The answer is 319. (638/2=319) square means doubled so you want to find what was double to get the above. So you then would divide by 2 and get your answer.

Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

\left \{ {{3x-5y=19} \atop {x+y=1}} \right.

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

x+(-2)=1\\\\x=1+2\\\\x=3

Therefore, the solution is:

(3,-2)

Josh is putting up a fence around a garden that is next to a wall. He only has 54 feet of fence and the length of the garden mus
vova2212 [387]

Answer:

Length = 12 feet

Width = 30 feet

Step-by-step explanation:

Let l be the length of the garden and let w be the width:

We have system of equations

2w + l = 54

l = 2w + 6

We substitute 2w + 6 for l

2w + 2w + 6 = 54

4w + 6 = 54

4w = 54 - 6

4w = 48

w = 48/4

w = 12 feet

Width(w) = 12 feet

We find the Length

l = 2w + 6

l = 2(12) + 6

l = 24 + 6

I = 30 feet

Complete the table of ordered pairs for the linear y=2x-8
ExtremeBDS [4]

Given:

Consider the below figure attached with this question.

The linear equation is:

y=2x-8

To find:

The values to complete the table of ordered pairs for the given linear equation.

Solution:

We have,

y=2x-8

Substituting x=0 in the given equation, we get

y=2(0)-8

y=0-8

y=-8

So, the value for first blank is -8.

Substituting y=-2 in the given equation, we get

-2=2x-8

-2+8=2x

\dfrac{6}{2}=x

3=x

So, the value for second blank is 3.

Substituting x=2 in the given equation, we get

y=2(2)-8

y=4-8

y=-4

So, the value for third blank is -4.

Therefore, the required complete table is:

     x           y

     0         -8

    3         -2

     2          -4
