For Erin, the graph shows 10 pounds of sugar are used for every 30 cups of tea.
For Lucia, we can let x=3 and we find 3 pounds of sugar are used for 10·3 = 30 cups of tea.
For the same number of cups of tea (30), Erin uses 10 pounds of sugar and Lucia uses 3 pounds of sugar.
Erin uses sugar at a higher rate.
Answer:
3
Step-by-step explanation:
7 -4 = 3
R = Rate of gasoline by automobile = 35 mi/gal
it is given that , 1 kilometer = 0.6214 miles
and 1 gallon = 3.78 liter
so
R = 35 (miles/gallon) (1 kilometer/0.6214 miles) (1 gallon/3.78 liter)
R = (35) (1/0.6214) (1/3.78) (miles x 1 kilometer/1 miles) (1 gallon/(1 gallon x 1 liter))
R = 14.9 kilometer/liter
So you need one plant and one fish
there are 24 fish and 18 plants, you need one for one
18 plants and 18 fish
