I have to choose a variable and write inequality
For less than or equal to I'm using these keys <|
Cuz I don't Jon how to show when I type
1. A van can hold a maximum of 8 passengers
I wrote V <| 8
V is less than or equal to 8
2. To apply for a job you need to type at least 80 words a minute
t <| 80
T is less than or equal to 80
Are these right?
Algebra inequality -
most folks use <= or >=, not <| or >|
#1 is correct,
#2 should be t >= 80 where t = typing speed
"at least" means "greater than or equal to". It's a minimum value.
"at most" gives a maximum value, as in #1 above.
