saveliy_v [14]

Answer: 1 \frac{3}{16}\ lb

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:

total_{(ounces)}=8\ oz+11\ oz\\\\total_{(ounces)}=19\ oz

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

You need to remember that:

1\ lb=16\ oz

Therefore:

total_{(pounds)}=(19\ oz)(\frac{1\ lb}{16\ oz})=\frac{19}{16}\ lb

This result expressed as a mixed number, is:

total_{(pounds)}=1\frac{3}{16}\ lb

jeka94

Answer:

1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies

2) Now let's consider any real number a no matter positive or negative we will have that:

a-a =0

Or in the other case:

-a -(-a) =-a +a=0

So then we can conclude that the expression is a general rule and is true

Step-by-step explanation:

For this case we can verify if the following expression is true or false:

The sum of x and it’s opposite is always zero?

If we want to proof this we need to show that for any number is true.

1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies

2) Now let's consider any real number a no matter positive or negative we will have that:

a-a =0

Or in the other case:

-a -(-a) =-a +a=0

So then we can conclude that the expression is a general rule and is true
