Well, since you have the value of b, the first thing you want to do is substitute that value in for b.
5a - 10(3) = 45
10*3 = 30
5a - 30 = 45
Now, to get the variable by itself (a) you have to + 30 because you have to reverse the subtraction.
5a = 75
Now, you divide by 5 to finish getting a by itself.
a = 15

Answer:
each square takes up a 10 by 10 square is you divide it into to four pieces then you use the formula for area of a circle
Step-by-step explanation:
1) 10 x 10
Find the diameter which is 5
Use the area equation Pie r squared
Divide the diameter by 2 to get radius
3.14 x 2.5 squared
19.625
at that 4 times
You get are of circles
And Shaded area is 19.625
