Length (L): 4w - 5
width (w): w
Perimeter (P) = 2L + 2w
140 = 2(4w - 5) + 2(w)
140 = 8w - 10 + 2w
140 = 10w - 10
150 = 10w
15 = w
Length (L): 4w - 5 = 4(15) - 5 = 60 - 5 = 55
Answer: width= 15meters, length=55 meters

Step-by-step explanation:
Answer:
- 9 students : 1 table
- 87 pebbles per aquarium
- 10 slices for each child
Step-by-step explanation:
A "unit" rate is one that has a denominator of 1 unit.
12 apples : 3 baskets has a denominator of 3, so is not a unit rate. It could be made into a unit rate of 4 apples : 1 basket by dividing the numbers by 3.
Similarly, $5 for 4 muffins has a denominator of 4, so is not a unit rate. The equivalent unit rate is ($5/4) per muffin, or $1.25 per muffin.
All of the other offered choices are unit rates. (See list above.)
I think it would be y plus 3 times 2 equals 5x. I'm not sure if that is what they are asking for.
