Answer:

50

Step-by-step explanation:

The translation of the question is as shown;

First note that the original number is 35

The sum of 35 and one-fifth part of itself .

= 35 + 1/5(35)

= 35+7

= 42 ... A

sum of one-seventh part of itself and 3 will be;

= 1/7(35) + 3

= 5+3

= 8... B

Adding A and B together wiill give us the final result

A+B = 42+8

A+B = 50

The sum of 35 and one-fifth part of itself added to the sum of one-seventh

part of itself and 3 is therefore equivalent to 50

anzhelika [568]

Answer:

6\ polyphonic\ ringtones  and 1\ standard\ ringtone

Step-by-step explanation:

Let

x -----> the number of polyphonic ringtones

y ----> the number of standard ringtones

we know that

x+y=7

x=7-y -----> equation A

3.25x+1.50y=21 -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for y

3.25(7-y)+1.50y=21

22.75-3.25y+1.50y=21

3.25y-1.50y=22.75-21

1.75y=1.75

y=1\ standard\ ringtones

Find the value of x

x=7-1=6\ polyphonic\ ringtones

The cash price of a television is $580.
Drupady [299]

Answer:

n=25% or 0.25

Step-by-step explanation:

865= 580(n%)+ 6(120)

865= 580 (n%) +720

865-720= 145

145= 580(n%)

divide both by 580, you get 0.25=n%

IN A CLASS OF 30 STUDENTS 13 OF THEM ARE BOYS WHAT PERCENTAGE ARE GIRLS?
mestny [16]
Class of students - number of students that are boys = numbers of students that are girls

30 - 13 = 17

To change the number of students that are girls into percentage...

17/1 * 1/100 = 17/100

17/100 in a % form = 17%

The percentage of girls in the class is 17%
