Interest rate = 5.25%
<u>Step-by-step explanation:</u>
Simple Interest = Pnr = 4252.50
n = time = 54 months = 4.5 years
r = rate of interest = ?
P = 18,000
r = SI/Pn = 4252.50 / 18000× 4.5
= 0.0525 = 5.25%
Plug x=3 into the equation:
5(3)+2
And simplify:
15+2
17
You would do 5 divided by 4
the question is tells us that the sandwiches are being shared equally so it is the total amount. it is being distributed to 4 friends meaning it is being divided by 4.
5 divided by 4 = 1.25
they all got 1.25 of the sandwiches
X=3 because you have to isolate the variable by dividing each side by factors that don’t contain the variable .
