Answer:

83 + 61 = 144

83 - 61 = 22

Step-by-step explanation:

x + y = 144

<u>x - y = 22</u>

2x = 166

x = 83

83 + y = 144

y = 144 - 83

y = 61

How do i explain how the distance on the number line and opposit numbers are related
strojnjashka [21]
Hey there!

The distance on a number line is the distance that a point is from 0.
For example, if you were looking at a number line and there was a point on the number 5, that point would be 5 units away from 0.

Opposite numbers are related because they are the same distance away from 0. For example -3 and 3 are both 3 units away from the number 0.

I hope this helped! :-)

I need help with this problem, please help!!! 
OverLord2011 [107]

Answer:

Yes. (See below for explanation.)

Step-by-step explanation:

The number of servings is found by dividing the quantity available by the size of a serving. The quantity of punch is the sum of the quantities of the juices that go into the punch. The serving size of 3/4 cup is the same as 6 ounces, since a cup is 8 ounces. (3/4 × 8 oz = 6 oz)

The quantity available is (64 oz + 28 oz + 76 oz). The serving size is 6 oz. Since the units of numerator and denominator are the same, they cancel, leaving ...

... number of servings = (quantity available)/(serving size)

... = (64 +28 +76)/6 . . . . as shown in the problem statement

_____

It might not be obvious that the above ratio gives the number of servings. However, if you look at the real units, you see how it happens.

\dfrac{oz}{(\frac{oz}{serving})}= oz\dfrac{serving}{oz}=\dfrac{oz}{oz}serving=serving
