Answer:
I think it's the third one
Step-by-step explanation:
A = first number (larger number)
b = second number (smaller number)
a = 8b
a - b = 70 *
* since a is the larger number and their difference is positive, we want a-b.
plug the first equation into the second to get :
a - b = 70
(8b) - b = 70
8b - b = 70
Your correct answer would be choice #2.
Step 1. multiply the bottom to the other side
3=(5x+5)/(11)
Step 2. multiply the eleven to the other side
33=(5x+5)
Step 3. subtract the 5 to the other side
28=5x
Step 4. divide by 5
x=28/5 or 5.6

For this case we have the following expression:
6q / 20 (q + r)
Rewriting the expression we have:
(6/20) (q / (q + r))
Simplifying we have:
(3/10) (q / (q + r))
Answer:
The simplified expression is given by:
(3/10) (q / (q + r))
