Answer:
let cost of each pound of trail mix be x any y respectively
For 2 pounds of trail mix and 5 pounds of jelly beans, the total cost is $10
2x +5y = 10.....(1)
For 8 pounds of trail mix and 3 pounds of jelly beans, the total cost is $23
8x +3y = 23.....(2)
2x +5y= 10 ....... × 4
8x +20y = 40.....(3)
8x +3y = 23 ( from (2))
(3) - (2)
17y = 17
y= 1
8x +3y = 23
8x +3 = 23
8x= 20
x= 2.5
Cost for each pound of trail mix= $2.5
Cost for each pound of jelly beans= $1
Dave would pay $16.20 and if u mean 8% tax not 8$ then Mel would pay $21.60
0.35 + 0.3x > 0.45 + 0.2x
0.3x - 0.2x > 0.45 - 0.35
0.1x > 0.1
x > 1...so it is better to use B when ur talking for more then 1 minute
Answer:
e = 56°
f = 60°
Step-by-step explanation:
Angle C = Angle A = 62
e = 180 - 2(62) = 56°
Angle A = Angle B = Angle C
(Equilateral triangle)
f = 180/3 = 60°
