4 0

Answer:

6.48%

Step-by-step explanation:

the rule of the simple interest is:

I=PRT

but here we want the rate, and we have I and P and T

so put the rate on 1 side, and all the given numbers in other side

the rule will be like this:

R=I/PT

R=4320/6000×9

R=6.48%

Answer:

Step-by-step explanation:

4y - 2(5 - y + 4) = 4y - 2(9 - y)

= 4y + 9*(-2) - y *(-2)

= 4y - 18 + 2y {Combine like terms 4y and 2y}

= 6y - 18

6y - 18 = 6*y - 6*3

= 6(y - 3)

6y- 18 = 2 *3y - 2*9

= 2(3y -9)

2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)

Others are not equivalent
