20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.
Answer:
y = 3 - 2x
Step-by-step explanation:
The goal is to isolate the y variable
In order to have y by itself (on one side of the equation or equal sign), we must move the other numbers and variables to the other side.
Since 2x is on the same side as y, we have to subtract it from both sides. Subtracting it cancels out the original 2x and leaves the equation to look like this:
y = 3 - 2x
Now the y is isolated
Another example:
-5x + y = 15
To isolate the y, we must cancel out the -5x. Add 5x to both sides. It will cancel out the -5x and bring it to the right side of the equation, resulting in:
y = 15 + 5x
Answer:

Step-by-step explanation:
The total amount of shrimp that was eaten was 12 pieces of shrimp.
To make the fraction you will simply put the amount of shrimp Jeremy ate over the total number of shrimp eaten by the pair.
Therefore, the fraction would look like this:

The decimal form of this would be 0.4167. Which also means that Jeremy ate 41.67% of the total amount of shrimp eaten.
Hope this helps!!
11 / 26 = 42% This answer is certainly correct for your percentage.
Answer:
25n^8
Step-by-step explanation:
Area of a square is length×length
Length=5n^4
Area=5n^4×5n^4
=(5×5)(n^4+4)
=(25)(n^8)
=25n^8
So the area of a square is 25n^8
