The answer is 48 can someone explain how?
mestny [16]

Answer:

<h2>48</h2>

Step-by-step explanation:

(1)

apple × apple × 2apple = 54

2apple³ = 54    <em>divide both sides by 2</em>

apple³ = 27 → apple = ∛27

apple = 3

(2)

apple + apple × green_apple = 24   <em>substituite apple = 3</em>

3 + 3 × green_apple = 24        <em>subtract 3 from both sides</em>

3 × green_apple = 21         <em>divide both sides by 3</em>

green_apple = 7

(3)

strawberry - bannana - banana = 0 → strawberry = 2banana

(4)

strawberry + banana + cherry = 24     <em>substitute from (3)</em>

2banana + banana + cherry = 24

3banana + cherry = 24

(5)

apple + banana - cherry = -1          <em>substitute apple = 3</em>

3 + banana - cherry = -1         <em>subtr3 from both sides</em>

banana - cherry = -4

Add both sides of (4) and (5)

 3banana + cherry = 24

<u>+banana - cherry = -4       </u>

4banana = 20       <em>divide both sides by 4</em>

banana = 5

Substitute it to (4):

3(5) + cherry = 24

15 + cherry = 24      <em>subtract 15 from both sides</em>

cherry = 9

Substitute to the last equation:

3 + 5 × 9 = 3 + 45 = 48

20/10 as a mixed number
Minchanka [31]
20/10 as a mixed number:

20 ÷ 10 = 2.

10 goes into 20 two times. So 20/10 as a mixed number is a whole number: 2. 

20/10 = 2

30 POINTS HURRY <br> will give brainliest
coldgirl [10]

Answer:

(1,4) IS THE ANSWER. I 100% believe that's the answer

Step-by-step explanation:

I can't explain it. (Next time when you get the same kind of question just look for a clear white paper. Cut it and make sure it's the size as the graph. Then put it on the computer screen then trace the shape that's on the graph and label the points like how they're labeled in your graph. After that, as the paper is one the screen of your computer, place a pencil or a pen on the paper and make sure it's aligned in the center of the graph. Press the pencil or pen a bit hard so the paper won't slide or fall out. After that rotate the paper to the ___degrees that's stated in the question. If the rotation is clockwise go clockwise. If the rotation is counterclockwise go counterclockwise. After that you'll get the answers.)
