One month, jill worked 2 more hours than ivan, and susie worked three times as many hours as jill. together they works 48 hours. find the number of hours each person worked

Let us assume Ivan worked = x hours.

Jill worked 2 more hours than Ivan.

Therefore, jill worked = x +2 hours.

Susie worked three times as many hours as Jill.

Therefore, Susie woked 3 times of number of hours of Jill = 3(x+2).

Total number of hours they worked together = 48 hours.

Number of hours Ivan worked +  Number of hours Jill worked + Number of hours Susie worked = 48.

Therefore,

x+ x+2 + 3(x+2) =48.

Distributing 3 over (x+2), we get 3x +6.

Therefore,

x+ x+2 + 3(x+2) =48  

=> x+x+2+3x+2 = 48.

Combining like terms, we get

5x + 4 = 48.

Subtracting 4 from both sides, we get

5x + 4-4 = 48-4.

5x = 44.

Dividing both sides by 5, we get

x= 44/5 hours or 8 4/5 hours.

Therefore, Ivan worked = 8 4/5 hours.

Jill worked = x +2 hours = 8 4/5 hours + 3  = 11 4/5 hours.

Susie woked = 3 (x+2) = 3 (44/5 +2 ) = 3(54/5) = 162/5 hours or 32 2/5 hours.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

might be the correct answer will be question number 2
