Question

All numbers less than or equal to 87 and greater than or equal to 83

Answer 1

Answer:

$83\leq x\leq 87$

Step-by-step explanation:

Split the words at "and" and solve one piece at a time. (when a function has "or equal to", use the ones with the line under $\leq \geq$) Let x be the unknown value

"less than or equal to 87"

$x\leq 87$

"greater than or equal to 83"

$x\geq 83$

Put them together by putting x in the middle. Don't forget to make the signs face the right way:

$x\leq 87\\x\geq 83\\83\leq x\leq 87$

Done.
