Answer:
x=16
Step-by-step explanation:
1/2 ( x - 4 ) = 1/3 ( x + 2)
distribute both sides
1 /2 (x−4)= 1/ 3 (x+2)
( 1 /2 )(x) + ( 1/ 2 )(−4) =( 1 /3 ) (x)+( 1/3 )(2)(Distribute)
1 /2 x+−2= 1 /3 x+ 2 /3
1 /2 x+−2= 1 /3 x+ 2 /3
Step 2: Subtract 1/3x from both sides.
1/2x -2 -1/3 x
x= 1 /3 x + 2/3 − 1/ 3 x
1 /6 x−2= 2/ 3
Step 3: Add 2 to both sides.
1 /6 x −2+2= 2/ 3 +2
1 /6 x = 8 /3
Step 4: Multiply both sides by 6.
6*( 1/6 x) =6*( 8 /3 )
x=16

there were 252 people at the concert . If 90% of the seats were filled, how many seats are in the auditorium?
Answer:
280 seats total
Step-by-step explanation:
90/100 = 252/x
To find x, cross multiply.
90x = 25,200
Divide both sides by 90 to get the variable alone.
x = 280 seats

Find the equation of the line that is:
Parallel to 2x – 4y = 8 and has the same y-intercept as 5x + y -10 = 0
Answer:
y = 1/2 x + 10
Step-by-step explanation:
The equation should be in format
y = mx + b with m being the slope and b being the y-intercept.
The y-intercept of 5x + y - 10 = 0 is the same as the y-intercept of the unknown equation. The y-intercept of 5x + y - 10 = 0 is 10, so now our unknown equation is y = mx + 10.
Two parallel lines have the same slope but different y-intercepts, so we just need the slope of 2x - 4y = 8, which in the y = mx + b form, is y = 1/2 x - 2. Now, we just copy the slope of y = x/2 - 2 to the slope of the unknown equation, which results in y = 1/2 x + 10.
In conclusion, the unknown equation that is parallel to 2x - 4y = 8 and shares the same y-intercept as 5x + y - 10 = 0 is y = 1/2 x + 10

A store has x number of shirts. Each shirt was sold for $16, but the last dozen was sold on sale for $14 each. When all shirts were sold, the store gained $616. Find the number of shirts sold at the regular price.
Answer:
28 shirts
Step-by-step explanation:
Let's see what we are given.
there are x amount of shirts ($616 total)
there are 12 in a dozen
the regular shirts are $16
the last 12 shirts are $14
Lets make an equation.
616= 14(12) + 16x
616=168+16x
448=16x
x=28

⅜ of the animals at the zoo equals to 600. 40% of all the animals at the
zoo were fed. How many animals were still to be fed?
Answer:
960
Step-by-step explanation:
3/8*total number of animals = 600
total number of animals = 8/3 * 600 = 1600
number of animals fed = 40/100 * 1600 = 640
animals still to be fed = 1600 - 640 = 960

3. The price of a pair of shoes is $64.00 plus 9% sales tax. What is the sales tax on this pair of shoes in dollars and cents? A. $5.76 B. $57.60 $69.716) D. $78.00
Step-by-step explanation:
To figure out this answer, you need to figure out how much 9% is in $64.00
? 9
------- = --------
64 100
Now to solve this you have to multiply diagonally and divide the neighbor
(let me explain)
basically in this case, you would multiply 64 and 9, then divide by 100
64 * 9 = 576
576 / 100 = $5.76
In short: your answer is 'A' $5.76

An employee earns a gross pay of $1,200.00 per week. The employee's net pay is $850.00. The employee's voluntary 401(k) contribution is $50.00 per month.
Answer:
$300 was deducted from tax. The tax rate is 26.1%
Step-by-step explanation:
An employee earns a gross pay of $1,200.00 per week. The employee’s net pay is $850.00. The employee’s voluntary 401(k) contribution is $50.00 per month.
There was blank deducted for taxes. The tax rate is blank
Solution:
Contributions that are made for retirement such as 401(k) contribution plans are made on a pretax basis. This means that they are removed from your taxable income, thereby reducing the tax.
Gross pay = $1200
Taxable income = Gross pay - 401(k) contribution
Taxable income = $1200 - $50 = $1150
Net pay = $850
Tax = Taxable income - Net pay
Tax = $1150 - $850
Tax = $300
Tax rate = (Tax / taxable income) * 100%
Tax rate = ($300 / $1150) * 100% = 26.1%
A sporting goods store bought a ski set at a cost of $432. Later, the ski set was marked down 10% from its selling price and then marked down another 20%. The total markdown is the greatest possible markdown without the store losing money. Find the original selling price.
Answer:
The original selling price of the ski set is $600
Step-by-step explanation:
The cost price of the ski set = $432
The first percentage mark down of the ski set = 10% from its selling price
The first percentage mark down of the ski set = 20% from its selling price
Let x represent the original selling price of the ski set at the sporting goods store, we are given;
80/100 × (90/100 × x) = The cost price of the ski set
Therefore, we have;
80/100 × (90/100 × x) = 432
0.72 × x = 432
x = 432/0.72 = 600
Therefore, the original selling price of the ski set, x = $600

Use what you know about triangles and angle relationships to determine the value of x and y in this isosceles triangle.
(Note: use whole numbers only, do not type the degree
symbol or the word)
Answer:
x = 13
y = 7
Step-by-step explanation:
✔️Recall that sum of the interior angles of a ∆ = 180°
Therefore:
(3x - 3) + (4x + 20) + (7x - 19) = 180° (sum of ∆)
Solve for x
3x - 3 + 4x + 20 + 7x - 19 = 180
14x - 2 = 180
Add 2 to both sides
14x = 182
Divide both sides by 14
✅x = 13
✔️Recall also that an isosceles has two equal sides, therefore:
8y - 7 = 5x - 16
Plug in the value of x
8y - 7 = 5(13) - 16
8y - 7 = 65 - 16
8y - 7 = 49
Add 7 to both sides
8y = 56
Divide both sides by 8
✍️y = 7
Question: Tell whether each function is linear or non-linear.
Choices:
A. Function A is non-linear and Function B is non-linear.
B. Function A is linear and Function B is non-linear.
C. Function A is linear and Function B is linear.
D. Function A is non-linear and Function B is linear.
Just to avoid some confusion: the first picture is a graph of function A, and the second picture is a graph of function B.
Answer:
D. Function A is non-linear and Function B is linear.
Step-by-step explanation:
A good way to find out if a function is linear is by graphing it. If you graph it and it is a straight line, then it is linear.
So, let's graph the given points from the table of Function A and see if it forms a straight line. When you connect the dots, it's not straight, so Function A is non-linear.
Now let's look at function B. We can graph that too with the given information from the equation - the slope is -1 and the y-intercept is 5. (If you are a bit confused on how to graph it, don't hesitate to ask!) It does form a straight line, so Function B is linear.
The solution is Option D.
Function A is non-linear and Function B is linear.
What is Linear Equation in 2 variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Given data ,
Let the first equation be A
Let the second equation be B
where
The function A is represented by y = x³
The function B is represented by y = -x + 5
Now ,
We can see that the linear equation A is of the form y = x³ , and this is a cubic relation and it is a non linear graph
The function B is a linear equation of the form y = mx + c , which is the linear equation for a line with slope -1
So , the function B y = -x + 5 is linear
Hence , the Function A is non-linear and Function B is linear.
