At a wildlife centre adult entry $12 and child entry $8 i pay for two adult and 3 childre with a $50 note how much change

Hi!

Let's write this as an equation.

12 · 2 + 8 · 3

24 + 24

48

You have to pay $48. You payed $50.

50-48 = 2

You get $2 change

Hope this helps! :)

to complete this square you have to rotate about the origin 270 degrees clockwise.

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
