Answer:
c
Step-by-step explanation:
so (13-9)*7 so 13-9 is 4.
so 4*7= 28
and then you have to do 4+3 = 7
so 28/7 will be 4 you the answer is 4.
Work Shown:
x - xy = z
x*1 - x*y = z
x*(1 - y) = z .... distributive rule in reverse
x = z/(1-y) ..... divide both sides by (1-y)
The distributive rule is a*(b+c) = a*b+a*c. You can also say a*(b-c) = a*b-a*c. In this case, we factored out the common factor x.
