It's D on the real I just need to get this to 20 characters sooooooooooooo
Answer:
c=24
Step-by-step explanation:
Step 1: Add 7 to both sides.
1/3c−7+7=1+7
1/3c=8
Step 2: Multiply both sides by 3.
3*(1/3c)=(3)*(8)
c=24

Answer:
10) Exact Answer: 36
Estimate: 36
11) Exact Answer: 2001
Estimate: 1900
Step-by-step explanation:
10a) To find the exact answer, simply divide the given numbers.
10b) To find the estimated answer, use compatible numbers. We know that any "hundred" number is easily divisible by 5. Therefore, 900/5 = 36.
It is possible for the estimate to be the same as the exact answer.
10a) To find the exact answer, simply divide the given numbers.
10b) To find the estimated answer, use compatible numbers. There is no pattern we can look for, so round to the nearest whole number.
We know that if we rounded .38 to 0 or 1, the answer would not be nearly as close as if we rounded .38 to .4.
Therefore, 760/.4 = 1900

I thought about this for a while and then recognized that this number is possibly divisible by {3, 4, 6, 8, 9, 10, 12, etc.}
So I look for possible sets of 3 numbers here that add up to 18. The first such set I recognized was {4, 6, 8}. These digits do add up to 18. Unfortunately, 468 is not in the desired range (600,700).
Thus, I could try either {6, 4, 8} or {6, 8, 4}.
There may be other combinations of 3 numbers (which must add up to 18).
Test 684. Is 684 between 600 and 700, not including 600 or 700? YES.
Is the sum of {6, 4, 8} equal to 18? YES. So, 648 is one possible answer. Are there others?
Answer:
in the numerator
in the denominator
Step-by-step explanation:
First fraction simplifies to:
Dividing my a fraction is the same as multiplying by the reciprocal, so the second fraction simplifies to:
So the equation becomes:
The (x+3) and (x+5) terms cancel out, so what your left with is
Expanding this term you get the answer:
in the numerator
in the denominator
