Answer:
45 sweets.
Step-by-step explanation:
6:2:1
To solve how many Jim and Dan has I did 6 x n and 1 x n until the difference of the two numbers equaled 25.
6 x 5 = 30
1 x 5 = 5
30 - 5 = 25.
So, Jim as 30 candy and Dan has 1. How much does David have?
Just do the same thing but with 2 x n:
2 x 5 = 10.
Now add them together:
30 + 10 + 5 = 45.
Therefore, 45 sweets!
Need a common denominator.
Use 36.
Multiply the denominators by each other.
45/36 + 28/38 add the top!
73/36 or 2 and 1/36

Answer:
0u
7u
6u
2u
Step-by-step explanation:
All of these question are just a matter of adding like terms
For the first one we have
7u+(-u)+(-6u)
which is equal to
7u-u-6u
Which I'm sure you can see is equal to 0 or 0u
10/2u+2u
10/2u=5u
5u+2u=7u
6u+0u
0u=0
6u
6u+(-4u)
6u-4u
2u
