Answer: The coordinate of the solution is (0.25,-0.5)
Step-by-step explanation:
the solution is (0.25,-0.5) because when you graph them on a graph, they both intercept at that point.
So assuming simplet interest
find the change to find the interest
change=186000-129000=57000
simple interest=time times rate times principal
time is in years (8)
rate is in decimal
principal is amount invested (129000)
so
interest is 57000
57000=(8)(r)(129000)
57000=1032000r
divide both sides by 1032000
0.05523255813953488372093023255814=r
or
5.523255813953488372093023255814%
rounded
5.5%
We can suggest this equation.
(6x+x)+(6x+x)+110º+110º=360º
7x+7x+220º=360º
14x=360º-220º
14x=140º
x=140º/14
x=10º
Answer. x=10º
Answer:
25000(1-.14)^t
Step-by-step explanation:
it's just a simple decreasing equation it's your start number 1 minus your percentage because we're decreasing and to the power of t which equals time
Kate has $37, Mary has $48, and Amy has $74.
<h3><u>Equations</u></h3>
Given that Mary, Kate and Amy have a total of $159, and Mary has $11 more than Kate, while Amy has twice as much money as Kate, to determine how much money each girl has, the following calculation must be performed:
- M = K + 11
- A = 2K
- K = K
- K + 11 + 2K + K = 159
- 4K = 159 - 11
- K = 148 / 4
- K = 37
So Kate has $37, Mary has $48, and Amy has $74.
