The sum of two numbers is 44 and the difference is 4 . what are the numbers?

The 2 numbers are 24 and 20

Step-by-step explanation:

x+y = 44

x-y =4

Use elimination to solve this system

x+y = 44

x-y =4

2x = 48

Divide by 2

2x/2 = 48/2

x = 24

Now we need to find y

x+y =44

24+y =44

Subtract 24 from each side

24-24+y = 44-24

y =20

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
