sausage 3.25
turkey 2.85

how much more does 1 1/4 pounds of beef cost than 1 1/4 pounds of turkey?
question 2. brad has 10 dollars to spend at ruby's. he orders 1/2 pound of sausage and 1 1/4 pounds of chicken. how much money will he brad have after he pays for this order?

A. $1.75

B. $5.25

Step-by-step explanation:

Rubys market sells smoked meats. The price of different type of meat is as given in the table.

Beef = $4.25 per pound

Chicken = $2.50 per pound

Sausage = $3.25 per pound

Turkey = $2.85 per pound

A. pounds of beef costs = 1.25 × 4.25 = $5.31

pounds of turkey costs = 1.25 × 2.85 = $3.56

Beef costs more than turkey = 5.31 - 3.56 = $1.75

B. Brad ordered 1/2 pound of sausage = 0.5 × 3.25 = $1.625

and pound of chicken = 1.25 × 2.50 = $3.125

Brad have to pay total = 1.625 + 3.125 = $4.75

Brad has $10.00 to spend, he paid $4.75.

Now Brad is left with = 10.00 - 4.75 = $5.25

A. Beef cost $1.75 more than turkey.

B. Now Brad has $5.25 after he pays for his order.

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
