Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Bryan, Charlie and Adam have some stickers.
Adam has
710 as many as Bryan.
Charlie has 10 less stickers than Adam.
Let the number of stickers that Bryan has be 10 u.
- Number of stickers that Adam has = _____
- Number of stickers that Charlie has = _____
- Total number of stickers = _____
- Number of stickers that Bryan has more than Charlie = _____
(a)
Let the number of stickers that Bryan has = 10 u
Number of stickers that Adam has = 7 u
(b)
Number of stickers that Charlie has = 7 u - 10
(c)
Total number of stickers
= 10 u + 7 u + 7 u - 10
= 24 u - 10
(d)
Number of stickers that Bryan has more than Charlie
= 10 u - (7 u - 10)
= 10 u - 7 u + 10
= 3 u + 10
Answer(s): (a) 7 u; (b) 7 u - 10; (c) 24 u - 10; (d) 3 u + 10
