Fred can drink 8 3/4 sodas in 5 minutes at thus rate how many sodas can fred drink in 2mintues

1 answer:

5 0

He can drink 2/5 of the 8 3/4 sodas.

$\frac{2}{5} x 8 \frac{3}{4} = \frac{2}{5} x \frac{35}{4}$

The answer is 7/2 or 3 1/2 sodas.

Of course, Fred would be better off is he drank water instead of soda. :-)

What is the value of y if f||n<br> ?????

Elenna [48]

Answer:

y = 148°

Step-by-step explanation:

4x - 18 = 2x + 12 (alternate exterior angles are congruent)

Collect like terms

4x - 18 = 2x + 12

4x - 2x = 18 + 12

2x = 20

Divide both sides by 2

x = 10

y = 180 - (2x + 12) (linear pair theorem)

Plug in the value of x

y = 180 - (2(10) + 12)

y = 180 - (20 + 12)

y = 148°

A bookcase has two shelves. The top shelf has 10 more than 1/3 the number of books on the bottom shelf. There are 12 books on th

kobusy [5.1K]

Answer: b.14

Step-by-step explanation:

We have two shelves, the top shelf $s_{t}$ and the bottom shelf $s_{b}$ .

Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:

$s_{t}=10+\frac{1}{3}s_{b}$ (1)

Then, we are told there are 12 books on the bottom shelf:

$s_{b}=12$ (2)

Substituting (2) in (1):

$s_{t}=10+\frac{1}{3}(12)$ (3)

$s_{t}=10+\frac{12}{3}$ (4)

$s_{t}=14$ (5) This is the number of books on the top shelf

Hence, the correct option is b.

I need help please explain it bc I don’t understand it

For the two lines to be parallel, the angles labeled 1 and 2 must be equal.
m 1 and m 2 have to be equal.

(5 - 3x) = (5x - 11)
Solve for x:
16=8x
2=x

X has to be 2.
