Answer:
4b-3.2=6b-12
12-3.2=6b -4b
8.8=2b
b=8.÷2
b=4.4
The answer is B.
Step-by-step explanation:
7x4 is 28 which means you have to multiply 3x4. That gives you 12. 28:12 is the proper ratio. (Hope this helped!)
I think it is -24t+20 if you want to simplify
domain all real number
f(h(x))= 2x-4
f(h(x))=f(2x+3)=2x+3-7= 2x-4
