Answer:
D) 8.1 m
Step-by-step explanation:
Area of a circle is pi r^2
Red = r
Blue = b
Green = g
Step 1: Write as algebraic equations.
r = b + 6
g = b - 4
Step 2: Merge the two equations together to form one, by adding them together.
r + g = b + b + 6 - 4
Step 3: Simplify.
r + g = 2b + 2
Step 4: Make b the subject.
2b + 2 = r + g
2b = r + g - 2
b = 0.5(r + g - 2)
ANSWER
b = 0.5(r + g - 2)
Answer:
y = 10x - 58
Step-by-step explanation:
y-y1 = m (x-x1)
m= 10
x1= 6
y1 = 2
y - 2 = 10 ( x - 6)
y - 2 = 10x -60
y = 10x - 58
