48.5 inches is the answer
Answer:
B. -4
Step-by-step explanation:
We want to find x such that f(x)=18.
We need to therefore solve 9x+54=18 forx.
9x+54=18
Divide both sides by 9:
(9x+54)/9=18/9
9x/9+54/9=18/9
Simplify:
x+6=2
Subtract 6 on both sides:
x=2-6
Simplify
x=-4.
So f(-4) should have value 18.
Let's check.
f(x)=9x+54
f(-4)=9(-4)+54
f(-4)=-36+54
f(-4)=18
So the answer is B.
168/4 to get the bike and the accessories to get 42
42x3=126
it lost 100 - 60 = 40% of its games ( = 0.40)
Total games played = 24 / 0.40 = 60 answer
$1.44
each one cost 0.24
0.24 x 6 = 1.44
