2. which of these are solutions to the equation 2x3 = 54?

a. x= 3108

b. x= - 108

d. x= -3

c. x=3

x = 3

Step-by-step explanation:

as we know that

2x^3 = 54

x^3 = 54/2

x^3 = 27

taking cube root on both sides

x = 3

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
