Answer the following:
Which one of the following inequalities describes "half of $x$x is no more than four"?
$2x\le4$2x≤4
$2x\ge4$2x≥4
$\frac{x}{2}\le4$x2≤4
$\frac{x}{2}\ge4$x2≥4
Solve for $x$x.
Consider the following situation:
"$2$2 less than $4$4 groups of $p$p is no more than $18$18".
Construct and solve an inequality for the following situation:
"$5$5 groups of $p$p, added to $5$5, is less than $25$25."
Construct and solve an inequality for the following situation:
"The sum of $2$2 groups of $x$x and $1$1 is at least $7$7."
