Answer:
Adult’s ticket = $ 18
Child’s ticket = $ 16
Step-by-step explanation:
Adults: x
Children: y
(3x + 4y = 118) * (2) = 6x + 8y = 236
(2x + 3y = 84) * (-3) = -6x - 9y = -252
Add both equations:
-y = - 16
y = 16
3x + 4(16) = 118
3X + 64 = 118
3X = 118 - 64
X = 54/3=18
Answer:
-35
Step-by-step explanation:
this is a simple but confusing question
however,
since they said down the elevator, and the negative integers reduces, therefore we have our answer as
-35
1) Gathering the data
shadow = height = 12 feet
friend = 5 ft tall and his shadow=2 ft
Let's visualize it:
2) Since we have similar triangles, (congruent angles and proportional legs) then we can write the following proportion:
3) So the height of the electric pole is 35 ft
Quick division: $420/5 days = $84/day
