Answer:

1- Let x = original price  then

x - .20x = 48

x(1 - .20) = 48

x(.80) = 48

x = 48/.80

x = $60

2-Let "x" be the number of lessons.

240 - 15x = 0

240 = 15x  

x = 16 lessons

3-divide equation by 2:

(2W-4) + W = 32

2W - 4 + W = 32

2W + W = 32 + 4

3W = 36

W = 36/3

W = 12 cm

Find the Length using L = 2W-4:

L = 2(12) - 4

L = 20 cm

Check: 2(20) + 2(12) = 64

4-P stands for the original price. The 90 stands for 90 %. Wendy paid 100-10, or 90 %.

The function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an air
tensa zangetsu [6.8K]

The total time taken for round trip will be: (f+g)(x) = 14x+11

Step-by-step explanation:

Given

f(x) = 4x+13\\g(x) = 10x-2

In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.

(f+g)(x) = f(x)+g(x)\\= (4x+13)+(10x-2)\\=4x+13+10x-2\\=4x+10x+13-2\\=14x+11

Hence,

The total time taken for round trip will be: (f+g)(x) = 14x+11
