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.
19 of Bryan's stickers is 2 less than
110 of Adam's stickers.
Let
19 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)
19 of Bryan's stickers = 1 u
99 of Bryan's stickers = 9 u
(b)
110 of Adam's stickers =
19 of Bryan's stickers + 2
110 of Adam's stickers = 1 u + 2
1010 of Adam's stickers = 10(1 u + 2) = 10 u + 20
(c)
Total number of stickers
= 9 u + 10 u + 20
= 19 u + 20
(d)
Difference in the number of stickers between Adam and Bryan
= 10 u + 20 - 9 u
= 10 u - 9 u + 20
= 1 u + 20
Answer(s): (a) 9 u; (b) 10 u + 20; (c) 19 u + 20; (d) 1 u + 20
