Question

Which number sentence is true? A. -3 + 5 = -8 B. -3 – (-5) = -8 C. 3 – 5 = 2 D. 3 – (-5) = 8

Answer 1

Answer:

(D) 3-(-5)=8

Step-by-step explanation:

A. The given equation is:

$-3+5=-8$, but  $-3+5=2$, therefore This option is not correct.

B. The given equation is:

$-3-(-5)=-8$

After solving this, we get

$-3+5=2$ but it is given that $-3-(-5)=-8$, which is not possible, therefore this option is not correct.

C. The given equation is:

$3-5=2$

But after solving the LHS of the equation, we get $3-5=-2$, thus this option is not correct.

D. The given equation is:

$3-(-5)=8$

After solving this equation, we get

$3+5=8$ which is correct. Thus, this option is correct.

Hence, option D is correct.
