Answer: 42/13

Step-by-step explanation: Multiply everything by 7 to eliminate the fraction:

k+ 21 - 14k = -21

Isolate the variable:

k - 14k = -21-21

13k= -42

divide the sides by -13.

Hallie bikes 1 5/8 km before lunch 6 1/4 km How much farther does hallies bike after lunch than before lunch? Express your answe

kondaur [170]

Distance biked before lunch = 1 $\frac{5}{8}$ km (the number is written in mixed fraction)

⇒ Distance biked before lunch = $\frac{13}{8}$

Distance biked after lunch = 6 $\frac{1}{4}$ km (the number is written in mixed fraction)

⇒ Distance biked after lunch = $\frac{25}{4}$

We need to determine how much farther does Hallie bike after lunch than before lunch

Extra distance biked after lunch vs. before lunch = $\frac{25}{4}$ - $\frac{13}{8}$

⇒ Extra distance biked after lunch vs. before lunch = $\frac{50-13}{8}$

⇒ Extra distance biked after lunch vs. before lunch = $\frac{37}{8}$

⇒ Extra distance biked after lunch vs. before lunch = 4 $\frac{5}{8}$ (in mixed fraction)

Hence, Hallie biked 4 $\frac{5}{8}$ km extra after lunch vs. before lunch.

the length of a rectangle is 3 times the width. The perimeter is 44 cm. What are the dimensions of the rectangle?

Gnom [1K]

Hello there
We can say that,
The length = 3u
The width= 1u
3u + 1u +3u +1u= 44cm
8u= 44cm
1u= 44cm / 8
= 5.5cm
Length= 5.5 cm x 3
=16.5 cm
Width= 5.5 cm

Hope this helps :))
