Answer: 4
Step-by-step explanation:
First you make your equation
3d=12
Divide
You get d=4
Therefore each person pays 4 dollars of the 12 dollar tip
Right, because it has two even sides for the right and angle and the right is a hypotenuse.
Answer:
2x-2=-4
5/8x3/5= 15/40 then u simplify and get -4 3/8
Answer:
x=-2, y=-6
Step-by-step explanation:
Simple substitution.
Since y is isolated in one of the equations already, you can plug it into the second equation.
x - 2(3x) = 10
x - 6x = 10
-5x = 10
x = -2
Sub. x = -2 into 3x = y:
3(-2) = y
y = -6
