You divide 3/5 and then you get a decimal 0.6. Then you convert it to a percentage
So, ($299.95)(. 30) = $89.99
$299.95 - $89.99= $209.96
($209.96)(.05)=$10.50
$209.96 + $10.50 = $220.46

Answer:
-1
Step-by-step explanation:
The required relation is ...
7n = n^2 -8
0 = n^2 -7n -8 . . . . put in standard form
0 = (n -8)(n +1) . . . . factor
Solutions are n=8 and n=-1.
The negative solution is -1.
15/4 would be your answer
Answer:
Both equations, when we replace the solution, generate identities.
Step-by-step explanation:
We are given the following system:
y = x - 7
y = -4x + 3
We are given the following solution.
(2,-5).
First equation:
We have to show that when x = 2, y = -5. So
y = x - 7
-5 = 2 - 7
-5 = -5
So ok
Second equation
We have to show that when x = 2, y = -5. So
y = -4x + 3
-5 = -4(2) + 3
-5 = -8 + 3
-5 = -5
We generate both identities, so the solution is checked.
