Farida bought 20 stamps consisting of 20 sen stamps and 60 sen stamps. The total cost of the stamps is RM8.80. How many 20 sej s
krek1111 [17]

Answer:

# of 20cent stamps = 8

Step-by-step explanation:

Let the  number 20cent stamps be = x

Let the number 60 cents stamps be = y

Total number of stamps => 20 = x + y ----------- ( 1 )

Total cost of the stamps = 8.80

That is, 0.20x + 0.60y = 8.80 ------------- ( 2 )

      ( 2 ) => 20x + 60y = 880

            => x + 3y = 44

           =>  x = 44 - 3y

Substitute x in  ( 1 ) => x  +  y = 20

                                 44 - 3y + y = 20

                                     - 2y = 20 - 44

                                     - 2y = - 24

                                       2y = 24

                                       y = 12

Substitute y = 12 in  ( 1 ) => x + y = 20

                                         x + 12 = 20

                                            x = 8

A cleaning crew can clean 5 offices in 6 hours how many offices can they clean in 12 hours
weeeeeb [17]
1 cleaning crew = 5 offices in 6 hours
You want to find out the number of offices they can clean in 12 hours
6 (hours) is \frac{1}{2} of 12 (hours)
The opposite of \frac{1}{2} is 2
6 (hours) multiplied by 2 (opposite of \frac{1}{2} ) is equal to
12
6 x 2 = 12, 12 = the number of offices you're trying to find.
Therefore, you need to multiple 5 by 2 (number that is double), so
5 x 2 = 10
The crew can clean 10 offices in 12 hours
