Fugure out m. pls explain step by step.

15+0.25m=20+0.05

Step-by-step explanation:

15+0.25m=20+0.05

15+0.25m=20.05             I just added 20 +0.05

I have to move 15 to the other side of the equal sign so whenever you move something to the other side of the equal sign you do inverse operation so I am gonna subtract 20.05-15

0.25m=5.05

now I divide

20.2

the answer is 375 miles

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
