Upper N subscript 2 (g) plus 3 upper O subscript 2 (g) plus 2 upper O subscript 3 (g) plus 2 upper O (g) right arrow 8 upper N upper O (g) plus 4 upper N upper 0 subscript 2 (g) plus 2 upper O subscript 3 (g). Upper N subscript 2 (g) plus 3 upper O subscript 2 (g) plus upper O subscript 3 (g) plus upper O (g) right arrow 9 upper N upper O (g) plus 3 upper N upper 0 subscript 2 (g) plus 2 upper O subscript 3 (g). Upper N subscript 2 (g) plus 3 upper O subscript 2 (g) right arrow 3 upper N upper O subscript 2 (g). Upper N subscript 2 (g) plus 2 upper O subscript 2 (g) right arrow 2 upper N upper O subscript 2 (g).

answer: 177/8

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

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
