Simplify the expression. 7C3

the formula for nCr is (n!)/(r!(n-r)!)

n=7 and r= 3. Plug in 7 for n and 3 for r in the formula

(7!)/(3!(7-3)!)

(7*6*5*4*3*2*1)/((3*2*1)(4*3*2*1))

-3a+6b=a+4b I need to solve this please.

Answers

Answer:

a*2=b

Or

a=0, b=0

Step-by-step explanation:

if a=0 and b=0, then 0=0, it'd be correct, but I'm sure that's not the answer they intend you to pick. You should still put that as one of the answers, however.

-3a+6b=a+4b

+3a     +3a

6b=4a+4b

-6b     -6b

0=4a-2b

/2 /2  /2

0=2a-b

so, we now know that b is twice the amount that a is, and actually, that's the solution for the entire thing.

So, the answer is a*2=b, because the equation works for any set of numbers, as long as it follows this rule.
