X + 12 = 13
x = 13 - 12
x = 1
The only solution is x = 1
letter B
Answer:5.4×105+2.3×104.
Step-by-step explanation:
No they cant because 20 is not divisible by 75. One option that would work is 15 rows each with 5 people or vise versa. Hope this helped!
If you can manipulate the two equations so that they have exactly the same coefficients (e. g., 3x + 4y = 8 and 2x + 4y = 8), then you conclude that the two lines coincide (overlap), and that there are thus infinitely many solutions.
by dy/dx, we'll be assuming that "y" is encapsulating a function, a function in terms of "x".
