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.
16 of Bryan's stickers is 2 less than
19 of Adam's stickers.
Let
16 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)
16 of Bryan's stickers = 1 u
66 of Bryan's stickers = 6 u
(b)
19 of Adam's stickers =
16 of Bryan's stickers + 2
19 of Adam's stickers = 1 u + 2
99 of Adam's stickers = 9(1 u + 2) = 9 u + 18
(c)
Total number of stickers
= 6 u + 9 u + 18
= 15 u + 18
(d)
Difference in the number of stickers between Adam and Bryan
= 9 u + 18 - 6 u
= 9 u - 6 u + 18
= 3 u + 18
Answer(s): (a) 6 u; (b) 9 u + 18; (c) 15 u + 18; (d) 3 u + 18
