Question

What is the answer!!!!!!!!!!

Answer 1

The weight of Jill’s fish is $56{\text{ ounces}}$ and the weight of parakeet is $\boxed{{\mathbf{7 ounces}}}$.

Further explanation:

Given:

It is given that the weight of Jill’s fish is 8 times as much as her parakeet. The total weight of fish and parakeet is  .

Step by step explanation:  

Step 1:

Consider $x$ as the weight of parakeet.

It is given that the weight of Jill’s fish is 8 times of the weight of parakeet.

Therefore, the weight of Jill’s fish can be expressed as $8x$.

Step 2:

The total weight of fish and parakeet is $63{\text{ ounces}}$.

Now make an equation for the total weight of fish and parakeet both as,

$x + 8x = 63$  

Now solve the equation $x + 8x = 63$ to obtain the value of $x$.

$\begin{aligned}x + 8x &= 63 \\9x &= 63 \\\end{aligned}$  

Now divide the resultant equation by 9 to obtain the value of $x$.

$\begin{aligned}\frac{9}{9}x&= \frac{{63}}{9} \\x &= 7 \\\end{aligned}$  

Therefore, the weight of parakeet is $7{\text{ ounces}}$.

Step 3:

Now find the weight of Jill’s fish that is $8x$ where $x$ is the weight of parakeet.

Now substitute the value of $x = 7$ in the expression $8x$ to obtain the weight of Jill’s fish as,

$\begin{aligned}{\text{weight of fish}} &= 8x \\& = 8 \times 7 \\&= 56 \\\end{aligned}$    

Therefore, the weight of Jill’s fish is $56{\text{ ounces}}$and the weight of parakeet is $7{\text{ ounces}}$.

Answer 2

The fish weigh is 56 ounces

Further explanation

To solve this problem, first step would be create two variables, x and y as follow:

x = fish weight

y = parakeet weight

Given:

From the problem above we can make two equations which are

x = 8y                    ⇒ first equation

x + y = 63              ⇒ second equation

The first step, we will substitute the first equation into the second equation to get the y variable:

x + y = 63

8y + y = 63

9y = 63

y = 7

then we substitute the y=7 into the second equation (either 1st or 2nd equation)

x + y = 63

x + 7 = 63

x = 56

So, jill's fish weigh is 56 ounces
