The value is 1.1. Because it is 1.1 spaces away. the negative symbol isn’t,t important in this case.

Hello, there!

I think you mean the absolute value of -1.1

This would be 1.1 as absolute value is how many units away from 0 a number is.

Even if you were asking the absolute value of 1.1, the answer would be still be 1.1

Absolute value is always positive, regardless of the number.

I hope I helped!

Let me know if you need anything else!

The length of a rectangle is 5ft longer than twice the width if the perimeter is 58 ft find the length and width of the rectangl

Travka [436]

----------------------------------
Define x :
----------------------------------
Let the width be x.
Width = x
Length = 2x + 5 // Length is 5ft longer than twice the width

----------------------------------
Formula for Perimeter :
----------------------------------
Perimeter = 2 (Length + Width)

----------------------------------
Find Width :
----------------------------------
58 = 2 ( 2x + 5 + x) // Substitute Length and Width into formula
58 = 2 (3x + 5) // Combine like terms
58 = 6x + 10 // Apply distributive property
48 = 6x // Take away 10 from both sides
6x = 48 // Switch sides. Make x the subject
x = 8 // Divide by 6 on both sides

----------------------------------
Find Length and Width :
----------------------------------
Width = x = 8 ft
Length = 2x + 5 = 2(8) + 5 = 21 ft

--------------------------------------------------------------------
Answer: The length is 21 ft and the width is 8 ft.

ipn [44]

Answer:

x = -4, v = 2.5

x = -14, v = -2.5

Step-by-step explanation:

I am a bit confused with the beginning part of the question. From what I understand, you are trying to solve for x and then plug x into the top equation to find the value for V. I am sorry if that is not what you are looking for. If it is, look below!

x + 9 = 5

x = 5 -9

x = -4

v(x + 9)2 = 25

v(-4 + 9)2 = 25

v(5)2 = 25

v(10) = 25

v = 25/10

v = 2.5

x + 9 = -5

x = -5 -9

x = -14

v(x + 9)2 = 25

v(-14 + 9)2 = 25

v(-5)2 = 25

v(-10) = 25

v = 25/(-10)

v = -2.5

I hope this helped! If not, I am sorry. :(

Answer:

c + (a + 1.70) = 6.70

Step-by-step explanation:

you start the equation by Subtracting how much more alan has to the total

(this will only be set as an equation do not actually solve it)

then add 1.70 to a

6.70 - 1.70 = a + c

(1.70 + a)

c + (a + 1.70) = 6.70 "
