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:
21
Step-by-step explanation:
Find 60% of 35.
To do this you have to multiply 60 by 35, and divide that answer by 100, and your answer should that number. In this case, the answer is 21, because 60x35 is 2100, and 2100/100 is 21.
