If g(x) = 3x - 1 and if g(a) = 7, then which of the following is the value of a?

So,

And,

But, given g(a) = 7

So, from 2nd and 3rd step,

3a-1=7

3a=6

Therefore, a = 2

8/3

Step-by-step explanation:

So if a=x then 3a-1=7 therefore 3a=8 and a=8/3

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.
