Answer: The equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy is 
x= Weight of candy in pounds
0.9x = Weight of milk chocolate.
Step-by-step explanation:
Given, Martin is making a candy that contains 90% milk chocolate and the rest caramels. The candy has 3 pounds of caramels.
Let x= Weight of candy in pounds
Then, 0.9x = Weight of milk chocolate.
Then, According to the question

So, Weight of milk chocolate. = 
Hence, the equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy is 
2.48 / 0.4
Multiply both top and bottom by 10
(2.48 * 10) / (0.4 * 10)
24.8 / 4
6.2
Hope this explains it.
Answer:
u =2
Step-by-step explanation:
5u=18-4u
Add 4u to each side
5u+4u=18-4u+4u
9u = 18
Divide each side by 9
9u/9 = 18/9
u =2
Answer:
1.5
Step-by-step explanation:
The mean is 2.5
1-2.5=1.5
5-2.5=2.5 This is the absolute distance from the mean
3-2.5=0.5
1-2.5=1.5
1.5+2.5+0.5+1.5=6
6/4=1.5
