Consecutive integers are numbers one after the other on the number one (ie. 1,2,3,4,5 or 203,204,205).
times= multiplication
sum= addition
more than= addition
is= equal sign
x= first integer
x+2= second integer
x+3= third integer
3(x + (x + 2))= 5(x + 3) + 8
add inside parentheses
3(2x + 2)= 5(x + 3) + 8
multiply 3 and 5 by their parentheses
(3*2x) + (3*2)= (5*x) + (5*3) + 8
multiply in parentheses
6x + 6= 5x + 15 + 8
6x + 6= 5x + 23
subtract 5x from both sides
x + 6= 23
subtract 6 from both sides
x= 17 first integer
x + 1= 17 + 1= 18 second integer
x + 2= 17 + 2= 19 third integer
CHECK:
3(x + (x + 2))= 5(x + 3) + 8
3(17 + (17 + 2))= 5(17 + 3) + 8
3(17 + 19)= 5(20) + 8
3(36)= 100 + 8
108= 108
ANSWER: The three consecutive integers are 17, 18 and 19.
Hope this helps! :)

Answer:
$471.65
Step-by-step explanation:
-The value of the laptop after each year is calculated by the formula:
where:
is the value at time t
is the initial value
is the rate of depreciation
is the time
#We substitute the values to solve for the value after 3 years(2010-2007=3):
Hence, the value of the laptop in 2010 is $471.65
