400 Hamburgers
600 Hot dogs
Divide 2,400 by two because that's how many items they sold. You'll get 1,200.
Divide 1,200 by 3 because that's how much a hamburger costs and you'll end up with 400
Divide 1,200 by 2 because that's how much a hot dog costs and you'l end up with 600
To check, multiply 400x3 and 600x2
Then add the sums together- 1,200+1,200= 2,400
4s+7a=861
s+a=168
This can be solved using either elimination or substitution. I am going to use substitution.
Solve s+a=168 for s
s=168-a
Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861
Solve for a
672+3a=861
3a=189
a=63
Substitute 63 for a in s=168-a
s=168-63=105
So, s=105 student tickets and a=63 adult tickets
The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from the object to the observer's eye (the line of sight). If the object is below the level of the observer, then the angle between the horizontal and the observer's line of sight is called the angle of depression.
Answer:
m = -6
Step-by-step explanation:
3m = 2(m - 3)
Distribute
3m = 2m - 6
Subtract 2m from each side
3m -2m = 2m-2m -6
m = -6
