At yo-yo yogurt, the scale says that sara has 8 ounces of vanilla yogurt in her cup. her father’s yogurt weighs 11 ounces. how many pounds of frozen yogurt did they buy altogether? express your answer as a mixed number.

Step-by-step explanation:

You know that Sara has 8 ounces of vanilla yogurt in her cup and her  father’s yogurt weighs 11 ounces. Then, the total ounces of frozen yogurt they buy altogether is:

The next step is to make the conversion from ounces to pounds.

You need to remember that:

Therefore:

This result expressed as a mixed number, is:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
