(1/4x)^-2=a0/x2 What ia the answer?

Hi, sorry your question is not clear enough but from my own method of solving the question,

x=4

Step-by-step explanation:

so,I'm assuming the question is set this way:

we know that zero divided by any number is still 0.

so automatically, 'a' would be raised to the power of 0

then,

so

cross multiplying we have :

which is equal to:

x=4

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.
