The answer is the last one.
Corresponding sides are proportional.
For figures to be considered similar, the ratio of their sides must be proportional.
Answer:
x=-5 y=15
Step-by-step explanation:
First combine like terms and put the equations in standard form.
-6x - y = 15
5x - 2x + 2y - y = 0 equals 3x + y = 0 equals y = -3x
Go into the first equation and substitute -3x for y
-6x - (-3x) = 15
Simplify: -6x + 3x = 15
-3x = 15
x = -5
Now put -5 in for x and solve for y.
y= -3 (-5)
y=15
Answer:
So adult tickets cost £17.00 and child tickets cost £9.00
Step-by-step explanation:
2a+3c=61
2a=61-3c
a=30.5-1.5c
...
3a+5c=96, using a found above we get:
3(30.5-1.5c)+5c=96
91.5-4.5c+5c=96
91.5+0.5c=96
0.5c=4.5
c=9, and since a=30.5-1.5c
a=17
So adult tickets cost £17.00 and child tickets cost £9.00
