Given:

Kelly purchased 5 containers of ice cream for a party.

Each container holds 8 cups of ice cream.

Her brother ate 2 cups of ice cream.

One serving of ice cream = 2/3 of a cup.

To find:

Number of servings of ice cream will be left for the party?

Solution:

We have,

1 container = 8 cups of ice cream

5 containers = 5×8 = 40 cups of ice cream

Her brother ate 2 cups of ice cream. So, remaining cups of ice cream is

40-2=38 cups

Now,

\dfrac{2}{3} of a cup = 1 serving

1 cup = \dfrac{3}{2} serving

38 cup = 38\times \dfrac{3}{2} serving

            = 19\times 3 serving

            = 57 serving

Therefore, 57 servings of ice cream will be left for the party.

Tell whether the angles are complementary or supplementary. Then find the value of x.
Paha777 [63]
The angles are complementary meaning they =90 degrees.

So take (x-20) and x, and write this equation,

x-20+x=90

2x-20=90

move the 20 over

2x-20=90
    +20  +20

2x=110

x=55.

You can check it by plugging it back in,

(55-20)=35
and
x=55

35+55=90.

Thus, you know your answer is correct.
