Answer:
k = 8
Step-by-step explanation:
We know that 8(10-k) = 2k so:
8(10−k)=2k
<u>Simplify both sides of the equation:</u>
8(10−k)=2k
(8)(10)+(8)(−k)=2k
80+−8k=2k
−8k+80=2k
<u>Subtract 2k from both sides:</u>
−8k+80−2k=2k−2k
−10k+80=0
<u>Subtract 80 from both sides:</u>
−10k+80−80=0−80
−10k=−80
<u>Divide both sides by -10:</u>
k = 8
The cooper's weight as an adult dog will be 90 pounds.

What is percentage?</h3>
Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolized as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.
A typical method for calculating a percentage is the formula shown below:
- Determine the total amount of what you want to find a percentage.
- Divide the number to determine the percentage.
- Multiply the value by 100.
Calculation for the weight of Cooper as an adult;
Cooper's present weight is 20 pounds.
He will weigh about 350% as much as his current weight.
Calculate 350% of 20 pounds.
= (350×20)/100
= 70
The increment of the weight of Cooper will be 70 pounds.
Thus, the total weight is 20 + 70 = 90.
Therefore, the weight of Cooper after 350% as an adult would be 90 pounds.
