65(7) = 455 sit-ups during a 7 day period
I would start off by taking away 1a. That would make the problem be 56ab3-35b.I only took away 1 because each have at least 1a and is okay to do.
Next I would deal with the variable b. I would cross of 1 b. That's because both sides have at least 1b. Now, it's shortened to be 56ab2-35.
Since you cannot take away anymore variables, you have to deal with 56 and 35. I start small with dividing each by 2. I am trying to see what the greatest number could be while making the numbers still be whole. That turns 56 into 28 when it's cut in half. The 35 now turns into 17.5.
I would assume your teacher would want the numbers to be whole. seeing as though when 35 is cut in half and makes a decimal number, I would leave them. What I mean by that is to leave the numbers as 56 and 35.
So, that means the answer is 56ab2-35.
I hope this helps!! (And makes sense)
Answer:
About 220 minutes.
What you have to do is divide 17 by 12 and multiply it by 155. After that, round the decimal up since the decimal part still counts as time.
It’s a straight line, and a straight line equals 180° so it would be:
180=6x+2x+12
180=8x+12
subtract 12 from both sides
168=8x
divide both sides by 8
21=x
the answer is 21 which is the second choice
Answer:
the answer is 19.3137
Step-by-step explanation:
each of the diagonal lines are 2.84 so multiply that times 4 because there are 4 of them then add the top and bottom lines which are 4 each so 8 plus the diagonal lines which are 11.3137 and you get 19.3137.
