The answer simplified is:
a= —2x^2+7x+22
<span>This problem is an
example of ratio and proportion. A ratio is a comparison between two different
things. You are given the time of about 26.1 seconds to fold 1
shirt. Also you are given 48 shirts. You are required to find the time
in seconds to fold 48 shirts. The solution of this problem is,</span>
<span>
26.1 seconds /1
shirt = time/ 48
shirts</span>
<span>time = (48 shirts)
(26.1 seconds /1 shirt)</span>
<span>time<u> = 1,252.8
seconds</u></span>
<u>The time
it takes to fold 48 shirts is 1,252.8 seconds.</u>
7,6×4=30,4
3500×30,4/100=428,4
It brings to 428,4$
3500+428,4=3928,4$
Good lessons. Brainliest me.
Y= mx + b
y= 1/40x + 1/5= 5/200x+1 im not sure I hope I helped at least a bit
