Answer:

1577.8 US dollars are received for 1127 UK pounds.

5669.5 UK pounds are received for US$7937.3.

Step-by-step explanation:

The questions are solved by proportions, using a rule of three.

How many US dollars are received for 1127 UK pounds?

1 UK pound = 1.4 US dollars

1127 UK pounds - x US dollars

Applying cross multiplication:

$x = 1127*1.4 = 1577.8$

1577.8 US dollars are received for 1127 UK pounds.

How many UK pounds are received for US$7937.3?

1 UK pound = 1.4 US dollars

x UK pounds - 7937.3 US dollars

$1.4x = 7937.3$

$x = \frac{7937.3}{1.4}$

$x = 5669.5
$

One month,Jill worked 2 more hours than Ivan,and Susie worked three times as many hours as Jill. Together they works 48 hours. F

vovikov84 [41]

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.
