Step-by-step explanation:
I think your supposed to add all those numbers together
Answer:
The equation for this sentence is: 9 = 2(4y)
45 / 2 = 22.5
You can get 22.5 hours of Internet for 45$.
Answer:
The second option: 3 (6 - 5n)/20n
Step-by-step explanation:
Make sure all fractions have a common denominator:
Step 1. Find a common multiple between all three denominators
5, 4, and 10 all have a common multiple of 20. Proof: 5 × 4 = 20, 4 × 5 = 20, and 10 × 2 = 20
Step 2. Multiply the denominators to get to 20. Whatever you do to the bottom (denominator) must be done to the top (numerator).
1/5n × 4/4 = 4/20n
3/4 × 5n/5n = 15n/20n
7/10n × 2/2 = 14/20n
Your fractions now all have a common denominator of 20n.
Rewrite the equation using the new fractions:
4/20n - 15n/20n + 14/20n
Only focus on adding/subtracting the numerators; the denominators will stay the same: 20n.
(4 - 15n + 14)/20n
Combine like terms:
(18 - 15n)/20n
Factor out any numbers possible:
3(6 - 5n)/20n
Note* 3 go into both 18 and 15, which allows us to factor 3 out. 18 ÷ 3 = 6 and 15 ÷ 3 = 5, giving us our new numbers inside the parentheses.
Hwong could fill 12 packets of coffee in small boxes:
He has 10 boxes, so 10 x 12 = 120 packets total
Hwong's packets of coffee in the large boxes:
He can fit 50 packets into the boxes, so 120/50 = 2 large boxes and a remaining 20 packets of coffee
Therefore, Hwong can fit 12 packets of coffee to 1 small box and 8 packets to the other small box
