PLEASE HELP! Water = 946.36 g Sugar = 196.86 g Lemon Juice = 193.37 g Lemonade = 719.84 g Just Lemons Lemonade Recipe Equation: 2 water + sugar + lemon juice = 4 lemonade Mole conversion factors: 1 mole of water = 1 cup = 236.59 g 1 mole of sugar = 1 cup = 198 g 1 mole of lemon juice = 1 cup = 229.96 g 1 mole of lemonade = 1 cup = 225.285 g

Try to reduce the. amount of leftover ingredients by changing the amount of one, two, or all three starting ingredients. Show your stoichiometric calculations below.

linda: 3 ; laura: 15

step-by-step explanation:

note that linda + laura's age is 18, and that linda is 12 years younger than her sister.

let "linda" = x , "laura" = y:

x + y = 18

x = y - 12

first, plug in y - 12 for x in the first equation:

(y - 12) + y = 18

simplify.

2y - 12 = 18

isolate the variable (y). note the equal sign, what you do to one side, you do to the other. do the opposite of pemdas. first add, then divide.

2y - 12 (+12) = 18 (+12)

2y = 18 + 12

2y = 30

(2y)/2 = (30)/2

y = 30/2

y = 15

next, plug in 15 for y in the second equation (the other equation would work too).

x = y - 12

x = (15) - 12

x = 3

linda's age is 3, laura's age is 15.
