2 hamburger + 1 milk =5
1 hamburger + 2 milk =5-.25
1 hamburger + 2 milk =4.75
multiply this by -2
-2hamburger + -4 milk =-9.5
add the first equation
-2 hamburger + -4 milk =-9.5
2 hamburger + 1 milk =5
---------------------------------------
-3 milk = -4.5
divide by -3
milk = 1.50
Answer: milk $1.50
Answer:
D. (2, 5)
Step-by-step explanation:
In order to determine whether an ordered pair is on the graph of a given equation, when we plug the x-coordinate in for x and the y-coordinate in for y, the equation should hold true.
Let's try each of the answer choices:
A. (4, -3)
y = 4x - 3
-3 =? 4 * 4 - 3
-3 =? 16 - 3
-3 =? 13
This is clearly wrong, so eliminate A.
B. (3, 4)
y = 4x - 3
4 =? 4 * 3 - 3
4 =? 12 - 3
4 =? 9
This is clearly wrong, so eliminate B.
C. (1, -1)
y = 4x - 3
-1 =? 4 * 1 - 3
-1 =? 4 - 3
-1 =? 1
This is clearly wrong, so eliminate C.
D. (2, 5)
y = 4x - 3
5 =? 4 * 2 - 3
5 =? 8 - 3
5 =? 5
This is true, so D is the answer.
Our answer is thus D.

Answer:
Laws of Exponents. When multiplying like bases, keep the base the same and add the exponents. When raising a base with a power to another power, keep the base the same and multiply the exponents. When dividing like bases, keep the base the same and subtract the denominator exponent from the numerator exponent.
Step-by-step explanation:
Well not exactly a way to explain the answer.
