5/2 = 8/x
5x = 16
x = 16/5
x = 3.2 or 3 1/5 fish
As a mixed number, -93.74 would be -93 74/100 or -93 37/50
Perimeter is the sum of all a shapes sides.
with that in mind, we know a rectangle has four sides. with 2 pairs being the same.
The length as told is, 5 centimeters less than two times the width. Two times the width would be 2w and five less than that would be minus five. so the length is 2w - 5
now to find the perimeter we do two times the width + two times the length.
2w + 2(2w -5) = 80.
Distribute: 2w + 4w - 10 = 80
Add ten to both sides and combine the 2w & 4w:
6w = 90
Divide both sides by 6: w = 15.
with this we know the width is 15. to find length plug in 15 to the 2w - 5 equation.
2(15) - 5 = 30 - 5 = 25.
Slap on the units and width = 15 cm, length = 25 cm
Answer:
1/2
Step-by-step explanation:
as x increases by 8, y increases by 4, simplify and you get as x increases by 2, y increases by 1
