The length of a room is 5 more than twice its width. If the total perimeter is 40 meters, what is the width of the room? Simplify the following expression:

Answers

Answer 1

Answer:

Answer:

width = 5 m

Step-by-step explanation:

let the width of the room be w then the length = 2w + 5 ( that is 5 more than twice its width )

perimeter is the sum of the sides

for a rectangular room the perimeter is calculated as

perimeter = 2 ( length + width ) = 2(2w + 5 + w) = 2(3w + 5)

given the perimeter is 40 m , then equating

2(3w + 5) = 40 ( divide both sides by 2 )

3w + 5 = 20 ( subtract 5 from both sides )

3w = 15 ( divide both sides by 3 )

w = 5

that is the width of the room is 5 m

What’s the distance between (1, 7) and (-2, -4) please help

Answers

Answer:

the slope is 11/3

so distance is 130 or 11.4 in decimal form

Answer:

Exact distance = $√(130)$

Approximate distance = 11.40175

Explanation:

We'll use the distance formula

$d = √((x_1-x_2)^2+(y_1-y_2)^2)\n\nd = √((1-(-2))^2+(7-(-4))^2)\n\nd = √((1+2)^2+(7+4)^2)\n\nd = √((3)^2+(11)^2)\n\nd = √(9+121)\n\nd = √(130) \ \ \text{ ... exact distance}\n\nd \approx 11.40175 \ \ \text{ ... approximate distance}\n\n$

Answer:

A. 25%

25% is equivalent to 1/4 and when you multiply 75 by 4 you get 300. Which means 75 is equivalent to 1/4 and 1/4 is equivalent to 25%. So the answer is 25%. I'm so sorry if this explanation is bad
