Question

What is the value of the expression when q = 8, r = 1, and s = 3? q/2r−s

Answer 1

Hello,

To solve this mathematical question, simply substitute the values of each known variable into the expression q/2r-2.

q = 8,

r = 1

s = 3

Therefore:

8/2(1)-2

Use the order of operation (PEMDAS) to solve :

2*1=2

Refined:

8/2-2

8/2 = 4

Refined:

4-3= 1

Thus, q/2r-s equals 1.

Your answer is option one: 1.

Faith xoxo

Answer 2

(q/2•r)-s we substitute q=8, r=1 and s=3
(8/2•1)-3
4-3
