Two numbers are in ratio 5: 3,if the differ by 18 what are the numbers

45

27

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

5/3 = x/y

The numbers differ by 18

x - y = 18                      Add y to both sides

x = 18 + y                      Substitute for x in the ratio

5/3 = (18 + y)/y             Cross multiply

5y = 3(18 + y)               Remove the brackets

5y = 54 + 3y                Subtract 3y from both sides

5y - 3y = 54 + 3y-3y    Combine

2y = 54                        Divide by 2

2y/2 = 54/2    

y = 27

The smaller number is 27

x = y + 18

x = 27 + 18

x = 45

The larger number is 45

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
