Answer:
5x - 4 = 56
2x + 3 = 27
Step-by-step explanation:
2(5x - 4 + 2x + 3) = 166
10x - 8 + 4x + 6 = 166
14x - 2 = 166
+ 2 +2
14x = 168
divide both sides of the equal sign by 14
12
5(12) - 4 = 60 - 4 = 56
2(12) + 3 = 24 + 3 = 27

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
We Know, 1 cm = 1/100 m
Then, 375 cm = 375/100 m = 3.75 m
So, your final answer is 3.75 m
Hope this helps!
