Answer:
x = 10 meter
y= 20 meter
shadw of a man = 10 meters
If the measure of angle A = 40 and B is a complement of A, then the measure of angle B = 50. If C is a supplement of B, then the measure of angle C = 130.
the measure of angle A = 40
the measure of angle B = 50
the measure of angle C = 130
Hope this helps!
Let x = roller coaster ticket
let y = boat ride ticket
x + y = 10
4x + 3y = 37
x = 10 - y
4x + 3y = 37
4(10-y) + 3y = 37
40 - 4y + 3y = 37
-y = 37 - 40
-y = -3
y = -3/-1
y = 3
x = 10 - y
x = 10 - 3
x = 7
x = 7 ; y = 3
4x + 3y = 37
4(7) + 3(3) = 37
28 + 9 = 37
37 = 37
Three more than nine times a number is at least five times the number.
