Answer:

Length = 42 feet

Width = 21 feet

Step-by-step explanation:

Let the length and width be represented by L and W

L = 2W

Perimeter (P) = 126 feet

2(L + W) = 126

L + W = 126/2 = 63

2W + W = 63

3W = 63

W = 63/3 = 21 feet

L = 2W = 2 × 21 feet = 42 feet

explain why multiplying the numerator and denominator of a fraction by the same number results in an equivalent fraction
Tomtit [17]
Think:  You're treating the numerator and the denom. in precisely the same way.  In doing so you are NOT changing the value of the fraction, only the appearance.

Example:  start with 2/3.  Mult num. and den. both by 7:  14/21.

2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.

kendra knits hats. She starts with 3 3/4 yd of yarn. After knitting for 5 1/4 h their is 1 1/8 yd of yarn left. At what rate doe
nadezda [96]

Answer:

The rate is  1 ÷ 2 yards per hour

Step-by-step explanation:

The computation of the rate does the amount of yarn changes is given below:

= 3 3 ÷ 4 - 1 1 ÷8

= 15 ÷ 4 - 9 ÷ 8

= 21 ÷ 8 yards

 Now divide the above fraction by the number of hours

= 21 ÷ 8 yards ÷ 5 1 ÷ 4

= 21 ÷ 8 ×  4 ÷ 21

= 1 ÷ 2 yards per hour

Hence, the rate is  1 ÷ 2 yards per hour

The same would be relevant

What value of x makes the equation −2x−(−5−4x)=−5(2x−7) true?
Anestetic [448]

Answer:

-2x - (-5 - 4x) = -5(2x - 7)

-2x + 5 - 4x = -5 * 2x - 5 * (-7)  

-6x + 5 = -10x - 35

-6x + 5 + 10x = -10x - 35 + 10x

4x + 5 = -35

4x + 5 - 5 = -35 - 5

4x = -40

4x/4 = -40/4

x = 10
