Answer:

7\times (-3) \times  (-2)^2=-21\times 4=-84

Step-by-step explanation:

Multiplication :

Multiplication means to add equal groups or we can say multiplication is repeated addition . We use symbol × to denote multiplication .

Consider a bag containing 5 balls then 7 bags will contain 5+5+5+5+5+5+5=7+7+7+7+7=35 balls or we can directy say that 5 bags will contain 5×7 = 35 balls .

If we are saying 6 times 8, it means 8+8+8+8+8+8 = 6+6+6+6+6+6+6+6 .

i.e 8 is added 6 times or 6 is added 8 times .

In problem 7×9 = 63 , 7 and 9 are factors and 63 is the product .

To find : 7\times (-3) \times  (-2)^2

Solving 7\times (-3) :

7\times (-3)=(-3) +(-3)+(-3)+(-3)+(-3)+(-3)+(-3)=-21

Solving (-2)^2 :

(-2)^2=(-2)\times (-2)=4

Therefore ,

7\times (-3) \times  (-2)^2=-21\times 4=-84

The table below shows the numbers of tickets sold at a movie theater on Friday.
prisoha [69]

Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday  

= Sum of ( Adult + Children's ) tickets  = 1,678  + 976 = 2,654 ....  (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold =   2 times  the number of adult tickets sold on Friday  

                             =  1,678 x 2  = 3,356

Children's Tickets sold = 3 x the number of children's tickets sold on Friday.

                                        =  976  x 3 = 2, 928

So, the total number of tickets sold on Saturday  

= Sum of ( Adult + Children's ) tickets  = 3,356 + 2,928 = 6, 284 ....  (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 +  6, 284  =   8,938

Hence, total number of tickets sold over these two days is 8,938.
