Answer:
Variable x = cost of cookies
Variable y = cost of brownies
System of equations:
2x + 3y = 9.50
10x + 6y = 20.50
Step-by-step explanation:
Variable x: $ cookies
Variable y: $ brownies
2x + 3y = 9.50
10x + 6y = 20.50
I'm not entirely sure how to explain this one, but my best advice is to just take it step by step when doing these problems. Multiple questions can feel overwhelming so just focus on one question at a time.
Answer:
because its not the average
Step-by-step explanation:
it may be in the middle of the graph but its not the average(which would be the center), and if you do the math it would end up making 7 the average
hope this helps
Step-by-step explanation:
Well in general, we can represent subtraction as: 
"z" represents the difference, and it really just represents x with y taken away. So if we were to "give back" this y value, we should get "x".
This means that: 
So one way to check, is adding the value that's being subtracted (y value) and the difference (z value), this should get you the value that is being subtracted from (x value). If you don't get the original value that's being subtracted from (x-value) then you know the answer you got is wrong.
Answer:
P=163,487,500
Step-by-step explanation: P=Ae^(kt)
151000000=145000000*e^(k5)
151000000/14500000=e^(k5)
1.04137931=e^(k5)
Ln 1.04=Ln e^(k5)
0.04=k5
k= 0.008
P=145,000,000*e^(.008*15)
P=145,000,000*e^0.12
e=2.71828
P=145,000,000*1.12749685
p=163,487,500
5000(1+.07)^2
5000(1.07)^2
5000(1.14)
5,700
Your final answer should be 5,700$. If you wanna double check you would use the equation fv=bv(1+r/m)^mt
