Anit [1.1K]

\text{Answer : Number of \$45 shares} =120

\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355

Explanation:

Let Number of $45 shares be x

Let number of $ 25 shares be 3x-25

According to question,

x+3x-5=475\\\\4x-5=475\\\\4x=475+5\\\\4x=480\\\\x=\frac{480}{4}\\\\x=120

So,

\text{Number of \$45 shares} =120

\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355

madreJ [45]

Answer:

The cost of traveling 25km would be $3000.

You can travel 35 km for $4200.

Step-by-step explanation:

Consider the provided information.

For 30km cost $3,600.

30 km = $3600

Divide both sides by 30.

\frac{30}{30}\text{ km}=\frac{3600}{30}

1 \text{ km} =120 ....(1)

The cost of 1 km is $120.

Part (A) what would be the cost of traveling 25km

Multiply both the sides of equation 1 by 25.

25 km = 3000

Hence, the cost of traveling 25km would be $3000.

Part(B) How far could you travel for $4,200?

Divide 4200 by 120.

\frac{4200}{120}=35

Hence, you can travel 35 km for $4200.

Greetings, Agent OOZero. Your mission, if you choose to accept it, is to use the
Olegator [25]

Answer:

Gertrude's favorite is <em>George Burn</em>

What we know from the beginning:

<u>Comedians</u>:

  • George Burn
  • Jack Benny
  • David Letterman
  • Jerry Springfield

<u>Lucy</u>: Jerry Springfield is her favorite

<u>David</u>: Does not like David Letterman

<u>Gertrude</u>: Does not like David Letterman, Does not like Jack Benny anymore

Solving:

  • Since we know that <em>Jerry Springfield is Lucy's favorite</em>, he is not longer an option. This leaves George Burn, Jack Benny, and David Letterman.
  • David and Gertrude do not like <em>David Letterman</em>, so he must be <em>Jose's favorite</em>. This leaves George Burn and Jack Benny
  • Gertrude does not like Jack Benny anymore, so the only one left to be <em>her favorite is George Burn</em>
