Using the guess and check technique, find two numbers that satisfy both conditions.

the sum of the two numbers is 56.

the second number is seven less than two times the first number.

what is the value of the first number, x?
19
21
31
35

B.

Step-by-step explanation:

21 X 2 = 42

42-7 = 35

35 + 21 = 56

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.
