3a + b = 54...when b = 9
3a + 9 = 54
3a = 54 - 9
3a = 45
a = 45/3
a = 15 <===

Salutations!

3a+b = 54

Replace b as 9

3a+9=54

3a=54-9

3a=45

a= 45/3

a=15

Thus, your answer is 15

Hope I helped (:

Have a great day!

Because of the symmetry, we can just go from x=0 to x=2 to find the area between 
<span>y = x^2 and y = 4 </span>

<span>that area = ∫4-x^2 dx from 0 to 2 </span>
<span>= [4x - (1/3)x^3] from 0 to 2 </span>
<span>= 8 - 8/3 - 0 </span>
<span>= 16/3 </span>

<span>so when y = b </span>
<span>x= √b </span>
<span>and we have the area as </span>
<span>∫(b - x^2) dx from 0 to √b </span>
<span>= [b x - (1/3)x^3] from 0 to √b </span>
<span>= b√b - (1/3)b√b - 0 </span>

<span>(2/3)b√b = 8/3 </span>
<span>b√b =4 </span>
<span>square both sides </span>
<span>b^3 = 16 </span>
<span>b = 16^(1/3) = 2 cuberoot(2) </span>

Answer:

The probability of spinning red is \frac{1}{3}, the probability of spinning a 1 is \frac{1}{6}, the probability of spinning an odd number is \frac{1}{2}, and the probability of spinning a 9 is 0.

Step-by-step explanation:

Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is \frac{2}{6} or \frac{1}{3}. Since there are only one 1 tile, the probability of spinning a 1 is \frac{1}{6}. Since there are three odd numbers, the probability of spinning an odd number is \frac{1}{2}. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.
