Solve 3- x/2>_15
A. XS-24
B. X2-24
C. X2-6
D. XS 6

x ≥ -24

Step-by-step explanation:

I think the equation is supposed to be written as an inequality.

3 - x/2 ≥ 15

Step 1: Subtraction property of equality

-x/2 ≥ 12

Step 2: Multiplication property of equality

-x ≥ 24

Step 3: Multiplication property of equality

x ≥ -24

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.
