X+2 over 3 = 8/5 solve for x
Answers
Multiply each side by 3 :
(x+2) = 24/5
Remove the parentheses on the left side:
x + 2 = 24/5
Subtract 2 from each side: (Express '2' as '10/5')
x = 24/5 - 10/5 = 14/5 = 2.8
x=14/5
It is this because you would have to first multiply each side by 3, making the equation x+2=24/5, or 4 and 4/5.
Then you would have to subtract two from each side, making x=2 and 4/5, or 14/5

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 is midpoint in a line ?
A midpoint in a given line segment divides the line segment in two equal parts.
In the given question
AB is a line segment.
Point A has co-ordinates (-1,5) and midpoint M has co-ordinates (1,3).
Assuming point B has co-ordinates (x,y)
We know midpoint formula is give by
M of x = (x₁ + x₂)/2 and M of y = (y₁ + y₂)/2
∴ 1 = (-1 + x₂)/2
2 = - 1 +x₂
x₂ = 3
And
3 = ( 5 + y₂)/2
6 = 5 + y₂
y₂ = 1
So the co-ordinate points of B(x₂,y₂) = (3,1)

Answer:
(3,1)
Step-by-step explanation:
let B be (x,y)
m(1,3)=midpoint
A(-1,5)=(x1,y1)
B(x,y)=(x2,y2)
(1,3)= x1+x2/2 y1+y2/2
(1,3)= -1+x/2 5+y/2
so,
-1+x/2=1 5+y/2=3
-1+x=2 5+y=6
x=3 y=1
therefore the co ordinates of B(x,y) are (3,1)
