The length of a rectangle is twice the width. The perimeter is 25. The system to help find the length and width is:
L=2W

2L+2W=25

Aaron tried using a graph to find the measurements but was unsure of the exact values. Use substitution to solve the system exactly. Round to the nearest hundreth.

Answers

9514 1404 393

Answer:

  (L, W) ≈ (8.33, 4.17)

Step-by-step explanation:

Substituting for L, we have ...

  2(2W) +2W = 25

  6W = 25

  W = 25/6 ≈ 4.17

  L = 25/3 ≈ 8.33

The rounded "exact" solution is ...

  (L, W) = (8.33, 4.17)

Let the width be x
Since the question mentions the length is twice the width,
let the length be 2x
The total perimeter given is 25cm and as we know, perimeter for a rectangle :
=> P = 2(Length + width)
So,

25cm = 2(2x + x)
25 = 4x + 2x
25 = 6x
25/6 = x
4.166666667 = x

Choose the correct answer

Answers

Answer:

Its c. c = 50.

Step-by-step explanation:

First, we need to figure out what the equation equals.

7 + 7/7 + 7*7 - 7 = x

PEMDAS

Parentheses, exponents, division/fraction, addition, subtraction.

7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.

7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.

Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.

c is the only one who has a calculation of 50.

Your answer is (3, -4) .. to get that I plugged each set into the equation and solved to figure out which ordered pair makes this statement equivalent.. I got 13=13 after plugging in and solving so that makes it equivalent the other ordered pair makes an inequivalent outcome which was 9=13 ... I hope this helps

Simplify the expression (2.5x − 5) − ((7x − 9.7)).

Answers

Answer:

−4.5x+4.7

Step-by-step explanation:

The value of the expression (2.5x − 5) − ((7x − 9.7) is 4.5x - 4.7.

In order for us to simplify the expression (2.5x − 5) − ((7x − 9.7)), we simply have to open the brackets and collect like terms. This will be:

= (2.5x − 5) − (7x − 9.7)

= 2.5x - 5 - 7x + 9.7

= 2.5x - 7x - 5 + 9.7

= -4.5x - 4.7

Therefore, the values will be 4.5x - 4.7.
