Answer:

Your answer should be 13

Step-by-step explanation:

You were given 25, so you need to work backwards. First, multiply the 25 by 3 to get 75. Then Add 6, and you end with 81. Afterwards, subtract 3 from 81 to get 78, then divide by 6 to get 13.

Pudge has three times as many apples as Ace, and Ace has twice as many as Christi. How many apples does each have if pudge has 1
mote1985 [20]

Answer:

<h3>Pudge has 12 morethan apples that is 24 apples and both Ace and Christi has not more than 12 apples together they has atmost 12 apples.The apples does each having is</h3><h3>P = Pudge's Apples =24</h3><h3>A = Ace's Apples =8</h3><h3>and C = Christi's Apples=4.</h3>

Step-by-step explanation:

Let P = Pudge's Apples

Let A = Ace's Apples

Let C = Christi's Apples

<h3>To find how many apples does each have if Pudge has 12 more than both Ace and Christi together:</h3>

Given that P = 3A  , A = 2C  and P = A + C + 12

 Substitute the value for P in P = A + C + 12 we get

3A = A + C + 12

3A-A=C+12  

2A=C+12

From A = 2C we have that  C=\frac{A}{2}

 Substitute the value  C:

 2A=\frac{A}{2}+12

 2A-\frac{A}{2}=12

 \frac{4A-A}{2}=12

\frac{3A}{2}=12

3A=12\times 2

A=\frac{24}{3}

<h3>∴  A=8</h3>

 Substituting the value of A in P=3A we get

 P = 3(8)

<h3>∴ P = 24 </h3>

   Substituting the values of P and A in P = A + C + 12

24=8+C+12

24=C+20

24-20=C

4=C

Rewritting we get

<h3>∴ C=4 </h3><h3>Hence Pudge has 12 morethan apples that is 24 apples </h3><h3>and both Ace and Christi has not more than 12 apples together they has atmost 12 apples</h3>

You and a friend each have a collection of tokens. Initially, for every 8 tokens you had, your friend had 3. After you give half
Sonbull [250]

Answer: 30 token

Step-by-step explanation:

Since, according to the question,

Initially, for every 8 tokens I had, my friend had 3.

Therefore, ratio of tokens that me and my friend is  8 : 3

Let I have 8 x tokens and my friend has 3 x tokens, where x is any number.

Then again according to the question,

After I gave half of your friend, my friend now has 18 more tokens than you.

That is, (3x + 4x) - 4x = 18

⇒ 7x - 4x = 18

⇒ 3x = 18

⇒ x = 6

Therefore , Initially the difference between me and my friend's token = 8 x - 3 x = 5 x = 5 × 6 = 30

Consider △RST and △RYX. If the triangles are similar, which must be true? A. RY/YS=RX/XT=XY/TS B.RY/RS=RX/RT=XY/TS C.RY/RS=RX/RT
trasher [3.6K]

Answer:

B.RY/RS=RX/RT=XY/TS

Step-by-step explanation:

If Triangles RST and RYX are similar, then the ratio of their corresponding sides is:

\dfrac{RS}{RY}= \dfrac{ST}{YX}=\dfrac{RT}{RX}\\$This could also be written by switching the numerator and denominators as:\\\dfrac{RY}{RS}= \dfrac{XY}{TS}=\dfrac{RX}{RT}

Out of the given options, Option B is true.
