B + 4b = 8
You have to combine the like terms and then divide both sides by the coefficient to isolate the variable b.
<em>b + 4b = 8
</em>5b = 8
(5b / 5) = 8 / 5
b = 1.6
Since it says to round to the nearest hundredth, I would just put a zero right after the tenths place.
b = 1.60

Hey there!
Here is your answer:
<u>The proper answer to this question is "40".</u>
Reason:
<u>40/x=100/45</u>
<u>(40/x)*x=(100/45)*x - we multiply both sides of the equation by x</u>
<u>40=2.22222222222*x - we divide both sides of the equation by (2.22222222222) to get x</u>
<u>40/2.22222222222=x </u>
<u>18=x </u>
<u>x=18</u>
