Horatio is solving the equation Negative three-fourths + two-fifths x = StartFraction 7 Over 20 EndFraction x minus one-half. Which equations represent possible ways to begin solving for x? Check all that apply. Two-fifths x = StartFraction 7 Over 20 EndFraction x + one-fourth
Two-fifths x = StartFraction 7 Over 20 EndFraction x + five-fourths
Negative three-fourths = negative StartFraction 1 Over 20 EndFraction x minus one-half
Negative three-fourths = three-fourths x minus one-half
Negative three-fourths + StartFraction 1 Over 20 EndFraction x = negative one-half

the one below it is a function

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

a reflection across the x axis and a 90 degree rotation left and right.
