189%20minutes%20------%201)
The equation of Wednesday visit is ![3x + 1y = 168 minutes ------ 2](https://tex.z-dn.net/?f=3x%20%2B%201y%20%3D%20168%20minutes%20------%202)
by changing the signs of the equation 2 and subtract it from the equation 1 we will get 1y = 21 minutes
to substitute y =1 in the equation 2 we get
![3x + 2(21) = 189](https://tex.z-dn.net/?f=3x%20%2B%202%2821%29%20%3D%20189)
![3x + 42 = 189](https://tex.z-dn.net/?f=3x%20%2B%2042%20%3D%20189)
![3x = 189 - 42](https://tex.z-dn.net/?f=3x%20%3D%20189%20-%2042)
![3x = 147](https://tex.z-dn.net/?f=3x%20%3D%20147)
![x = 147 ÷ 3 = 49 minutes](https://tex.z-dn.net/?f=x%20%3D%20147%20%C3%B7%203%20%3D%2049%20minutes)
then now we have substitute both x = 49 and y= 21 in equation ----- 2
we will prove that
![147+ 42 = 189 minutes](https://tex.z-dn.net/?f=147%2B%2042%20%3D%20189%20minutes)
so the Tuesday appointment , the time allotted for an annual checkup is 147 minutes and for a sick visit is 42 minutes (Total 189 minutes)
On Wednesday appointment, the time allotted for an annual checkup is 147 minutes and for a sick visit is 21 minutes (Total 168 minutes)
Answer:
equation of the line that passes through (2,7) and (7,12) is y=x+5
The answer would be 7/3. You would divide them both by 3. You just divide them by the same number to the point were you cant divide both by the same number anymore. For example 18/9 you can divide it by 2 to get 2.
the answer is 96 69 all the
time
