9x-4/x=3 ok first lets get the like terms together! So 9x+1x=10x rewrite 10x-4=3 add 4 to both sides 10x=7 then divide 10 7/10=.7 x=.7
Or you can do it this way
9x-4/x=3 combine like terms so times -4 to both sides 3*-4=-12 rewrite 9x+x=-12 combine like term (still got some) 9x+1x=10x rewrite 10x=-12 divide 10 to both sides -12/10=-1.2 rewrite x=-1.2 (I'm like 95% sure it's this one) hope this helps!!! Have a nice nite (Don't be afraid to ask me about details on this or another question)!!!
that's right the way you have it right now in the picture all adds up to 65
First we should calculate the relation between how much they make and the fuel cost so we write
(1412.42+<span>1187.92)/418.91=6.21
So that means that for every 6.21 dollars made 1 dollar of fuel must be deducted so now we calculate what they need to be deducted by:
Dan deduction = 1412.42/6.21= 227.41
Aaron deduction= 1187.92/6.21 = 191.29</span>
<span>f(x) varies directly with x.
f(x) = kx (k is the constant of proportionality)
if x = 8,
12 = 8 k
k = 12/8
k = 3/2
So the equation would be:
f(x) = (3/2)x
