Answer:
total: 3x + 7
Step-by-step explanation:
Nancy = x
Bill = 2x + 7
together = 3x + 7
F(-x) = 2/-x/ + 3(-x) = 2/x/ - 3x;
okay so
117° + angle a = 180° (supplementary angle)
angle a = 180 - 117
= 63°
then angle a + angle b + 81° = 180° ( angle sum property)
so... 63° + angle b + 81° = 180
144 + angle b = 180°
angle b = 180 - 144
= 36°
hope this helps.
20+5=25 then 25-4.67=20.33 so then you do 20.33/4.5=4.5 so the cost for one pound of fruit is $4.57. Hope this helps :)
