Answer:
Step-by-step explanation:
Yes, it's reasonable.
What you are doing is solving the question by rounding. You come up with an answer. Suppose you loose the decimal somewhere and you get 0.36? Is that reasonable? Do you just write the answer in the provided blank and move on. What now?
You get it wrong?!!
But your estimate should be about 9/3 = 3. Now you look at your calculator with great misgivings, because it made a mistake. Did it or did you? Well ultimately you did, but you have to blame something. So the calculator takes the heat.
Who knows? Maybe the decimal doesn't work. It's stuck or something. In any event you should be aware that there's no way the answer could be 0.36 when you estimate it to be 3.
Answer:
15/2
Step-by-step explanation:
You want to first find the connection between the first statement, y=10 and x=20. The connection is that Y is X divided by 2. Then you want to just do the same equation to the y and keep it a fraction. (Hint. a fraction is the same as what you do to divide, its just the equation before you find your answer.) so your answer is 15/2.
Hope its right, and i hope this helped.
16 rods can be made.
common denominators. 4/5=16/20.
16/20 divided by 1/20 is 16. 16 rods
Answer:
Step-by-step explanation:
(-12+50)/(-2-3)+72/(4+2)
simplify: 38/67/6
multiply by the reciprocal: 38/67*6/1
you get: 228/67
decimal: 3.402985075
