Answer:
- equation: w +(2w -3) = 18/2
- length = 5 cm
- width = 4 cm
Step-by-step explanation:
Let w represent the width in cm. Then the length is 2w-3, 3 cm less than twice the width. The perimeter is twice the sum of these, so the sum of length and width is half the perimeter:
w + (2w -3) = 18/2
3w -3 = 9 . . . . collect terms
3w = 12 . . . . add 3
w = 4 . . . . divide by 3
2w-3 = 2·4 -3 = 5 . . . . length
The equation is w + (2w -3) = 18/2; the length is 5; the width is 4.
The answer would be 7/24
You can start by finding a common denominator. Since the lowest common denominator 3 and 8 have in common is 24 then that would be your denominator.
Then you can cross multiply 3*3= 9 and 2*8=16
16-9= 7
7/24
Then you are left with your answer:
is already in reduced terms.

y = 
x + 3
The equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange - 2x + 3y = 9 into this form
add 2x to both sides
3y = 2x + 9 ( divide all terms by 3 )
y = x + 3 ← in slope-intercept form
