A.)Rachel should have 6 second class tramps. Because if you do the equation 6+6+6 you get 18 (the number of first class stamps she has)
2.)Add 6 to 18 to get your answer :)
Answer: 16y² - x²
Step-by-step explanation: The - sign means a difference, so the choices with + signs are eliminated (though 64x² and 9 are squares)
10 is not a square so that one is eliminated (though the y² and the 4x² are squares)
16 is the square of 4, y² is the square of y, and x² is the square. That expression shows a difference of squares.
Answer:
1. x = -3
2. x = 4/3
3. x = 698/77
Step-by-step explanation:
4+2x=-2
-4 -4
2x= -6
/2 /2
x=-3
You have to get x alone on one side. Search up on yt "How to solve for x on two sides."
