Answer:
D:21
Step-by-step explanation:
Use the vertical angles equation.
4x + 13 = 5x - 8
Subtract 4x from 5x.
5x - 4x = x
13 = x - 8
Add 8 on both dies.
13 + 8 = 21
x = 21
JKLM has x that equals 21.

Mrs. Hart went to get her nails done at the salon. The cost was $35.00. What is the total amount if tax is 6% and she wants to leave a 18% tip?
A. $24.00
B. $43.40
C. $8.40
D. $59.00
Answer:
B) $43.40
Step-by-step explanation:
For the tax, 6% of 35 = 2.1
So with tax = $35 + 2.1 = $37.1
18% tip
So, 18% of 35 = 6.3
So we are gonna add all the costs together = 37.1 + 6.3 = $43.40
Answer:
Answer:
B) $43.40
Step-by-step explanation:
For the tax, 6% of 35 = 2.1
So with tax = $35 + 2.1 = $37.1
18% tip
So, 18% of 35 = 6.3
So we are gonna add all the costs together = 37.1 + 6.3 = $43.40

Sarah buys a shirt on sale at Jersey's. The original price was $28, but the shirt is on sale for 30% off. If there is a 5% sale tax, how much did Sarah pay for the shirt?
Answer:
$20.58
Step-by-step explanation:
28 x 0.30 = 8.4
28 - 8.4 = 19.6
19.6 x 0.05 = 0.98
19.6 + 0.98 = 20.58

In a fruit cocktail, for every 25 ml of orange juice you need 30 ml of apple juice and 45 ml of coconut milk. What proportion of the cocktail is apple juice?
Give your answer as a fraction in its simplest form.
Answer:
The proportion of apple juice
[tex]p = \frac{3}{10} = 0.3[/tex]
Step-by-step explanation:
Given that fruit cocktail, for every 25ml of orange juice
Given that 30ml of apple juice
Given that 45ml of coconut milk
we need to find the proportion of apple juice
The proportion of apple juice
[tex]p = \frac{x^{-} }{n} \\ = \frac{30}{100} \\[/tex]
[tex]p = \frac{3}{10}[/tex]
The proportion of apple juice [tex]p = \frac{3}{10}[/tex]
Is x = 6 a solution to the equation x + 13 = 18?
Answer:
No, the answer is 5
Answer: No the solution is 5
Step-by-step explanation:
When you substitute x with 6 you get 6+13= 18.
Obviously 6+13 is not 18 so this means that 6 is not a solution.

Write an expression to represent the perimeter of a rectangle with the length of x -4 and width of 2x +8.
Answer:
2(x-4) + 2(2x+8) OR long way (x-4) + (x-4) + (2x+8) + (2x+8)
Step-by-step explanation:
2(x-4) represents the (x-4) + (x-4) in the longer version since for perimeter you add the sides. Same thing for the other side, 2(2x+8) represents (2x+8) + (2x+8).
Not sure if you need the expression solved but here:
[tex]2(x-4) + 2(2x+8)\\(2x-8) + (4x+16)\\=6x+8[/tex]
To get from first line to second, use distributive property. To get from second to third line, combine like terms.
The perimeter of a rectangle with the length of (x - 4) and width of
(2x +8) will be (6x + 8).
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
The length of rectangle = x - 4
The width of rectangle = 2x + 8
Now,
Since, The length of rectangle = x - 4
The width of rectangle = 2x + 8
We know that;
The perimeter of rectangle = 2 (Length + Width)
⇒ The perimeter of rectangle = 2 (x - 4 + 2x + 8)
⇒ The perimeter of rectangle = 2 (3x + 4)
⇒ The perimeter of rectangle = (6x + 8)

A falling object travels a distance given by the formula d=3t+5t2, where d is measured in feet and t is measured in seconds. How many seconds will it take for the object to travel 84 feet?
Answer:
Approximately 3.81 seconds
Step-by-step explanation:
d = 3t + 5t²
d = 84
84 = 3t + 5t²
3t + 5t² - 84 = 0
5t² + 3t - 84 = 0
5(t² + 3/5t - 84/5) = 0
5(((t + 3/10)² - 9/100) - 84/5) = 0
5((t + 3/10)² - 9/100 - 84/5) = 0
5((t + 3/10)² - 9/100 - 1680/100) = 0
5((t + 3/10)² - 1689/100) = 0
5(t + 3/10)² - 1689/20 = 0
5(t + 3/10)² = 1689/20
(t + 3/10)² = 1689/100
t + 3/10 = ±√(1689)/10
t = -3/10 ± √(1689)/10
t = -3/10 ± ≈41.1/10
t = -3/10 ± ≈4.11
t ≈ -0.3 ± 4.11
t [can only be positive] ≈ 4.11 - 0.3
t ≈ 3.81

Is there a value for x for which the perimeters are equal?
What is the linear equations?
Answer:
Hope it works for u
Step-by-step explanation:
As we have given two shapes bathroom
square and rectangle
Parameter of square= sum of all the sides ( : In square all sides are equal
Parameter of square= 4*L = 4*(x+3) (:L=x+3
similarly,
In rectangle opposites sides are equal hence
Perimeter of rectangle= 2*length+2*width ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1 hope this is equal to the width of ur question otherwise do the calculation by ur self).
Perimeter of rectangle= 2*(x+4)+2(x+1)
so now we have to find the value of "x" for which both perimeter are equal, so
perimeter of square= perimeter of rectangle
4*(x+3)=2*(x+4)+2(x+1) we can also write as
2(x+3)+2(x+3)=2(x+4)+2(x+1)This is the linear equation requirednow to find value of "x"simplify both sides, we get4x+12=4x+100≠2 so that not true and also there is no value of "x"for which both parameters become equal
so from my side "b" option is correctPlease brain-list it if u find it help-full it requires effort!
Answer: B option is correct. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Determine whether each equation represents a linear or nonlinear function.
Equation Linear Non - linear
y = 2x³ + 1 No Yes
y = 3x Yes No
y = x/5 Yes No
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y = 2x³ + 1
For x = 1, 2, 3,
y = 2 + 1 = 3
y = 2 x 2³ + 1 = 2 x 8 + 1 = 17
y = 2 x 3³ + 1 = 2 x 27 + 1 = 54 + 1 = 55
The rate of change.
Between 3 and 17 = 17 - 3 = 14
Between 17 and 55= 55 - 17 = 38
This means the equation is not linear.
y = 3x
For x = 1, 2, 3,
y = 3 x 1 = 3
y = 3 x 2 = 6
y = 3 x 3 = 9
The rate of change.
Between 3 and 6 = 6 - 3 = 3
Between 6 and 9 = 9 - 6 = 3
This means the equation is linear.
y = x/5
For x = 1, 2, 3,
y = 1/5
y = 2/5
y = 3/5
The rate of change.
Between 1/5 and 2/5 = 2/5 - 1/5 = 1/5
Between 2/5 and 3/5= 3/5 - 2/5 = 1/5
This means the equation is linear.
Thus,
y = 2x³ + 1 is a linear equation.
y = 3x is not a linear equation.
y = x/5 is a linear equation.

Which shows all the values of x that make the rational expression 2x^2-72/5x^2-245 underlined
Answer:
7 and -7
Step-by-step explanation:
Correct question
Which shows all the values of x that make the rational expression 2x^2-72/5x^2-245 undefined
For the expression to be undefined, the denominator must be equal to zero
Hence 5x² - 245 =0
Add 245 to both sides
5x²-245+245 = 0+245
5x² = 245
x² = 245/5
x² = 49
x = ±√49
x =7 and -7
Hence the values of x that will make the function undefined are 7 and -7
