Rita is going to make some cheeseburgers for a party. she buys some packets of cheese slices and some boxes of burgers. there are 20 cheese slices in each packet. there are 12 burgers in each box. rita buys exactly the same number of cheese slices and burgers. (i) how many packets of cheese slices and how many boxes of burgers does she buy?

answer: 20

step-by-step explanation:

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
