If the simple interest on $3,000 for 5 years is $1,050 , then what is the interest rate?

Step-by-step explanation:

Step 1 :Write all the given value

Given

Princilal(P)= $3000

Time(T) =5year

Intrest(I) = $1050

Rate(R) =?

Step 2 : Finding rate using simple intrest formula

We know that

I =PTR/100

or 100I =PTR

or R =100I/PT

= 100* 1050/(5*3000)

= 105 /(5*3)

= 105/15

= 7%pa

Therefore Rate is 7%pa

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
