Javier is buying steak for his upcoming birthday party. The Flat-iron is $5.60 per pound. The T-Bone sells for $5.44 a pound while the Strip is priced at $4.48 per pound. Javier’s other meat choice is a Porterhouse steak which is currently priced at $4.96 per pound. Which steak has theunit price of $0.34 per oz.?

Step-by-step explanation:

Divide each of these prices by 16 because we can't have the cost per pound and divide by 1 pound when we want the price per ounce. There are 16 ounces in 1 pound.

For the flat-iron, the cost per ounce is 5.60/16 = 35 cents per ounce.

For the T-bone, the cost per ounce is 5.44/16 = 34 cents per ounce.

For the Strip, the cost per ounce is 4.48/16 = 28 cents per ounce.

For the Porterhouse, the cost per ounce is 4.96/16 = 31 cents per ounce.

It appears that the one that costs 34 cents per ounce is the T-Bone.

2 5/8 is the final answer! : )

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
