The sum of two numbers is 18 and the difference is 10. What are my two numbers?​

The two numbers are 14 and 4

Step-by-step explanation:

Let x and y be the two numbers

x+y = 18

x-y = 10

Add the two equations

x+y = 18

x-y = 10

2x    = 28

Divide by 2

2x/2 = 28/2

x = 14

Now find the other number

x+y =18

14+y = 18

y = 18-14

y=4

The two numbers are 14 and 4

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.
