Okay so let’s say the permit fish is the variable p.
The tarpon is 11p.
So, to set up the equation,
(11p)+p=168
Start by combining like terms on the left
12p=168
Divide both sides by 12 to isolate p
p=14
So therefore, the permit fish was 14 pounds.
To find the weight of the tarpon, insert the 14 back into (11p) 11(14)=154.
You can check by adding these together 14+154=168
So:
The permit fish weighed 14 pounds.
The tarpon weighed 154 pounds.
Hope this helps!
The equation would be 15 + x2 = 33. In this case, x would be 9. 9 times 2 is 18, and 18 plus 15 is 33.
Answer:
Step-by-step explanation:
Let's define some notation first:
represent the number of grapges that we buy
represent the amount of money that we have in order to pay
represent the unitary cost per each pound of grapes. This value sia assumed because is not logic that a pound of grapes cost $41.29.
represent the change
Solution to the problem
In order to find a function to the change we need to satisfy the following equation:
Because the change plus the ocost needs to be equal to the total amount.
If we solve for the change r we got this function:
And if we replace the values for A and C we got:
And this would be our function for the change based on the info provided.
