Question

Choose if the following sentence is true or false.
A formula is rearranged to make t the subject:
12p + t = 3m becomes t = 3m − 12p

Answer 1

true

12p + t = 3m becomes t = 3m − 12p, it's true. because

at the equation, 12p + t = 3m

here we take the 12p, and it puts to equal side

( in a positive sighn , it moves be other side of eqals, the sighn become negative ).

there for, 12p becomes -12p.

so the formula rearrange, the answer is becomes

t = 3m − 12p.
