Answer:

Add 2 to each side

x=1/2

Step-by-step explanation:

(3√8x - 2 )= 4

Add 2 to each side

(3√8x - 2 +2= 4+2

3√8x = 6

Divide each side by 3

3/3√8x = 6/3

√8x = 2

Square each side

(√8x)^2 = 2^2

8x = 4

Divide each side by8

8x/8 = 4/8

x = 1/2

ziro4ka [17]

Answer : b. $65.10

1 appetizer: $7.39=7.39

2 entrees: $16.99 each= 2 * 16.99=33.98

1 dessert: $5.29= 5.29

2 drinks: $2.30 each=4.6

cost = 7.39 + 33.98 + 5.29 + 4.6 =$51.26

7% tax = 51.26 * 0.07 = 3.5882

20% gratuity = 51.26 * 0.2= 10.252

Total cost = 51.26 + 3.5882 + 10.252 =65.1002

the total amount = $65.1
