Temperature at nightfall = -5 + 78 - 32 = 41 degree Farenheit
If 4/5 do, then 1/5 dont
1/5=x/100
x=20
20%
16a. 21cm. bc when it has 10 grams it moves half of that to 5cm so divide 42 by 2 and you get 21cm
17. remember y=mx+b; m is slope and b is y-intercept
you have to put your equation from point slope to y=mx+b
4x+y=6
subtract 4x from each side
y=-4x+6
slope = -4
y-intercept= 6
hope this helped :)
