which equation has no solution?
a. 9x + 9 = 11x – 2x + 9
b. 7x + 30 = x + 6(x + 5)
c. -5x + 9 = 2x + 9 - 7x
d. 7x - 6 = x + 6(x + 5)

D. 7x - 6 = x + 6(x + 5)

Step-by-step explanation:

a equation will have no solution if the final value is not real or not equal

D) 7x - 6 = x + 6(x + 5)

7x-6 = x+6x+30

7x-x-6x-6-30= 0

-36≠0

so -36 ≠ 0 ... so no solution

A. 9x + 9 = 11x – 2x + 9

 9x-11x+2x+9-9=0

  0=0    

have solution, Real, true

B. 7x + 30 = x + 6(x + 5)

7x+30 = x+6x+30

7x-x-6x+30-30= 0

0=0

have solution, Real, true

C. -5x + 9 = 2x + 9 - 7x

-5x-2x+7x+9-9= 0

-7x+7x=0

0=0

have solution, Real, true

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.
