2 numbers a and B are graphed on a number line is it always sometimes or never true

1 answer:

4 0

The answer is "sometimes".

If A = 3 and B = 1 then, A > B and A-B < A+B

On the other hand, If A = 3 and B = -1, then A > B but A-B is not less than A+B.

Alex

Answer:

The number of movies purchased is 5

Step-by-step explanation:

40.00 + 3.50 = 43.50

43.50 + 3.50 = 47.00

47.00 + 3.50 = 50.50

50.50 + 3.50 = 54.00

54.00 + 3.50 = 57.50

so if you add 3.50 to 40, 5 times you'll get 57.50
