Your two systems will be
8A + 3S = 79$
your 2nd will be
10A + 5S = 105$
The formula to find the x coordinate is -b/2a. If you plug in the variables
-5/2(2) = -5/4 = -1.25
x = -1.25
Now plug in x into the y equation.
y = <span>-11.125</span>
P = 1/2 x 1/2
P = 1/4 or 25%
Answer:
1 hour and 7.5 minutes
Step-by-step explanation:
We have the following information:
Jose makes 1 / 1.5 of the job per hour. It is his rate of work in addition to that the partner makes 1 / 4.5 of the job per hour. It is his rate of work.
Thus:
1 / 1.5 + 1 / 4.5 = 1 / x
0.8898 = 1 / x
x = 1 / 0.8888
x = 1.125
Hence, it will take 1 hour and 7.5 minutes for them to complete the job working together.
