105 divided by 3 is 35:
3 goes into 1 zero times
3 goes into 10 3 times so you put the 3 onto of the 0 
when you subtract 9 from 10 (3x3) you get 1 and since 3 can't go into 1 you bring down the 5
3 goes into 15 5 times so you final answer is 35

Theodore needs to mix a 30% alcohol solution with a 50% alcohol solution to create 100 milliliters of a 32% solution. How many m
Goryan [66]

Answer:

50 % alcohol solution = 10 millimetres

30 % alcohol solution = 90 millimetres

Step-by-step explanation:

two equations can be derived from this question

x + y = 100 equation 1

0.3x + 0.5y = 100 x 0.32 = 32

0.3x + 0.5y = 32 equation 2

where :

x = 30% alcohol solution

y = 50% alcohol solution

multiply equation 1 by 0.3

0.3x + 0.3y = 30 equation 3

subtract equation 3 from 2

0.2y = 2

y = 10

substitute for y in equation 1

x + 10 = 100

x = 100 - 10

x = 90
