Let h = the number of hours Marta works
Her savings in her account can be calculated by:
840 + 15h
This needs to be at least $2650 for her trip, so an inequality to solve:
840 + 15h ≥ 2650, where h is the number of hours worked
Now solve:
15h ≥ 1810
h ≥ 1810/15
h ≥ 
Marta needs to work at least
hours in order to have enough money for her trip.
Answer:
the numbers are 
Step-by-step explanation:
Let
x-------> the smaller even consecutive integer
x+2-------> the larger even consecutive integer
we know that

solve for x

The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
------> the solution (must be positive)
therefore
the numbers are 
First you would have to convert , so 12 inches = 1 foot . So do 12 X 16= 192inches, then subtract 192-6=186inches should be the difference IN INCHES. If you need it in feet divide 186 by 12 which should give you 15.5feet
