I believe by the first equation they are referring two a representation of the total amount of money made up by the two types of coins. I found this to be 0.05x + 0.10y = 3.50
In my work I solved for the amount of each coin- I assume this is what the final step of your problem entails. If you need any help understanding/ I misinterpreted something please feel free to comment and ask :)
#5c coins or x= 36
#10c coins or y= 17
Answer:
hi there!
The correct answer to this question is 7.51
Step-by-step explanation:
you would use tangent for this question
tan(43) * 7 equals x
<span>.09X+.08(7,000-X)=588
.09X+560-.08X=588
.01X=588-560
.01X=28
X=28/.01
X=2,800 AMOUNT INVESTED @ 9%.
7,000-2,800=4,200 AMOUNT INVESTED @ 8%
PROOF:
.09*2,800+.08*4,200=588
252+336=588
588=588</span>

Step-by-step explanation:
In math, when a number is squared, it means it has been multiplied by itself. For instance, two squared equals two times two, or four.
In this same case x^2---> x * x
x times x ---> x^2
Answer:
is the required relationship.
Step-by-step explanation:
We have bee give that the Yusuf earned a total of $180 from drying 12 identically-price pictures at a festival.
That means if we count earning for one picture is:
We need to find the relationship between P and E
Where, P is the price of the picture
And E is the earning.

If we put different values of P we will get the earning for the number of pictures.
