40 ! plz show step by step explanation. solve each question as an inequality. tony has three more than twice as many coins as peter. together they have fewer than 87 coins. how many coins does peter have? of 184 parking places, fewer than 70 were filled. how many places were not filled?

hope this helps

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.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
