Law of Detachment means 1. if p then q and 2. p then we can derive a 3rd true statement 3. q
Law of Syllogism means that if the following two statements are true 1. if p then q. 2. if q then r. Then we can derive a third true statement 3. if p then r.
So the difference is one has only p and q and the other has p q and r.
Answer:
You will break even on the car wash when you buy 13.5 gallons. As long as you buy that or more, it is cheaper to get the car wash.
Step-by-step explanation:
In order to find this, we need to create equations for both situations. If we let x equal the amount of gallons purchased, we can model the first equation as:
f(x) = 3.35x
And the second equation as:
f(x) = 3.05x + 4.05
Then to find when they equal each other, we can set the two equations equal to each other and solve for x.
3.35x = 3.05x + 4.05
0.30x = 4.05
x = 13.5
This means once you buy 13.5 gallons, the prices will be the same. Any amount over that and the car wash will be cheaper

Answer: -5 and -1
Step-by-step explanation:
-5 * -1 = 5
-5 + -1 = -5 -1 = -6
The scale factor is 1/22.
In the drawing, the height of the school shows 1.6 feet.
In order for us to know the actual height, we can have it as.
1.6 = Height of school * (1/22)
1.6 = Height of school / 22
Height of school = 35.2
So the actual height of the school is 35.2 feet.
