Ok, so I have to pick a first letter. I have 7 choices so that'll be my first number:
7
for the 2nd letter there are 6 options left.
This narrows down until 1 so the answer is 1 x 2 x 3 x 4 x 5 x 6 x 7 or 7 factorial. This equals 5040.
Answer:
No, its outside of the equation (shaded drawing)
Step-by-step explanation:
Yes the graph is proportional
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)
Just multiply 20 by how many days there are in a month.
