Keith_Richards [23]

The number of hot dogs, x is 36 and hamburgers, y is 5 were sold

Step-by-step explanation:

Carlos ran a concession stand last Saturday and made $63.90 from

a total of 41 hot dogs and hamburgers. Each hot dog sold for $1.40

and each hamburger sold for $2.70

1. The number of hot dogs is x, and hamburgers is y

2. He made $63.90 from a total of 41 hot dogs and hamburgers

3. Each hot dog sold for $1.40 and each hamburger sold for $2.70

We need to find the number of hot dogs and hamburgers, that were sold

∵ The number of hot dogs is x, and hamburgers is y

∵ He sold 41 hot dogs and hamburgers

∴ x + y = 41 ⇒ (1)

∵ Each hot dog sold for $1.40 and each hamburger sold for $2.70

∵ He sold x hot dogs and y hamburgers

∵ He made $63.90 from sold them

∴ 1.4 x + 2.7 y = 63.9 ⇒ (2)

Let Us solve the system of equations to find x and y

Multiply equation (1) by -2.7 to eliminate y

∵ (-2.7)x + (-2.7)y = (-2.7)(41)

∴ -2.7 x - 2.7 y = -110.7 ⇒ (3)

- Add equations (2) and (3)

∴ -1.3 x = -46.8

- Divide both sides by -1.3

∴ x = 36

Substitute the value of x in equation (1) to find y

∵ x + y = 41 ⇒ (1)

∴ 36 + y = 41

- Subtract 36 from both sides

∴ y = 5

The number of hot dogs, x is 36 and hamburgers, y is 5 were sold

. In Problem 2, how many lateral faces would there be if the base had
Alla [95]

The number of lateral faces for a hexagonal prism or pyramid is 6.

<h3>What is a prism?</h3>

A prism is a three dimensional figure consisting of pair of opposite bases and lateral faces which are parallelogram.

Given that the base off the prism has two sides of length 3 inches and four sides of length 2 inches. Hence the base is hexagonal. The lateral faces would be 6.

The number of lateral faces for a hexagonal prism or pyramid is 6.

  • Left to Right  

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Factoring
  • Quadratic Formula: \displaystyle x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

<u>Algebra II</u>

  • Imaginary Numbers: √-1 = i

Step-by-step explanation:

<u>Step 1: Define</u>

x² + 2x = -2

<u>Step 2: Identify Variables</u>

  1. Rewrite Quadratic in Standard Form [Addition Property of Equality]:        x² + 2x + 2 = 0
  2. Break up Quadratic:                                                                                        a = 1, b = 2, c = 2

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [Quadratic Formula]:                                                \displaystyle x=\frac{-2 \pm \sqrt{2^2-4(1)(2)}}{2(1)}
  2. [√Radical] Evaluate exponents:                                                                     \displaystyle x=\frac{-2 \pm \sqrt{4-4(1)(2)}}{2(1)}
  3. Multiply:                                                                                                           \displaystyle x=\frac{-2 \pm \sqrt{4-8}}{2}
  4. [√Radical] Subtract:                                                                                        \displaystyle x=\frac{-2 \pm \sqrt{-4}}{2}
  5. [√Radical] Factor:                                                                                        \displaystyle x=\frac{-2 \pm \sqrt{-1}\sqrt{4}}{2}
  6. [√Radicals] Simplify:                                                                                       \displaystyle x=\frac{-2 \pm 2i}{2}
  7. Factor:                                                                                                             \displaystyle x=\frac{2(-1 \pm i)}{2}
  8. Divide:                                                                                                             \displaystyle x = -1 \pm i
