I think the answer would be $9.46 left as a tip for the waiter.
Answer:
y=-15x+b
Step-by-step explanation:
Just move it around and use a calucator
Answer:
c + ab
Step-by-step explanation:
The way an expression is written is the given you have presented to us.
The commutative law of addition would turn it around as
c + ab.
It just means change the order when adding. Not all systems allow this. It matters which way you put it in some systems.
Short leg = ?
Long leg = 1/2x + 11
Hypotenuse = 2x + 1
For this you'd need to use the Pythagorean Theorem to find the short leg.
Pythagorean Theorem - a^2 + b^2 = c^2
If you use the square root and put it in (-1-2)^2+(4--9)^2 it will equal = 13.34166406
