Sam is fencing in his property. The length is 12 feet less than twice the width. If the total amount of fence needed is 216 feet

DaniilM [7]

Answer:

L = 68 ft

Step-by-step explanation:

To find the perimeter of something you need to add up all the sides

In this case I am assuming Sam's property is a square/rectangle

Which means the formula for the perimeter is P = 2L + 2W

If L = 2W - 12 and P = 216, we can use these values and plug them into our perimeter equation to solve for w and then solve for l

216 = 2(2W -12) + 2W → ditributing the 2 to the (2w - 12) gives us
216 = 4W - 24 + 2W → combing like terms gives us
216 = 6W - 24 → adding 24 to both sides gives us
240 = 6W → dividing both sides by 6 gives us
40 ft = W

With the width being solved, we can now plug that value into our length equation

L = 2(40) - 12 → distributing the 2 to the 40 gives us
L = 80 - 12 → combing like terms give us
L = 68 ft

A copy machine can print 340 color copies every 8 minutes. Explain or show your reasoning.

mylen [45]

Step-by-step explanation:

340=8min

850=?(x)

340x=850×8

340x=6800

x=6800/340

x=20min

so..the teachertook 20 minute to print 850 copies

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define Systems

-2x + y = 0

5x + 3y = -11

Step 2: Rewrite Systems

-2x + y = 0

Add 2x on both sides: y = 2x

Step 3: Redefine Systems

y = 2x

5x + 3y = -11

Step 4: Solve for x

Substitution

Substitute in y: 5x + 3(2x) = -11
Multiply: 5x + 6x = -11
Combine like terms: 11x = -11
Isolate x: x = -1

Step 5: Solve for y

Define equation: y = 2x
Substitute in x: y = 2(-1)
Multiply: y = -2

Step 6: Graph Systems

Check the solution set.
