Which graph shows the solution to the following inequality?

Answers

Answer 1

Answer:

Answer:

We are given a inequality with the equality sign in terms of variable 'r' as:

$-2r+3\geq 19$

Now we find the solution of the following inequality by solving for 'r'.

We subtract 3 from both side of the inequality to obtain:

$-2r+3-3\geq 19-3\n\n-2r\geq 16$

Now we multiply both side by "-1" to obtain:

$2r\leq -16$

Now on dividing both side of the inequality by 2 we obtain:

$r\leq -8$

Hence, the solution of the inequality are the set of all the points on the number line which are less than equal to -8.

i.e. the shaded region is to the left of -8 and closed circle at -8.

i.e. the solution is: (-∞,-8].

Number 2 graph is the correct graph of the solution.

Charlotte bought 16 songs for her MP3 player. Three-fourths of the songs are classical songs. How many of the songs are classical songs?

Answers

I think 8 are classical songs

12 songs because if you look at the problem there is the word “of”. The word of means multiply, so if you make 16 into fraction that is 61/1 and multiply that my 34 the word problem is,16/1 x 3/4= 48/4 and 48 over 4 is equal to 12 and that is 12 songs.

the distance between Columbus Ohio and New York City is about 560 miles how many hours would it take the train to travel between cities

Answers

The number of hours the train took to travel between the two cities is 2.09 hours.

Given that,

The distance between Columbus, Ohio, and New York City is about 560 miles.

And, The train travels 268 miles an hour.

We need to find out how many hours would it take the train to travel between the two cities.

Here, the train speed is,

= 268 miles per hour

And, the distance between the two cities.

= 560 miles

We have,

268 miles = 1 hour

Multiply both sides by 560

560 x 268 miles = 560 x 1 hour

Divide both sides by 268

560 miles = (560/268) x 1 hour

560 miles = 2.09 hours

Hence, the train will take 2.09 hours to travel 560 miles,

The complete question is,

The distance between Columbus, Ohio, and New York City is about 560 miles how many hours would it take the train to travel between the two cities The train travels 268 miles an hour.

2144 miles in 8 hours. In 1 hour = 2144 / 8 = miles in 1 hour and that = 268

I have to answer this but I dont know how can you help me 5x-2= -7

what is x??

Answers

Hi there!

Answer:

x=-1

Step-by-step explanation:

Distributive property: ⇒ a(b+c)=ab+ac

5x-2=-7

add 2 both sides of an equation.

5x-2+-7+2

simplify.

5x=-5

divide by 5 both sides of an equation.

5x/5=-5/5

simplify

-5/5=-1

x=-1

What is 7/12 minus 4/12

Answers

Because these two fractions already have a common denominator (12=12), all we need to do to solve this problem is subtract the numerators.

7-4=3. Therefore, because there is a common denominator and that doesn't change, 7/12 - 4/12 = 3/12

The answer for 7/12-4/12 is 1/4!
