2x - 5x= -3x + 6x = 3x
7 + 14 = 21
3x + 21
To -120 feet all you have to do is multiply (-15) times 8
Answer:
B. and C. both equations has infinitely many solutions.
Step-by-step explanation:
- B. 3(4y-5)=12y-15 → 12y-15=12y-15
- C. 4(5y+2)=20y-6 → 20y+8=20y-6
In both the equations, value of y cannot be determined, so they have infinitely many solutions.
Answer:
The answer is 9 5/12
Step-by-step explanation:
Convert both to improper fractions, then change the denominator to 12, add them, and change back to Mixed Fraction
