Write the following equation in standard form then solve. 6q^2-2q=5q^2-5q+28

q = -7, q = 4

Step-by-step explanation:

subtract 5q² - 5q + 28 from both sides to obtain standard form

q² + 3q - 28 = 0 ← in standard form

(q + 7)(q - 4) = 0 ← in factored form

equate each factor to zero and solve for q

q + 7 = 0 ⇒ q = - 7

q - 4 = 0 ⇒ q = 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.
