Answer:
y = -2x +20
6x - 5y = 12
Put the value of y in 2nd equation
6x - 5( -2x +20 ) = 12
6x +10x -40 = 12
16x = 12 +40
16x = 52
x = 13/4
Putting the value of x in equation 1
y = -2x +20
y = -2(13/4 ) +20
y = 27/2

1 bag per 5 minutes.
If you divide 15(total amount of min) by 3(bags of popcorn you popped) you will see you popped 1 bag per 5 minutes.
Now its say per minutes, then, you will have to say 1/5 bag per minutes.
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
A semicircle is given with radius of 3cm .
And we need to find the perimeter of the semicircle . We know the perimeter as ,
Perimeter = πr
Perimeter = 3cm × π
Perimeter = 3π cm .
Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,
Perimeter = 3π + 6 cm
We were supposed to give answers in terms of π .
<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>
5 to the 4th power would be one way
