Answer:
the answer is 1/2
Step-by-step explanation:
Step 1 of 2: Convert decimal to fraction.
Convert decimal to fraction
0.5 = 5/ 10
Step 2 of 2: Simplify, sub-step a: Reduce fraction to lowest terms.
Reduce fraction to lowest terms
5 / 10
then divide ( 5 ÷ 5 ) over ( 10 ÷ 5 )

A women spent two thirds of her money. She lost two thirds of the remainder and then had $4 left. How much money did she start with?
Answer: She originally had $36
Step-by-step explanation: 4x3 = 12, then multiply that by 3, and you get 36. Because to find the whole you need to multiply each number by three.
Evaluate the expression |- 15| + | -7|
Answer:
Step-by-step explanation:
The lines in between the numbers are called absolute value bars. Whenever you see numbers that have absolute value bars, know that the numbers become positive.
Therefore,
|-15| = 15
|-7| = 7
Now we just add,
15+7=22
Final answer = 22

given function of f(x) = 2x - 1 and fg(x) = 10x + 3, find the function of g(x)
Answer:
The function of g(x) = 5x + 2
Step-by-step explanation:
Let us use the composite function to solve the question
∵ f(x) = 2x - 1
∵ f(g(x)) = 10x + 3
→ f(g(x)) means substitute x in f(x) by g(x)
∴ f(g(x)) = 2[g(x)] - 1
→ Equate the two right sides of f(g(x))
∴ 2[g(x)] - 1 = 10x + 3
→ Add 1 to both sides
∴ 2[g(x)] - 1 + 1 = 10x + 3 + 1
∴ 2[g(x)] = 10x + 4
→ Divide each term into both sides by 2
∵ [tex]\frac{2[g(x)]}{2}[/tex] = [tex]\frac{10x}{2}[/tex] + [tex]\frac{4}{2}[/tex]
∴ g(x) = 5x + 2
∴ The function of g(x) = 5x + 2
Olivia Earns $14 per hour at her job and receives a weekly bonus $100. Her total pay for the week of X hours is given by f(x)=100+14x. What is the reasonable domain and range?
Answer:
Step-by-step explanation:
Given the total pay for the week of X hours given by f(x)=100+14x, the domain of the function is the value of the input variable x for which the function exists. Since her to total week cannnot be negative, hence the value of x for which the function occurs is on all positive integers. This is represented according to the set notation;
Domain = [0, ∞)
The range of the function is the value of the output variable f(x) for all vaues of x for which the function occurs. Snce the minimum value of x is 0, the minimum value of the function will be at f(0);
f(0) = 100 + 14(0)
f(0) = 100 + 0
f(0) = 100
Hence the range of the function will be expressed as;
Range = [100, ∞)

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
-x + 5y = -4
4x + 3y = 16
Step 2: Rewrite systems
x = 5y + 4
4x + 3y = 16
Step 3: Solve for y
Substitute in x: 4(5y + 4) + 3y = 16Distribute 4: 20y + 16 + 3y = 16Combine like terms: 23y + 16 = 16Subtract 16 on both sides: 23y = 0Divide 23 on both sides: y = 0Step 4: Solve for x
Define: 4x + 3y = 16Substitute in y: 4x + 3(0) = 16Multiply: 4x = 16Isolate x: x = 4And we have our final answer!

Jennifer bought some tulips, lilies, and roses to make bouquets. She bought the same number of tulips as lilies. She bought three more roses than tulips and lilies combined. She paid 18 cents for each tulip. The lilies were 27 cents per flower, and the roses cost 55 cents each. How many of each kind of flower did Jennifer buy if she paid $17.15 in all?
Answer:
z = 18.5
y = 15.5
x = 15.5
Step-by-step explanation:
Let
tulips = x
lilies = y
roses = z
x = y
z= x + 3 or y + 3
The equation is
0.18x + 0.27y + 0.55z = 17.15
Substitute x = y and z = y + 3 into the equation
0.18y + 0.27y + 0.55(y + 3) = 17.15
0.18y + 0.27y + 0.55y + 1.65 = 17.15
y = 17.15 - 1.65
= 15.5
x = y
x = 15.5
z = x + 3
= 15.5 + 3
= 18.5
Therefore,
z = 18.5
y = 15.5
x = 15.5

The two complex or imaginary roots [tex]x = i\sqrt{5}[/tex] and [tex]x = -i\sqrt{5}[/tex] have multiplicity 2.The two real roots x = 5 and x = -5 have multiplicity 3The root x = 8 has multiplicity 4======================================================
Explanation:
We'll use the zero product property to solve.
[tex]3(x^2+5)^2(x^2-25)^3(x-8)^4 = 0\\\\(x^2+5)^2=0 \text{ or } (x^2-25)^3=0 \text{ or } (x-8)^4 = 0\\\\x^2+5=0 \text{ or } x^2-25=0 \text{ or } x-8 = 0\\\\x^2=-5 \text{ or } x^2=25 \text{ or } x = 8\\\\x=\pm\sqrt{-5} \text{ or } x=\pm\sqrt{25} \text{ or } x = 8\\\\x=\pm i\sqrt{5} \text{ or } x=\pm 5 \text{ or } x = 8\\\\[/tex]
where [tex]i = \sqrt{-1}[/tex]
----------------------
The notation [tex]x=\pm i\sqrt{5}[/tex] breaks up into [tex]x=i\sqrt{5} \text{ or } x=-i\sqrt{5}[/tex]. The multiplicity of these two roots is 2 as it's the exponent of the factor [tex](x^2+5)^2[/tex]. Focus on the outermost exponent.
The notation [tex]x = \pm 5[/tex] becomes [tex]x = 5 \text{ or } x = -5[/tex]. The multiplicity of these two roots is 3 since it's the outermost exponent of the factor [tex](x^2-25)^3[/tex]
And finally, the multiplicity of the root x = 8 is 4 because it is the outermost exponent of the factor [tex](x-8)^4[/tex]

A group of 5 friends move into an apartment together to save on rent. The total monthly rent of the apartment is $4750 . Since the bedrooms are different sizes, the friends decide that each person should pay a different amount instead of splitting the rent evenly.
One of the friends named Nicole notices that her monthly rent is
D dollars less than it would be if the rent was split evenly. What is Nicole's monthly rent? Write your answer as an algebraic expression.
Answer: 950 - d
Step-by-step explanation:
4750 / 5 friends = 950.
then d dollars less is 950-d

Can somebody please help me with this math question please
Answer:
Step-by-step explanation:
isosceles triangles are ones that have two equal sides and angles. this would mean that ab is equal to bc. then you substitute the values in for AB=BC, 3x-4=5x-10. you bring the variables to one side and you flip everything which is then 2x=6 and then divide by 2. this would be x=3. then you have to figure out the AB. 3(3)-4=5. then you can always check for BC, 5(3)-10=5. and they are equal! hope i helped!

Jessica is saving money to buy a phone that costs $415. She already has $85 saved. She mows lawns to make extra money. She charges $15 per lawn that she mows. Let n be the number of lawns she needs to mow to have enough money saved to buy the phone. Which could be used to find how many lawns she needs to mow?
Answer:
22 lawns
Step-by-step explanation:
Phone= $415
Saved = $85
Money needed: $415 - $85 = $330
1 law mowed = $15
# of lawns needed to be mowed: $330 ÷ $15 = 22 lawns
Ans. = 22 lawns

Move point A to different locations to change the orientation of the parallel lines. (You'll notice that the tool keeps AB and CD parallel to each other) Be sure that points A and B do not cross EF. Do the relationships among the angles that you noted in questions 2 through 4 change if you modify the set of parallel lines this way? Explain.
Answer:
S.A for Edmentum and Plato
Like and Rate
No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
How to explain the parallel linesIf we modify the set of parallel lines by moving point A to different locations while ensuring that points A and B do not cross line EF, the relationships among the angles will not change. The statements regarding pairs of alternate interior angles being congruent, pairs of alternate exterior angles being congruent, and pairs of same-side interior angles being supplementary will still hold true.
The reason for this is that the properties of alternate interior angles, alternate exterior angles, and same-side interior angles are dependent on the fact that lines AB and CD are parallel. As long as AB and CD remain parallel, regardless of the position of point A, these angle relationships will remain consistent.
