Area of a Circle is directly proportional to the square of it's radius. So, if radius is increased by 3, area will increase by 3^2 = 9
In short, Your Answer would be: Option C
Hope this helps!
If 3x>96, dividing both sides by 3 we get that x>32, therefore only E is an acceptable answer
26 is the answer to 40% of 65
Answer:
a = -1/2
b = 2
Step-by-step explanation:
Step 1: Rewrite 1st equation
-b = -5 - 6a
b = 5 + 6a
Step 2: Substitution
4a - 3(5 + 6a) = -8
Step 3: Solve
4a - 15 - 18a = -8
-14a - 15 = -8
-14a = 7
a = -1/2
Step 4: Plug in <em>a</em> to find <em>b</em>
6(-1/2) - b = -5
-3 - b = -5
-b = -2
b = 2
