Step-by-step explanation:
Tony has three more than twice as many coins as Peter. Together they have fewer than 87 coins. How many coins does Peter have?
Let t=tony and p=peter
so t=2p+3 but (t + p) is less than 87.
we can plug in our variables ((2p+3)+p)<87
Simplify (3p+3)<87
We can subtract three from both sides so we dont have to work around it.
take 84/3= 28
so assuming we could be at 87, the answer is p less than or equal to 28
Of 184 parking places, fewer than 70 were filled. How many places were not filled?
184, 70 filled
184-70= 114, minimum unfilled, maximum is all 184
so the inequality could be (let u be unfilled places) u is greaterthan or equal to 114.
the > or = and =or< are the smobols with a greater or less than with an underline.
