Mrs. jackson purchased 5-pound package of ground beef for $12.40. she decided to use 8 ounces each day for dinner recipes. what was the cost of ground beef per meal?

$1.55

Step-by-step explanation:

Okay, we know that there are 16 ounces in one pound. Since Mrs. Jackson purchased 5 pounds, we need to multiply the amount of ounces in one pound by 5.

16 × 5 = 80

Now that is out of the way, we need to find out how many meals she could have by using 8 ounces of the meat each day.

80 × 8 = 10

Now we divide the amount of meals with the cost of the ground beef.

12.40 ÷ 8 = 1.55

It cost $1.55 for ground beef per meal

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
