Answer:
b. at least one person has done a one-time fling
Step-by-step explanation:
Find the first derivative and evaluate at <span><span>f<span>(x)</span></span><span>f<span>(x)</span></span></span>.<span>gg</span>and then found out what the answer is
To solve this question, we should set up a system of equations. Let a represent the number of passengers on bus 1 and b represent the number of passengers on bus 2.
From the question, we can set up the two equations:
1/3(a+b)=24
a=34
To solve this system, it is easiest to substitute the value we know for a into the first equation. If we do this, we get:
1/3(34+b)=24
To simplify this equation, we need to divide both sides by 1/3 in order to get the variable b alone. After simplifying, we get the equation:
34 + b = 72
Finally, we subtract 34 from both sides to get the variable b alone.
b = 38
Therefore, there were 38 passengers on bus 2.
Hope this helps!
G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
