Answer:
x=16
Step-by-step explanation:
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.
It would still be 11.5% no matter how you put or state it
Step-by-step explanation: Let x be the larger number and let y be the smaller one.
x-y=13
x=2y+3
Now you can substitute x=2y-3 into the first equation.
x-y=13=(2y+3)-y
y+3=13
y=10
x=2y+3=20+3=23. Hope that helped!
