For this case we have the following equation:

$4x + 12 = 48$

Where the variable "x" represents the cost of a performance ticket.

Clear "x" of the equation to know the cost of a ticket.

Subtracting 12 on both sides of the equation:

$4x = 48-12\\4x = 36$

Dividing between 4 on both sides of the equation:

$x = \frac {36} {4}\\x = 9$

So, the cost of a ticket is $ 9.00

Answer:

$9.00

Step-by-step explanation:

4x + 12 = 48 - First, subtract 12 from each side of the equation.

4x = 36 - Then, divide each side by 4 to get x by itself.

x = 9 - After dividing by 4, we are left with x = 9, so 1 ticket costs

$9.00

Alonzo needs 5/6 of a yard of fabric to cover a chair. He plans to cover 8 chairs. What is the least amount of fabric he will ne

stepan [7]

You have to do 5/6 of 8
first 8÷6=1.3 (or remainder 3)
1.3×5=6.5
So that means Alonzo will need 6.5m at least amount of fabric.
Hope this helped! :)

Step-by-step explanation:

yuson has to finish am total of 30 hours in community service

she does 2 hours each day

in x days, hour of service done=2x

after x days hours of service left=30-2x

therefore the linear equation representing the hours yuson has left after x days is:

30-2x

Question 22 A city has a population of people. Suppose that each year the population grows by . What will the population be afte

Alexeev081 [22]

Answer:

911,690.

Step-by-step explanation:

Please consider the complete question.

A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.

We will use exponential growth formula to solve our given problem.

$y=a\cdot (1+r)^x$ , where,

y = Final value,

a = Initial value,

r = Growth rate in decimal form,

$6.75\%=\frac{6.75}{100}=0.0675$

$y=390,000\cdot (1+0.0675)^x$

$y=390,000\cdot (1.0675)^x$

To find the population after 13 years, we will substitute $x=13$ in population growth equation as:

$y=390,000\cdot (1.0675)^{13}$

$y=390,000\cdot 2.3376661492982871$

$y=911689.798226331969$

Upon rounding to nearest whole number, we will get:

$y\approx 911,690$

Therefore, the population of the city after 13 years would be 911,690.
