Question

This equation shows how the total length Elena has knit depends on the number of nights she has spent knitting: t = 10. The variable "n" represents the number of nights Elena has spent knitting, and the variable "t" represents the total length she has knit in centimeters. How many nights will Elena have to spend knitting in order to knit a total of 10 centimeters of scarf?

a) 1 night
b) 5 nights
c) 10 nights
d) 50 nights

Answer 1

Elena will need to spend 1 night knitting to create a 10 centimeters long scarf, based on the given equation t = 10n. The correct answer is (a) 1 night.

Step-by-step explanation:

The equation given is t = 10n, where t represents the total length Elena has knit in centimeters, and n represents the number of nights Elena has spent knitting. To find out how many nights Elena will have to spend knitting to achieve a total length of 10 centimeters, we need to solve for n when t equals 10 cm.

We can rearrange the equation to solve for n:

1. Set the equation equal to the desired total length: 10 = 10n.
2. Divide both sides of the equation by 10 to solve for n: n = 10 / 10.
3. Calculate the result: n = 1.

Therefore, Elena will have to spend 1 night knitting to create a scarf that is 10 centimeters in length. The correct answer is (a) 1 night.
