Answer:
It's ind of confusing, but you have to think of the vairables as numbers. so pretend R is a number so you divided it by V, but change your number back to R
3.) R ÷ V = I
I belive 4.) would be 2÷ R- D = T
Step-by-step explanation:
It would equal 5 x 10 ^ 10
because 10 ^ 10 is 10 billion and 9 x 10 billion is 90 billion and 4 x 10 billion is 40 billion. so, 90 billion - 40 billion. that's 50 billion, and that can be turned into 5 x 10 ^ 10.
