Answer:
14/5
Step-by-step explanation:
I'd suggest rewriting both mixed numbers as improper fractions. Then we'd have:
14/3 and 5/3
Dividing 14/3 by 5/3 is equivalent to dividing 14 by 5, since the denominators are the same (3).
Quotient is 14/5.
Answer:
Where is the info so we can show you
Step-by-step explanation:
Answer: 3r + 2b = 24
r + 3b = 16
Step-by-step explanation:
Let the red blocks be represented by r
Let blue blocks be represented by b
Since 3 red blocks and 2 blue blocks weigh 24 ounces. This will be:
3r + 2b = 24
1 red block and 3 blue blocks weigh 16 ounces. This will be:
r + 3b = 16
Therefore, the equation will be:
3r + 2b = 24
r + 3b = 16
