Answer:
312
Step-by-step explanation:
First we need to determine the width
A = l*w
6.2 * 10 ^3 = 1.55 * 10 ^2 * w
Divide each side by 1.55 * 10 ^2
6.2 ^ 10 ^3 /1.55 * 10 ^2 = 1.55 * 10 ^2 * w / 1.55 * 10 ^2
Changing from scientific notation to standard
6200/155 = w
40 = w
Then we need to determine the perimeter
P = 2(l+w)
P = 2( 155+40)
P =2( 195)
P = 390
Now multiply by the price
390 *.80
312
X=15
you do 2(5x-5)=(6x+50) and simplify, then you get x=15.
y=7
Once again, you do (5y+5)=(7y-9) and simplify. you get y=7.
please leave a thanks and mark brainliest if you can
Y-5 = 6x-24 ad 5 to both sides to get y alone
y=6x-19 the slope of the line is 6 and the y-intercept is -19 or (0,-19)
m = 6 or 6/1
