4x - 3y = 22 ⇒  4x - 3y = 22 ⇒ 4x - 3y = 22
2x  -  y = 10 ⇒2(2x - y) = 10 ⇒ <u>4x - 2y = 10</u>
                                                          5y = 32
                                                          <u>5y</u> = <u>32
</u>                                                           5      5<u>
</u>                                                            y = 6.4
                                              4x - 3(6.4) = 22
                                                4x - 19.2 = 22
                                                <u>     + 19.2 + 19.2
</u>                                                            4x = 41.2
                                                           <u>4x</u> = <u>19.2</u>
                                                            4        4
                                                             x = 4.8
                                                        (x, y) = (4.8, 6.4)

How do you rename a mixed number as a fraction khan academy.
elena-s [515]

Answer:

There's no answer choices but I can give you an example.  

Step-by-step explanation:

  1. Let's say you have \frac{25}{4}.  
  2. Think about what the closest whole number 25/4 will give you.  Since 24 and 25 are close you can do 24/4 and get 6.  
  3. Now since you took one number away from the 25 you have a remainder.  
  4. Since the denominator is 4 your final answer would be 6\frac{1}{4}.  

Hopefully this helps.

- A new rectangular lawn has a
disa [49]

The number of bags of grass seed that are needed to seed the new rectangular lawn is approximately 19 bags .

<h3>Perimeter of a rectangle</h3>

The perimeter of a rectangle is the sum of the whole sides of the rectangle.

Therefore,

perimeter of the rectangle = 298 ft

The width is 67 ft.

Hence

perimeter of rectangle = 2(l + w)

where

  • l  = length
  • w = width

Therefore,

298 = 2 ( l + 67)

298 = 2l + 134

298 - 134 = 2l

164 = 2l

l = 164 / 2

l = 82 ft

Therefore,

area of the rectangle = 82 × 67 = 5494 ft²

285 ft² = 1 bag of grass seed

5494 ft² = ?

cross multiply

number of bag of grass seed to fill the new rectangular lawn = 5494 / 285

number of bag of grass seed to fill the new rectangular lawn = 19.2771929825
