Simplify the expression (2x + 3y) + yusing the properties of operations. Show
your work.

Answers

Answer 1
Answer: (2x + 3y) + y

2x + 4y

The x and y cannot be combined but the y can be added to the 3y. If you ever have a letter that had no number in from of it it just means it’s 1. No need to put it like 1y because some teachers count it wrong. So just keep it as the single letter. Hope this helps good luck!

In dry air at a temperature of 68 F, sound travels at the speed of 767 mph or 1125 ft/sec. How many seconds does it take sound to travel 1 miles (5280 ft) in air?

Answers

Answer:

The answer is 4.69 sec

Step-by-step explanation:

We know time taken = distance / speed

here 1 mile = 5280 feet , so 767 mph = 767x 5280 feet /( 60x60 ) s = 1124.93 feet / sec .

now , time taken Time = (5280)/(1124.933)= 4.69 sec

It will take 4.69 sec for the sound to travel 1 mile or 5280 feet .

Megan borrowed $50,000 at 5% simple interest for 6 years. joseph borrowed $60,000 at 4% simple interest for 8 years. using the formula who will have a greater monthly payment, m, and by how much?

Answers

Answer:

Megan will pay $78 more than Joseph.

Step-by-step explanation:

Formula: Simple Interest = P x R x T

Megan Info

  • Borrowed Money (P)=$50,000
  • Rate of interest (r)=0.05
  • Time (t) = 6 years

Simple interest paid by Megan = 50,000 x 0.05 x 6 = 15000

Total amount paid in 6 years = 50000 + 15000 = $65,000

Monthly payment by Megan (m) = 65000÷72 = $903

Joseph Info

  • Borrowed Money (P)=$60,000
  • Rate of interest (r)=0.04
  • Time (t) = 8 years

Simple interest paid by Magan = 60,000 x 0.04 x 8 = 19200

Total amount paid in 8 years = 60000 + 19200 = $79,200

Monthly payment by Joseph (m) = 79200÷96 = $825

Now we find Difference of monthly payment

⇒Megan - Joseph

⇒ 903-825

⇒ $78

Thus, Megan will pay $78 more than Joseph.

Answer:

Megan will pay approximately $78 more per month.
