Using each of the digits 0-6 only once, make two equivalent ratios (also known as a proportion).

Step-by-step explanation:

-The digits between 0-6 are:

#We form the first ratio:

#Multiplying both the denominator and numerator in the first ratio gives an equivalent ratio whose digits lie between 0-6:

Simplifying the second ratio gives you the first ratio.

Hence, the two equivalent ratios are:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
