Answer:
1 hotdog is $3.5.
1 drink is $2.
Step-by-step explanation:
18.50= 3x+4y(times 5)
25.50=5x+4y(times -3)
92.5=15x+20x
-76.5=-15x+-12y
16=-8y
2=y
18.50=3x+4(2)
10.50=3x+8
10.50=3x
3.5=x
Answer:
13x=13
Step-by-step explanation:
...............
The sum of measures of angles A and B is 90°
Hence the angles are complementary
- As complementary angles have sum 90°
Well plug 0 in for x and solve for y and that is the vertex of your expression
