Answer:
x=5
Step-by-step explanation:
3.5=0.75x-0.25
add 0.25 to 3.5
3.75=0.75x
divide 3.75 by 0.75
x=5
If you did the math it is obvious that the answer is 20%
The minimum function determines the lowest number in a range!
% means 'parts out of 100' so
25%=25/100
is 12 is 25 parts out of 100 of a number
so 12=(25/100)x
25/100 simplifies to 1/4
or if 12=(1/4)x
we multiply both sides by 4 and get
48=1x
A baby gets 1 ml of vitamins every day. If you would like to know how many weeks will a 50 ml bottle last, you can calculate this using the following steps:
50 ml / 1 ml = 50 days
50 days / 7 days = 50 / 7 = 7.14 weeks
Result: A 50 ml bottle will last for about 7 weeks.
