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.
14 of Bryan's stickers is 11 less than
15 of Adam's stickers.
Let
14 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)
14 of Bryan's stickers = 1 u
44 of Bryan's stickers = 4 u
(b)
15 of Adam's stickers =
14 of Bryan's stickers + 11
15 of Adam's stickers = 1 u + 11
55 of Adam's stickers = 5(1 u + 11) = 5 u + 55
(c)
Total number of stickers
= 4 u + 5 u + 55
= 9 u + 55
(d)
Difference in the number of stickers between Adam and Bryan
= 5 u + 55 - 4 u
= 5 u - 4 u + 55
= 1 u + 55
Answer(s): (a) 4 u; (b) 5 u + 55; (c) 9 u + 55; (d) 1 u + 55
