Evan is not correct. While 25 is 125% of 20, it was <em>not</em> 125% more. That would be adding on to the 100% already there, for a total of 225%. It's actually only 25% more because of this.
250-22 gives you 228 228/6 gives you how much each cake is, each cake is 38 grams
-3=7x-10. -7x=3-10. X=1. You can check the answer by plugging in the numbers.
Answer:
The solution of this system is
(4). (6.0,5.4)
Step-by-step explanation:
First we have to find the equation of the line represented in the table; for that we have to find it's slope 
and it's y-intercept 
and then write it in the following form:
The slope of the line we get from first two points:
thus we have
we find by putting the point 
into the function:
Thus we have
Now we have to find where this line intersects with 
; to do this we just substitute 
with :
<em>We have the x-coordinate of the intersection.</em>
We find the y-coordinate by substituting 
into :
Thus the solution to the system is
which is option 4.
Answer:
an=29.7(1/3)^(n−1)
Step-by-step explanation:
The first term, a1, is 29.7.
The common ratio, r, is 9.9/29.7 = 1/3.
The generic explicit rule is ...
an = a1·r^(n-1)
Filling in the values you have gives the explicit rule ...
an = 29.7(1/3)^(n-1)

Please note that parentheses on the exponent are essential. Without them, the expression has a different meaning entirely.
