Select all of the following statements that are true.

Ivanshal [37]

Answer:

A, B, C, D, F (or all but the second to last one)

Step-by-step explanation:

Let's look at each of these problems

A. $-\frac{3}{4} + \frac{3}{4} = 0 = 0 = True$

B. $-\frac{3}{4} + 0 = -\frac{3}{4} = -\frac{3}{4} = True$

C. $-\frac{3}{4} + \frac{3}{4} = \frac{3}{4} + (-\frac{3}{4} ) = (-\frac{3}{4} ) = True$

D. $-\frac{3}{4} - \frac{3}{4} = -(\frac{3}{4} + \frac{3}{4} ) = -(\frac{6}{4} ) = True$

E. $-\frac{3}{4} + \frac{3}{4} = 0 \neq (-\frac{3}{4}) = False$

F. $\frac{3}{4} -\frac{3}{4} = \frac{3}{4} + (-\frac{3}{4}) = 0 = True$

Hope this helped!
