Answer:
A positive number
Step-by-step explanation:
3 * 1/3 = 1.
the multiplicative inverse of 3 is 1/3.
5x + 2/2 = 2x - 1
2/2 is basically 1 so
5x + 1 = 2x - 1
isolate the variable
5x + 1 = 2x - 1
-1 -1
5x = 2x -2
-2x -2x
3x = -2
solve
3x/3=-2/3
x=-2/3
The bakery had 54 loaves of bread in the morning. You can prove this by adding the 21 loaves of bread to the seven they have left, then multiplying it times two because it sold half the bread in the morning.
3. 2z + 7 = -5
2z = -12
z = -6
4. B
5. infinitely many solutions
6. one solution
