Which algebraic expression represents the total amount that Kelly and Dante have?
A: d-25
B:25d
C:25-d
D:25+d
Answer:
Option D: 25 + d
Step-by-step explanation:
Kelly is having money in her purse = $25
Dante has in his wallet = $d
By adding both value we can get the total amount that Kelly and Dante have.
Therefore, 25 + d is the expression that represents the total amount that Kelly and Dante have.
Option D: 25 + d is the answer.

Part1: Use the distributive property to remove the parentheses.
Part2: Collect any like terms on both sides of the equation.
Part3: Bring all variable terms to one side of the equation. (Hint: Add x to both sides)

What's 17= z- (-9) days
The calculated value of z in the equation 17 = z - (-9) is 8
How to determine the value of z in the equation
From the question, we have the following parameters that can be used in our computation:
17 = z - (-9)
When the bracket is evaluated, we have
17 = z + 9
So, we have
z = 17 - 9
Evaluate
z = 8
Hence, the value of z in the equation is 8

Which property is NOT used when solving 15=2x-1
The associative property is not used when solving the given equation.
Explanation:The property that is NOT used when solving the equation 15=2x-1 is the associative property.
The associative property states that the grouping of numbers does not affect the result of addition or multiplication. However, in this equation, there is no need to group the numbers in a different way.
Thus, the answer to the equation is:
15 = 2x - 1
Solving for x:
15 + 1 = 2x
16 = 2x
Divide both sides by 2:
16/2 = x
8 = x

The requried transformation of g(x) is 4 units right and 2 units up on the coordinate plane.
What are functions?Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The transformation from g(x) = x² - 2 to g(x) = (x + 4)² involves a horizontal translation of 4 units to the left. This means that the vertex of the parabola has shifted 4 units to the left from its original position. Additionally, there is no vertical translation (i.e., the value of "a" remains the same), and the shape of the parabola remains the same. Therefore, the transformation is a horizontal translation.
Thus, the requried transformation of g(x) is 4 units right and 2 units up on the coordinate plane.

За 7 кг груш заплатили 525 руб. Сколько рублей следует заплатить за 4,6 кг груш?
Answer: 345 руб.
Step-by-step explanation:
525 : 7 = 75 (руб.) - стоимость 1 кг груш.
4,6 * 75 = 345 (руб.) - следует заплатить за 4,6 кг груш.
To find out how much to pay for 4.6 kg of pears, calculate the price per kilogram from the given 7 kg cost (525 rubles) and multiply by 4.6 kg, resulting in a price of 345 rubles for 4.6 kg.
Explanation:The cost for 7 kg of pears is 525 rubles. To determine how much one should pay for 4.6 kg of pears, we use a simple proportion based on the principle that the price per kilogram remains constant.
First, we find the price per kilogram by dividing the total cost by the weight:
Price per kilogram = Total cost / Total weight in kgPrice per kilogram = 525 rubles / 7 kg = 75 rubles/kgNow, we multiply the price per kilogram by the desired weight to get the total cost for 4.6 kg:
Total cost for 4.6 kg = Price per kilogram * Weight of the pearsTotal cost for 4.6 kg = 75 rubles/kg * 4.6 kg = 345 rublesTherefore, one would need to pay 345 rubles for 4.6 kg of pears.

Find the missing measure for a right circular cone given the following information. Find r if T.A. = 12pi and L.A. = 8pi
Answer:
r = 2 units
Step-by-step explanation:
Total area(T.A) of the circular cone is given by:
[tex]\text{T.A} =\pi r^2+ \pi r\sqrt{r^2+h^2}[/tex]
Lateral surface area(L.A) of the circular cone:
[tex]\text{L.A} = \pi r\sqrt{r^2+h^2}[/tex]
where
r is the radius and h is the height of the circular cone.
As per the statement:
[tex]T.A = 12 \pi[/tex] and [tex]L.A = 8 \pi[/tex]
then;
[tex]T.A -L.A = \pi r^2+ \pi r\sqrt{r^2+h^2}-\pi r\sqrt{r^2+h^2}[/tex]
⇒[tex]12 \pi -8 \pi = \pi r^2[/tex]
⇒[tex]4 \pi =\pi r^2[/tex]
Divide both sides by [tex]\pi[/tex] we have;
[tex]4 =r^2[/tex]
or
[tex]r^2 = 4[/tex]
⇒[tex]r= \pm\sqrt{4} =\pm 2[/tex]
r cannot be in negative
⇒[tex]r = 2[/tex] units
Therefore, radius of the circular cone is, r = 2 units
Which statement is true about this argument?
Premises: If two angles form a linear pair, then they are supplementary.
If two angles are supplementary, then the sum of their measures is 180°.
Conclusion: If two angles form a linear pair, then the sum of their measures is 180°.
The argument 'If two angles form a linear pair, then the sum of their measures is 180°' is valid. This conclusion is logically drawn from the premises stating that a linear pair of angles are supplementary, and that supplementary angles have a sum of 180°.
Explanation:The statement 'If two angles form a linear pair, then the sum of their measures is 180°' is indeed true based on the provided premises. Here's why:
If two angles form a linear pair, according to the first premise, they are supplementary.Supplementary angles are those where the sum of their measures is 180°, as stated in the second premise.Therefore, if two angles form a linear pair (making them supplementary), then the sum of their measures is indeed 180°, which is the conclusion given.So, the argument is valid and the conclusion is correctly drawn from the premises.

A computer cost 1389.93 including tax if the tax rate is 7% find the price of the computer before taxes
Answer:
Cost of the computer before taxes is $1299.
Step-by-step explanation:
Let the price of the computer before taxes is = $x
Tax rate on this computer = 7%
Therefore, computer cost including tax = (x + 7% of x)
= [tex]x+\frac{7x}{100}[/tex]
= x + 0.07x
= $(1.07x)
Cost of the computer including tax is given as $1389.93.
Therefore, 1389.93 = 1.07x
x = [tex]\frac{1389.93}{1.07}[/tex]
= $1299
Cost of the computer before taxes is $1299.
