He formula a=p(1+r)t is used to show the total amount owed for a loan with a simple annual interest rate. solve for r.

r = A/(Pt) -1

Step-by-step explanation:

To solve for r, we undo the operations done to it. r is ...

We undo these operations in reverse order, so we first divide by Pt:

... A/(Pt) = 1 + r

Then, we subtract 1:

... A/(Pt) -1 = r

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
