Answer : 21
Hope this Helps :)
Those lines on the sides of x in the equation mean "absolute value". Which is a complicated way of saying "this number will never be negative". So if x = 2 then absolute value x= 2 but if x = -2 then absolute value x still is positive 2. Because of those brackets/lines (whatever they're called). So if you're given x=2 then it's simply saying y=4(2)-1 which is y=7
Answer: 2/3 hours
Step-by-step explanation:
okay so the speed now is 850, which is 850/340 = 2.5 times the original speed
Since It's 2.5 times the original speed,
2.5x = 5/3
so x = 5/3/2.5 = 2/3
Answer:
n > 3
Step-by-step explanation:
Given
3n + 6 > 15 ( subtract 6 from both sides )
3n > 9 ( divide both sides by 3 )
n > 3
Do you have a specific equation I can help you with. I can explain them better with a problem to look at?
