This is how you would write the statement:

You could also write it like this, if the one-half applies to everything:
Answer:
23 should have been subtracted from, not added to, both sides of the equation.
Answer:
A.The expression represents the price paid
B.
; everything means the same thing as the first.
Step-by-step explanation:
For a. we can tell what the expression means by re-reading the problem. We know that the 15 is the price per goby fish and that 10 is the price per shrimp. Since there is an equal number of each in each bag the x represent the number of goby fish or shrimp in the bag. The answer to the equation will be the price paid. Another expression you could use is the following.

This is an unfactored version of the first on where x is factored out. Here everything means the same thing it's just a different expression.
Lets set up an equation to easier understand this.
1/1.5 = 3.7/x (x represents the unknown km)
We know that whatever you do to the top you do to the bottom.
And we can see that 1 x 1.5 = 1.5
So we can multiply the same thing by 3.7
1.5 x 3.7 = 5.55
<u>So in this case you would travel 5.55 km in 3.7 seconds. </u>
GOOD LUCK :)
A mathematical expression which best represents the perimeter of this triangle is (15h - 6k + 12m) centimeters.
<u>Given the following data:</u>
