John bought a total of 12 bags of candy for Halloween. Each bag of candy was either a bag of Snickers or a bag of Milky Way bars.
He spent $4 on each bag of Snickers.
He spent $5 on each bag of Milky Way bars.
John spent a total of $58.
How many more bags of Snickers than Milky Way bars did John purchase?

John bought 2 Snickers bags and 10 Milky Way bags.

Step-by-step explanation:

Let x be number of Snickers bags. Let y be number of Milky Way bags.

Systems of Equations:

4x+5y=58

x+y=12

4x+5y=58

y=-x+12

4x+5(-x+12)=58

4x-5x+60=58

-x=-2

x=2

12-2=10

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
