Steven has a rectangular rug with a perimeter of 18 feet The width of the rug is 6 feet what is the length of the rug
zheka24 [161]

Answer:

Length = 3 ft

Step-by-step explanation:

If the equation for perimeter is p = 2 (L+W)

You can plug in the information you already have

1) 18 = 2 (L+6)

2) Simplify by first dividing 2 by itself to cancel it out and then by 18 which would equal 9 leaving you with the equation 9 = L+6

3) Now to leave the L alone on the right you need to cancel out the 6 by subtracting 6 from itself and then from 9 which would leave you with the equation and the answer to the problem, 3 = L

Rose walks 2 2/3 km in three-fifths of an hour. If her speed remains unchanged, how many kilometres can she walk in one and thre
Artyom0805 [142]

Answer:

Distance = 7 7/9 Km

Step-by-step explanation:

Given the following data;

Distance = 2⅔ = 8/3 Km

Time = ⅗ hour

First of all, we would find her speed;

Speed = distance/time

Speed = (8/3)/(3/5)

Speed = 8/3 * 5/3

Speed = 40/9 km/h

Next, we would find the distance covered when time = 1¾ hours

Distance = speed * time

Distance = 40/9 * 1¾

Distance = 40/9 * 7/4

Distance = 10/9 * 7

Distance = 70/9

Distance = 7 7/9 Km

When I triple my number and add ten, I get my number plus `36.` What is my number?
Mice21 [21]

Based on the information given, the number is 13

<h3>How to determine the number</h3>

From the information given;

Let the number be x

We have that;

3(my number) + 10 = my number + 36

Substitute the number as x, we have;

3x + 10 = x + 36

collect like terms

3x - x = 36 - 10

2x = 26

Make 'x' the subject of formula

x = 26/ 2

x = 13

The number is 13

Thus, based on the information given, the number is 13
