Imagine your friend's cousin writes a rebuttal argument to her claim in favor of teens owning smartphones. Read his argument exc

erpt and answer the question that follows: Smartphone ownership among teens is certainly on the rise. Yet there is reason for caution. Teens are showing signs of smartphone addiction. A survey by TextPlus found that half of teens "couldn't live without their mobile devices for a week, while 36 percent said they weren't able to go 10 minutes without checking their phones." All this time on the devices creates more chances for problems. Smartphones and social media have been linked to serious cases of cyber bullying. Some students have been hurt or worse. A school superintendent in California, J. Thomas Morton, sent a letter to parents. He asked them to monitor their teens' use of all electronic devices, as cyber bullying incidents are on the rise. Which of the following is true about this argument excerpt? It is respectful in tone to the audience and supports its claim with specific, credible evidence. It contains specific, credible evidence but uses a disrespectful tone that should be edited. It fails to support its claim with specific, credible evidence and uses a disrespectful tone. It uses a respectful tone but needs specific, credible evidence to support the claim.

Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be
sdas [7]

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks =2\times 3=6

Marks obtained by Mia = Total marks - Deducted marks

                                      =50-6

                                     =44

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks =2\times x=2x

Marks obtained by Mia = Total marks - Deducted marks

                                      =50-2x

So, Mia's test score is (50-2x) if she got x questions wrong.

jar contains 51 coins which are either quarters or nickels. total value of jar is 5.15. how many of each type of coin do they ha
docker41 [41]
I believe there are 20 quarters and 3 nickels.....

Total value of the jar is $5.15.....

Quarters are worth 25 cents
And nickels are worth 5 cents.

First you know that there are 4 quarters in a dollar.
 You have 5 dollars so you do 4 x 5 = 20

So five dollars ($5.00) is 20 quarters.
And you still have 15 cents left.

Because quarters are 25 cents the rest are nickels.

Nickels are worth 5 cents so you'd do 5 x 3 = 15.

15 cents!

Add all this together and get $5.15.

So your answer is 

There are 20 quarters and 3 nickels in the jar.
