Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. he has a 10% alcohol solution and a 15% alcohol solution. which equation can bruce use to determine how much of the 10% alcohol solution he should use? 0.10x + 0.15(50 – x) = 50 + 0.12 0.10x + 0.15(50 – x) = 0.12(50) 0.10x + 0.15(50 – x) = 50 + 0.12 + 0.12(50)(0.10x)(0.15)(50 – x) = 0.12(50)

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
