Answer:
f(2/9) = 1
Step-by-step explanation:
f(x) = 3x + 1/3........find f(2/9)...so sub in 2/9 for x
f(2/9) = 3(2/9) + 1/3
f(2/9) = 6/9 + 1/3
f(2/9) = 2/3 + 1/3
f(2/9) = 3/3
f(2/9) = 1 <=====
The missing term would be 36

Step-by-step explanation:
In the system of equations, x represents the, price to wash a car and y represents the price to wash an SUV.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.
x=12 and y = 18
x+y = 12+18 = 30
The total cost of 1 car and 1 SUV is $_30____.
5x+4y = 5(12)+4(18) = 60+ 72 =132
The total earnings for hour 3 are $_132_____.

Step-by-step explanation:
Let x = cost of bill prior to tip
So, we know that before a tip was paid that the cost of the meal was $46.25. If there were three people at the dinner and we are trying to find the average spent <em>prior</em> to the tip, we can just divide.
Let a = average each person spent
On average, prior to the bill, each person paid approximately $15.42.
