Four less than the quotient of a number and 4 is 14. What is the number? Let n be the unknown number.
Maru [420]
So the equation is n/4-4=14
then you +4 to both sides 
n/4-4=14 so now the equation is n/4=18 then you multiply 18 by 4 and get 72
   +4    +4
then to check your work
72/4-4=14
so N=72

Ivan finished Four-fifths of his math homework problems and all 3 problems for his science homework before dinner. If he finishe
valentinak56 [21]

Answer:

Step-by-step explanation:

Since we know that Ivan finished all his science problems (3) we know that there are only math problems remaining

substract the science problems from the total 43-3=40

And now we can determine the amount of math problems

4/5 = 40/x where x is the total amount of math problems Ivan was assigned

cross multiply

4x = 5*40

4x=200

isolate the variable

4x/4 = 200/4

x=50

So Ivan was assigned a total of 50 math problems

(Note*) since there are 40 math problems finished 40/50 is equal to 4/5. Just a tip if you don't want to do the whole calculation

Hope this helps!
