MD
Step-by-step explanation: hope this helps :)

let us first plug the values of r and s here
r=14 and s=8

Now here we can cancel 14 and 7 as 7*2 =14 , also we can cancel 8 and 8 as 8*1 is 8, so our simplified new form is:

Now we can multiply 3*2 and 5*1
3*2 =6
5*1=5
Next we add the two numbers
6+5 =11
So this is how we get the answer 11
The answer is C.
39-5/ 21-4 = 2
Answer:
2138.85
Step-by-step explanation:
2250 decreased by 2% is
2% of 2250 subtracted from 2250
That’s
2% /100% x 2250
0.02 x 2250
45
So, decrease = 2250 - 45
= 2205
Now 2205 decreased by 3%
3% of 2205
3% /100% x 2205
0.03 x 2205
66.15
Decrease = 2205 - 66.15
= 2138.85
