Answer:

Step-by-step explanation:

let length of first piece = x in

length of second piece = 2x

length of third piece = 5x

x+2x+5x= 16

8x =16

x =16/8

x=2

length of :

first piece =2 inches

second piece = 4 inches

third piece = 10 inches..

Answer:

2, 4, 10 in

Step-by-step explanation:

The first piece is x thus the second piece is 2x ( twice as long as first ) and

the third piece is 5x ( five times as long as the first )

Add the 3 together and equate to 16

x + 2x + 5x = 16, that is

8x = 16 ( divide both sides by 2 )

x = 2

Thus

first piece = x = 2 in

second piece = 2x = 2 × 2 = 4 in

third piece = 5x = 5 × 2 = 10 in

Pani-rosa [81]

Answer: 4.5

Step-by-step explanation:

S= ut + 1/2(at)

S= 10(1/2) + 1/2(-2x1/2)

S= 5 + 1/2(-1)

S= 5 + (-.5)

What is the answer????
Liula [17]

Answer:

(5, 6)

Step-by-step explanation:

<u>Step 1:  Solve for x in the first equation </u>

x - y + y = -1 + y

x = y - 1

<u>Step 2:  Plug in x into the second equation </u>

(y - 1) - 3y = -13

y - 1 - 3y + 1 = -13 + 1

-2y / -2 = -12 / -2

y = 6

<u>Step 3:  Plug in y into the first equation </u>

<u />x - (6) + 6 = -1 + 6

x = 5

Answer:  (5, 6)

If you were solving a system of equations and you came to a statement like 1 = 3, what do you know about the solution to the sys
noname [10]
<h2>Key Ideas</h2>
  • Systems of equations

<h2>Solving the Question</h2>

When both sides of the equal sign are equal, there are infinite solutions.

When you are able to isolate the variable, there is only one solution.

When the equation states an untrue expression, there is no solution.

1=3 is an untrue fact. Therefore, there would be no solutions to the system.

<h2>Answer</h2>

There is no solution
