Answer:

7 females, 24 males

Step-by-step explanation:

I solved it by using this equation:

2x + 17 = 31

then, i subtracted 17 on both sides:

2x=14

then divide by 2 on both sides:

x=7

then I added 7 to 17 to find the number of males:

7+17= 24

<h2><u>Answer:</u></h2>

More classmates liked hip-hop than relatives.

<h2><u>Step-by-step explanation:</u></h2>
  • First, turn the percentages into decimals by dividing them by 100:

        62 ÷ 100 = 0.62

        70 ÷ 100 = 0.7

  • Then, multiply the amount of people by the decimals towork out how many people like hip-hop:        
  • CLASSMATES = 80 × 0.62 = 49.6 (0r 50 when rounded tp the nearest person)
  • RELATIVES = 60 × 0.7 = 42 people

  • As 50 is more than 42, this shows that <u>more classmates liked hip-hop than relatives</u>

What is 7/12+5/6?<br><br> Add the fractions, please
olya-2409 [2.1K]

Answer:

1 5/12

Step-by-step explanation:

first we have to convert the denominator(bottom number) to 12

6x2=12

Now we have to multiple 2 to the numerator(top number)

since we have to do the same to the top and bottom

5x2=10

now we add the fractions

7/12+ 10/12=17/12

now we simplify the fraction

17/12= 1 5/12

hopefully you understand how to do it.

Have a good day:)
