There is no change from $120 because she doesn't have enough money.
Answer:
Shoot I have the same question :p
Step-by-step explanation:
X + x + x + 20 + 10 = 180
(combine like terms)
3x + 30 = 180
3x=180-30
3x=150
x=150/3
x=50
The correct answer to this question is this one: "4/45"
inverse variation ---> wt = constant
let wt=k
<span>put w=4, t= 1/5 and find k
</span>
So the correct answer for k is 4/5
wt = 4* (1/5) = 4/5 = k\
so your function is
wt = 4/5 or t= 4/(5w)
now to get t, when w=9, just put w=9 in t=4/(5w)
So that makes 4/45
