Mathematics

Rudik [331]3 years ago

Step 1: Add the two equations.

Step 2: Solve for x.

Step 3: To find the y-value, substitute in 3 for x in one of the equations.

Step 4: Solve for y.

Step 5: Identify the solution as an ordered pair.

What if adding or subtracting does not eliminate a variable? Example. 3x – y = 8. x + 2y = 5.

maria [59]

Answer:

  • y = 2/3x

Step-by-step explanation:

<u>Reading rate is y pages per x minutes and proportional relationship formula is:</u>

  • y = kx

<u>The coefficient is:</u>

  • k = y/x

<u>Let's verify if the given numbers fit into the same relationship:</u>

  • 12/18 = 2/3
  • 8/12 = 2/3
  • 20/30 = 2/3

We confirm all same and it means k = 2/3

<u>Required equation is:</u>

  • y = 2/3x

This represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages

Tim installs 50 square feet of his floor in 45 minutes. At this rate, how long does it
spin [16.1K]

Answer:

9 hrs and 10 mins

Step-by-step explanation:

We can convert this into a proportion. 50/45 = x/495. Cross-multiply to get 45x = 50*495. Divide both sides by 45 to get x = 50*11 = 550 minutes or 9 hrs and 10 mins
