For every 2 reeses pieces, there are 7 snickers. If there are 16 reeses pieces, how many total pieces of candy are there?

There are 72 pieces of candy.

Step-by-step explanation:

Since there are 16 Reeses in all, we need to find out how many 2's can fit in 16. We can do that by either multiplying or dividing.

16 ÷ 2 = 8 or 8 × 2 = 16

So we have 8 groups of 2 Reeses, now we need to multiply the groups of Reeses by how many Snickers.

So:

8 × 7 = 56

Now we need to add the Snickers and the Reeses.

56 + 16 = 72

72 candies

Step-by-step explanation:

To find the number of snickers, divide the 16 reese's pieces by two to get 8. For every two reese's pieces, there are seven snickers, so multiply that by seven to get 56. There are 56 snickers. Add the 56 snickers to the given 16 reese's pieces for 72 total pieces of candy. Hope this helped ^^

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
