Answer:
39 dimes
Explanation:
From the graph:
• Total number of nickels = 9+4+7=20
,
• Total number of dimes = 7+10+9 = 26
The ratio of total nickels to total dimes = 20:26
If the total number of nickels the students donate is increased to 30, we have:

We then solve for x:

The number of dimes they should donate to keep the ratio of total nickels to total dimes the same is 39.
Answer:
n = 2.5 or n = (5/2)
Step-by-step explanation:
(2n+4) +6 = -9 + 4(2n+1)
first distribute the 4 to the (2n+1)
(2n+4) +6 = -9 + (8n+4)
then add 9 to both sides to cancel out the -9 on the right side
(2n+4) +15 = (8n+4)
next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract
15 = 6n
then divide 15 by 6 to get your final answer
n = 2.5
or
n = (5/2)
