Answer:
Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6
For 0.4(20y+15)=x, we expand to get:
Divide through by 8
Therefore the system in slope-intercept form is:
Answer:
This is simple subtraction, considering the time span is only 5 weeks.
$1,100 - $250 = $850
So, at the end of the five weeks his new balance is <em><u>$850</u></em>
45 percent of 360 is 162.
