Justify each step. Circle what changed and put what operation used
a. 7 + 2(x - 3) + 5x = 7 + 2x - 6 + 5x
b.
= 7 + 2x + (-6) + 5x
C.
= 7 + (-6) + 2x + 5x
d.
= 7 + (-6) + (2 + 5)x
e.
= 7+ (-6) + 7x
f.
= 1 + 7x
= 7x + 1

step-by-step explanation:

$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

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
