Question

A video game gives you 100 seconds to complete the level and move to the next level. you are halfway through the level after 55 seconds. write and solve an inequality to find how much time you have left to complete the level.

Answer 1

so 100 seconds total
55 seconds used
you must beat the level in LESS THAN so
x= times you have
55+x<100
subtract 55 form both sides
x<45
so you have to take less than 45 seconds
