Answer:
Step-by-step explanation:
Use the pythagorean theorem to find z first.
a = 12
b = 6
c = z
z is greater than a and b
Answer:
<em>In one year he will pay about $32 in interest</em>
Step-by-step explanation:
<u>Simple Interest
</u>
Interest is calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Steve paid a down payment of $100 for a guitar that costs $500, therefore he stills owes P=$500-$100=$400. This is the principal amount that will be paid at an interest rate of 8% = 0.08. In t=1 year, he will pay in interest:
I = $400*0.08*1
I = $32.
In one year he will pay about $32 in interest
Answer:
40
Step-by-step explanation:
let the unknown be y (x is used as times(multiplication) )
(y-17)x-6=-138
add /-6 to both sides
y-17x-6/-6=-138/-6
y-17=23
make y independent/add 17 to both sides
y-17+17=23+17
y=40
or in an easier way
-138/-6 =23
23+17=40
