Answer:
r = 7
Step-by-step explanation:
Use the distributive property by multipling the -8 to the 2r and the -8, do the same thing on the other side with the -3.
Afterwards, combine like terms by adding 64 and 6.
Next, add 3r to the left side, I usually choose the number with the variable (the letter) that looks like it will be easier to subtract. This leaves only 21 on the right side.
Next subtract 70 from both sides
Divide -13 by both sides
You should get the answer of r=7

Answer: $7,018,000</h3>
This value is a little over 7 million dollars
======================================================
Explanation:
120,587 rounds to 121,000 when rounding to the nearest thousand.
The instructions don't mention rounding 58, so we'll leave it as that
Multiply the values to get
58*121,000 = 7,018,000
which is the estimate of how much money was earned.
-----------
The actual amount of money earned is
58*120,587 = 6,994,046
which isn't too far off of our estimate.
-----------
Note: the value of 25 days is never used. You could have any other number of days you want, and the answer is still the same. This value is probably either filler or some kind of distraction.
Answer:
5.34 x 10^-2
Step-by-step explanation:
If the term in the middle is 16x^2
6x^2-24x-16x^2-9x+1 =
-10x^2-33x+1
In the circumference formula given d is the diameter which is 2 times r ( r is the radius)
R is given as 6 feet, diameter = 2 x 6 = 12 feet.
Circumference = 12 feet x 3.14 = 37.68 feet
