Fill in the blanks.
For (a) to (d), give the answers in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
12 of Bryan's stickers is 2 less than
17 of Adam's stickers.
Let
12 of Bryan's stickers be 1 u.
- Number of stickers that Bryan has = _____
- Number of stickers that Adam has = _____
- Total number of stickers = _____
- Difference in the number of stickers between Adam and Bryan = _____
(a)
12 of Bryan's stickers = 1 u
22 of Bryan's stickers = 2 u
(b)
17 of Adam's stickers =
12 of Bryan's stickers + 2
17 of Adam's stickers = 1 u + 2
77 of Adam's stickers = 7(1 u + 2) = 7 u + 14
(c)
Total number of stickers
= 2 u + 7 u + 14
= 9 u + 14
(d)
Difference in the number of stickers between Adam and Bryan
= 7 u + 14 - 2 u
= 7 u - 2 u + 14
= 5 u + 14
Answer(s): (a) 2 u; (b) 7 u + 14; (c) 9 u + 14; (d) 5 u + 14
