You can set up an equation based off of the information given:

x represents the unknown number

3/5x - 1 = 23

add 1 to both sides to isolate the 3/5x

3/5x = 24

divide both sides by 3/5 to solve for x

x = 120/3

120/3 can be simplified into 40

Final answer: x = 40

Answer:

You will pay $4.31

Step-by-step explanation:

I know this because a fourth of $5.75 is 1.4375 so you would  round it to $1.44 and then $5.75 - $1.44 is $4.31.

So you will pay $4.31 for one milkshake.

D

using the double - angle identity

cos (2A) = cos² A - sin² A = 2cos² A - 1 = 1 - 2sin² A

the right side = 1 - 2sin² (112.5° ) with A = 22.5°

hence 2A = 2 × 22.5° = 45°

thus cos 45° = 1 - 2sin² ( 22.5°)
