Dream Studio offers 5 music lessons for $60. Fox Studio offers 8 music lessons for $72. What is the cost per lesson at each stud
ehidna [41]
Answer:
Dream Studio offers music lessons at $12 per lesson. Fox Studio offers music lessons at $9 per lesson. The better deal here would be Fox Studio. This is because Fox Studio offers cheaper lessons. For eight lessons at Dream Studio it costs $96, where as eight lessons at Fox Studio costs only $72.


Explanation:
Step 1 - Find the cost per lesson at Dream Studio

60 / 5 = 12

So, $12 per music lesson at Dream Studio.

Step 2 - Find the cost per lesson at Fox Studio

72 / 8 = 9

So, $9 per music lesson at Fox Studio.

Step 3 - Find out which offers a better deal

•Dream Studio = $96 for eight music lessons
• Fox Studio = $72 for eight music lessons

Some History teachers at Riverside High School are purchasing tickets for students and their adult chaperones to go on a field t
Mariana [72]

Answer:

Cost of student ticket =  $7

Cost of Adult ticket = $17

Step-by-step explanation:

Let cost of student ticket = x

Cost of Adult ticket = y

Making expressions from statements

Mrs. Levin bought 27 student tickets and 25 adult tickets, which cost a total of $614. 27x+25y=614

Mr. Lawson spent $733, getting 27 student tickets and 32 adult tickets. 27x+32y=733

Now solving these equations to find values of x and y

Let

27x+25y=614--eq(1)\\27x+32y=733--eq(2)

Subtracting both equations

27x+25y=614\\27x+32y=733\\-\:\:\:-\:\:\:\:\:\:\:\:\:\:\:\:-\\-------\\-7y=-119\\y=\frac{-119}{-7}\\y=17

So, we get value of y = 17

Now, finding value of x, by putting value of y in eq(1)

27x+25y=614\\Put\:y=17\\27x+25(17)=614\\27x+425=614\\27x=614-425\\27x=189\\x=\frac{189}{27}\\x=7

So, we get value of x = 7

Cost of student ticket = x = $7

Cost of Adult ticket = y = $17

What is the value of x, when x2 + 5 = 21?
djverab [1.8K]

Hey there!

  • \bold{x^2+5=21}
  • <em>Firstly, subtract by the number \bold{5}  on each of your sides</em>
  • \bold{x^2+5-5=21-5}
  • \bold{Cancel:5-5} because it gives us the result of \bold{1}
  • \bold{Keep:21-5}  because it equals: \bold{16}
  • \bold{x^2=16}
  • <em>Nextly, we have to take our square root </em>
  • \bold{x=}±\bold{\sqrt{16}}
  • <em>Solve the square root and you have found your answer</em>
  • <em>\boxed{\boxed{\bold{Answer:x=4[or]x=-4}}} \bold{\checkmark}</em>

Good luck on your assignment and enjoy your day!
