57 times 71 = 4047 Hope that helps!
This is a system of equations. The best way to solve it is by realizing that you have two equations equal to y. Since y = y, it follows that
. Solving for x, you get 4.
Then, substitute 4 into one of the original equations to find y.
.
The solution is
. I have attached a graphical representation of the solution as well.
Answer:
Annually: Total Amount = 1611.76, Interest Amount = 711.76
Semiannually: Total Amount = 1625.50 , Interest Amount = 725.50
Quarterly: Total Amount = 1632.62 , Interest Amount = 732.62
Step by Step Explanation:
We can see from the table that the factor that we need to multiply with 900 in order to get amount for compounded annually is 1.7908477. Therefore, our total amount is 1.7908477*900 = 1611.76 and interest earned is 1611.76-900 = 711.76.
The factor that we need to multiply with 900 in order to get amount for compounded semiannually is 1.8061112. Therefore, our total amount is 1.8061112*900 = 1625.50 and interest earned is 1625.50-900 = 725.50.
The factor that we need to multiply with 900 in order to get amount for compounded semiannually is 1.8140184. Therefore, our total amount is 1.8140184*900 = 1632.62 and interest earned is 1632.62-900 = 732.62.
You would do
51-5= 46
then you would divide
46/2= 23
so Susan is
23+5=28
Susan is 28 years old and her sister is 23
28+23=51
If x² = 196, then we must do the inverse (square root) to find x. However, the square root of any positive number will always be ± (plus or minus).
That means you have to do:
√196 = x
x = <span>±14.
We can check this by doing:
14 </span>× 14 = 196
-14 × -14 = 196
Therefore the answer is B) -14, 14.
