Answer:
Step-by-step explanation:
23 divided by X. X=half of 23. but really, you need to add to it. other than that i can't help ya, all i know is that half of 23 is 11.5
The group rent 11 river rent tubes and 4 cooler tubes.
Step-by-step explanation:
Rent for river rent tube = $20
Rent for cooler tubes = $12.50
Total spent = $270
Total tubes rented = 15
Let,
x be the number of river rent tube.
y be the number of cooler tubes.
According to given statement;
x+y=15 Eqn 1
20x+12.50y=270 Eqn 2
Multiplying Eqn 1 by 20
![20(x+y=15)\\20x+20y=300\ \ \ Eqn\ 3](https://tex.z-dn.net/?f=20%28x%2By%3D15%29%5C%5C20x%2B20y%3D300%5C%20%5C%20%5C%20Eqn%5C%203)
Subtracting Eqn 2 from Eqn 3
![(20x+20y)-(20x+12.50y)=300-270\\20x+20y-20x-12.50y=30\\7.50y=30](https://tex.z-dn.net/?f=%2820x%2B20y%29-%2820x%2B12.50y%29%3D300-270%5C%5C20x%2B20y-20x-12.50y%3D30%5C%5C7.50y%3D30)
Dividing both sides by 7.5
![\frac{7.5y}{7.5}=\frac{30}{7.5}\\y=4](https://tex.z-dn.net/?f=%5Cfrac%7B7.5y%7D%7B7.5%7D%3D%5Cfrac%7B30%7D%7B7.5%7D%5C%5Cy%3D4)
Putting y=4 in Eqn 1
![x+4=15\\x=15-4\\x=11](https://tex.z-dn.net/?f=x%2B4%3D15%5C%5Cx%3D15-4%5C%5Cx%3D11)

Answer:
c is the answer
Step-by-step explanation:
Answer:
x 1 = -3
x2 = -3
y1 = 0
y2 = 5
The slope of that equation is infinite and the equation is a perfectly vertical line at x = -3.
So, the equation is x = -3.
