Answer:
-1
Step-by-step explanation:
If the first question mark is 3 then the next is 13 than the next still 13 and the right one 26 and then lastly x is equally to 2
Or
3x+9+10x=33
13x+9=33
13x=26
X=2
Answer:
The answer is <u>C.</u> 0.08x + $156.00 = r.
Step-by-step explanation:
Given:
Oprah makes $156.00 per day plus an additional 8% commission on her sales.
She sold x dollars worth.
Now, to find equation how much Oprah made in one day, r.
As. given in question:
She makes per day = $156.00.
Worth of sold = 
Commision on her sales = 8%.
And one day = 
Now, to get the equation Oprah made in one day:






<em>Thus, the equation is</em> 
Therefore, the answer is C. 0.08x + $156.00 = r.
16.5 degrees below the starting temp, whatever that is. If its 0, then -16.5 degrees.
The first equation would be (.5)5-11=-8.5, because the metal has been cooling for 5 hours.
The device that 'aids' in the cooling would be -5-3=-8, because it is a separate variable that cools the metal, so the amount the device cools is independent of the natural cooling amount, and the equation is independent of the natural cooling equation.
You then add -8.5 and -8, because the device has lowered 8.5 degrees and 8 degrees. This equals -16.5 degrees, or a decrease of 16.5 degrees.
Answer:
Step-by-step explanation:
The answer is actually
Let:
S=1+2+3+4+5+6+7+8+9+n
We know the answer to the following infinite sum:
S2=1-1+1-1+1-1+1-1+1-1+1-1+1-....= - 1/2
We can therefore solve for this sum:
S3=1-2+3-4+5-6+7-8+9-....
We add them:
S3= 1-2+3-4+5-6+7-8...
S3= +1-2+3-4+5-6+7-8...
________________
2S3= 1-1+1-1+1-1+1-1+1-....
Therefore:
2S3=S2=
