Answer:

27=3c-3(6-2c)

Open the brackets (multiply 6 and -2c by -3)

27=3c-18+6c

Add 3c and 6c

27=9c-18

Add 18 to both sides

45=9c

Divide by 9

c=5 (45/9)

now to check this just substitute c (5) into the equation

27=(3*5)-18+(6*5)

27=15-18+30

27=30-3

27=27

The note A has a frequency of 1,760 hertz. The note D has a period of 1,175 hertz. Find theratio of A to D to two decimal places

Ratios

Note A has a frequency of

fa=1,760 Hz

Note D has a period of 1,175 hertz

(the previous data should be frequency, not period)

We are required to find the ratio of A to D. Let's call it r:

$r=\frac{1,760^{\prime}}{1,175}$

Dividing: r = 1.4978. Rounding to two decimal places:

r = 1.50

Now to express the answer in integer ratio form, we need to simplify the fraction.

First, we divide by 5 up and down:

$r=\frac{352^{\prime}}{235}$

There are no more common divisors for both numbers, thus the integer ratio form is r = 352/235

Answer:

4 ; 24

Step-by-step explanation:

A.)

Fixed fee, x = $5

Hourly rate, y = $3

Total rent fee, t= $17

Number of rent hours :

$17 = $5 + $3y

17 - 5 = 3y

12 = 3y

y = 12/3

y = 4 hours

B.)

Total Number of tickets , t = 97

Tickets per student, r = 4

Tickets left = 1

Number of students in class:

(97 - 1) / 4

96 /4

= 24 students
