The sum of three consecutive is 267. What is the largest integer

1 answer:

4 0

Consecutive means in order. So let's call the first integer x. The next number in line would be x+1 and the largest integer would be x+2. Let's prove that so you're not confused. If x is 3, then x+1 is 4 (next in line), and x+2 is 5 next after that. See? So if we add all those together we set them equal to 267 and solve for x: x + x+1 + x+2 = 267. Combining like terms gives us 3x + 3 = 267 and 3x = 264. Now dividing both sides by 3 we get that x = 88. That's the smallest integer; the largest is found by adding 88 + 2 which is 90. So that means that the numbers are 88, 89, 90, and that adding them up = 267. Let's check that now: 88+89+90=267 so we're good.

The price of a notebook was

Pie

Old price: p1 = $ 3.90;

New price: p2 = $ 3.40.

The percentual decrease is given by

d(%) = [ (p2 - p1) / p1 ] * 100 %

d(%) = [ (3.40 - 3.90) / 3.90 ] * 100 %

d(%) = [ - 0.50 / 3.90 ] * 100 %

d(%) = - 0.128 * 100 %

d(%) = - 12.8 % (approximately)

So the price fell 12.8 % approximately.

I hope this helps. =)

I rlly need help solving

Alchen [17]

Answer:

x=20

Step-by-step explanation:

The line is a straight line, which is 180 degrees

x+100+3x = 180

Combine like terms

100+4x = 180

Subtract 100 from each side

100+4x-100=180-100

4x=80

Divide by 4

4x/4 = 80/4

x=20

Watch day about 75,000 people visit Paris, France. Use commutative property to write two equivalent expressions that could be us

Studentka2010 [4]

Answer:

$5\times 75,000$ and $75,000\times 5$

Step-by-step explanation:

We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period .

To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:

$\text{Number of people that visits over a 5-day period}=75,000\times 5$

Commutative property of multiplication states that we can multiply numbers in any order.

Upon switching the order while multiplying, we will get:

$\text{Number of people that visits over a 5-day period}=5\times 75,000$

Therefore, our required equivalent expressions would be $5\times 75,000$ and $75,000\times 5$ .
