Answer:

It's A.

Step-by-step explanation:

A.    3(4x - 2) = 6(2x - 1)

Applying the Distributive Law:

        12x - 12 = 12x - 12

We see that the left side of the equation equals the right side. this is an identity and we can assigned any value we like to x.

This means that there are infinite solutions to equation A.

Item 9 Find the annual interest rate. I=$562.50, P=$1500, t=5 yearsI=$562.50, P=$1500, t=5 years The annual interest rate is %.
Anton [14]
Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%

Hope it helps:-)
