Answer:
327.6 €
Step-by-step explanation:
you can solve with an equation
1£ : 1.17€ = 280£ : x
1 : 1.17 = 280 : x
x = 1.17 * 280 : 1
x = 327.6
-------------------
check
1 : 1.17 = 280 : 327.6
0.85 = 0.85
the answer is good
------------------------------------

Answer:
w(9) = -20
Step-by-step explanation:
In order to find this, take the w function and input 9 in for all the x values.
w(x) = -2x - 2
w(9) = -2(9) - 2
w(9) = -18 - 2
w(9) = -20
The ration is 170 adults:150 children, or 170/150We can factor out a 10 from both numbers, which leaves us with
17 adults/15 children.17 and 15 have no other factors, so that's the smallest ratio we can have.
