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.
15 of Bryan's stickers is 7 less than
110 of Adam's stickers.
Let
15 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)
15 of Bryan's stickers = 1 u
55 of Bryan's stickers = 5 u
(b)
110 of Adam's stickers =
15 of Bryan's stickers + 7
110 of Adam's stickers = 1 u + 7
1010 of Adam's stickers = 10(1 u + 7) = 10 u + 70
(c)
Total number of stickers
= 5 u + 10 u + 70
= 15 u + 70
(d)
Difference in the number of stickers between Adam and Bryan
= 10 u + 70 - 5 u
= 10 u - 5 u + 70
= 5 u + 70
Answer(s): (a) 5 u; (b) 10 u + 70; (c) 15 u + 70; (d) 5 u + 70
