Answer:

21) x = 0

23) x = 7

Step-by-step explanation:

In a parallelogram, the opposite sides are congruent. Using this fact, we can create equations for both problems.

21)

$2x + 18 = 18$

Subtract 18.

$2x = 0$

Divide by 2.

$x = 0$

23)

$2x - 3 = 11$

Add 3.

$2x = 14$

Divide by 2.

$x = 7$

Scrat [10]

Answer:

$12x+7y\le 63$
$x\ge 3$

Step-by-step explanation:

Let us assume that, x be the amount of live bait and y be the amount of natural bait.

The price of live bait is $12 per pound and that of the natural bait is $7 per pound.

As John has a budget of $63, so he spend any amount less than or equal to $63, not more than that. So the inequality for this will be,

$12x+7y\le 63$

John would like to get at least 3 pounds of live bait, so the inequality for this will be,

$x\ge 3$
