Paul has 2/3 as many postcards as Shawn. The number of postcards Shawn has is 3/5 of the number of postcards Tim has. If the thr
Otrada [13]

Tim has 84 more postcards than Paul.

Step-by-step explanation:

Given,

Total number of postcards = 280

Let,

Tim's share of postcards = x

Shawn's share of postcards = \frac{3}{5}\ of\ Tim's\ share = \frac{3}{5}x

Paul's share of postcards = \frac{2}{3}\ of\ Shawn's=\frac{2}{3}(\frac{3}{5}x)=\frac{2}{5}x

According to given statement;

x+\frac{3}{5}x+\frac{2}{5}x=280

Taking LCM

\frac{5x+3x+2x}{5}=280\\\\\frac{10x}{5}=280\\\\2x=280

Dividing both sides by 2

\frac{2x}{2}=\frac{280}{2}\\x=140

Paul's share = \frac{2}{5}x=\frac{2}{5}(28)=56

Difference = Tim's share - Paul's share

Difference = 140 - 56 = 84 cards

Tim has 84 more postcards than Paul.

RideAnS [48]

Answer:

g(f(2)) = 41

b)41

Step-by-step explanation:

g(f(2)) = 41

f(2)= 2(2²) + 5 = 13

So g(f(2)) → g(n = 13)

g(n = 13)→ 3(13) + 2 = 41
