<span><span>1.       </span>The restaurant is making 22 ¾ cups of chowder. Each cup of chowder holds 7/8 of a cup.
Then the restaurant charges 2.95 dollars per bowl. Let’s find out how much money will the restaurant earned.
Solutions:
=> 22 ¾ = 22.75 cups of chowder
=> 7/8 = 0.88 cup of chowder it can holds.
Let’s solve to get the correct answer:
=> 22.75 / .88 = 25.85 cups in all.
Then, let’s multiply this with the amount
=> 25.85 * 2.95 = 76.26 dollars.
SO the restaurant earned 76.26 dollars for the chowder.</span>

2(x + 2) + 2 = 2(x + 3) + 1
Maslowich

Answer:

No solution

Step-by-step explanation:

5(x + 4) – x = 4(x + 5) – 1

x = ?

Solution:

5(x+4)−x=4(x+5)−1

Apply Distributive property:

  • (5)(x)+(5)(4)−x=(4)(x)+(4)(5)−1
  • 5x+20−x=4x+20−1

Combine Like Terms:

  • (5x−x)+(20)=(4x)+(20−1)
  • 4x+20=4x+19
  • 4x+20=4x+19

Subtract 4x from both sides:

  • 4x+20−4x=4x+19−4x
  • 20=19

Subtract 20 from both sides:

  • 20−20=19−20
  • 0=−1

There isn't any solutions.
