John is at a local bait shop; he wants to buy bait for his fishing trip. At the store, they are selling love bait for $12 a poun

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,

$x\ge 3$

Three consecutive integers have a sum of 48 find the integers?

zavuch27 [327]

The sum of three consecutive integers is three times the middle one: if we call the middle one $x$ , the three numbers are

$x-1,\ x,\ x+1$

So, their sum is $x-1+x+x+1 = 3x$

Which is three times the middle one.

So, if the sum of three consecutive intergers is 48, the middle one must be 48/3 = 16.

So, the three numbers are 15, 16 and 17
