Drag and drop numbers into the boxes to complete and solve the equation for the situation. One month, Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby.
Together they worked 102 hours. Find the number of hours each person worked.

Isaac worked 12 hours

Ruby worked 18 hours

Svetlana worked 72 hours

Step-by-step explanation:

Here in this question, we are interested in knowing the number of hours each person worked.

We proceed as follows;

Let the number of hours Isaac worked be x hours.

From the question, we are told that Ruby worked 6 hours more than Isaac

So the number of hours Ruby worked will be;

(x + 6) hours

Also;

Svetlana worked 4 times as many as Ruby:

This means that we have to multiply the number of hours Ruby worked by 4 to get the number of hours that Svetlana worked;

So the number of hours Svetlana worked will be : 4(x + 6) hours

Since the three worked a total of 102 hours, to get the number of hours each worked, we need to add together the number of hours each individual put in to work and equate to 102;

Mathematically, that would be;

x + x + 6 + 4(x + 6) = 102

2x + 6 + 4x + 24 = 102

6x + 30 = 102

6x = 102-30

6x = 72

x = 72/6

x = 12 hours

So Isaac worked x hours = 12 hours

Ruby worked (x + 6) hours = 12 + 6 = 18 hours

Svetlana worked 4(x + 6) hours = 4(18) = 72 hours

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
