Brian had 42 class fair tickets to sell. he sold 5/6 of the tickets . how many tickets did brian sell?

 Brian sold 35 tickets.

Step-by-step explanation:  Given that Brian had 42 class fair tickets to sell and he sold of the tickets.

We are to find the number of tickets that Brian sold.

We have

Total number of tickets that Brian had = 42.

Since he sold five-sixth of the total tickets that he had, so the number of tickets that Brian sold is given by

Thus, Brian sold 35 tickets.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

i think it would be 42cm
