A Multiply: (-4)12 =
B Multiply: (-5)(-10) =
C Multiply: (-17)(0)=

A . -48

B . 50

C .  0

Step-by-step explanation:

We are asked to multiply three different problems, so, let us look at A.

(-4)12 = -48

How?

Well, simple, you have to multiply 12 by 4 which is 48. Now since there is a negative, a positive multiplied by a negative always is a negative. 48 becomes -48.

Now B. :

(-5)(-10) = 50

How?

Well, do normal multiplication at first, 5 by 10 which is 50. Now, there are two negatives , so, a negative times another negative is always positive. So 50 stays as 50.

Now C . :

(-17)(0) = 0

How?

Well, any number multiplied by zero is zero. Therefore, your answer is zero

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.
