rob has 8 dimes and 17 nickels in $1.65

There is only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All the points fall on the same line when the values that together make a linear equation true are determined and plotted on a coordinate grid.

Let n represent nickels & d dimes

given: n + d = 25 #1 (number of coins)

given: .05n + .10d = 1.65 #2 (amount in dollars)

n = 25 - d #3 (rewrite of #1)

.05(25 -d) + .10d = 1.65 (substitute #3 in #2)

1.25 - .05d + .10d = 1.65 (multiply out the left side)

.05d = .40 (collection of like terms)

d = 8 (divided both sides by.05)

n + 8 = 25 (substitute answer for d in #1)

n = 17 (subtract both sides by 8)

There are 8 dimes and 17 nickels.

Step-by-step explanation:

Answer:

x= -3

Step-by-step explanation:

[tex]2(2x + 3) = x - 3 \\ 4x + 6 = x - 3 \\ 4x = x - 3 - 6 \\ 4x - x = - 3 - 6 \\ 3x = - 9 \\ x = \frac{ - 9}{3} \\ x = - 3[/tex]

Answer:

[tex]x=-3 \textsf{ \quad or \quad} x=-\dfrac{3}{5}[/tex]

Step-by-step explanation:

Given absolute value equation:

[tex]2|2x+3|=|x-3|[/tex]

The absolute value of a number is its positive numerical value.

Therefore, the expressions inside the bars should be set to both positive and negative.  Rewrite the absolute value equation as four equations without absolute value bars and simplify:

[tex]\textsf{Positive = Positive}: \quad 2(2x+3)=x-3[/tex]

[tex]\textsf{Positive = Negative}: \quad 2(2x+3)=-(x-3)[/tex]

[tex]\begin{aligned}\textsf{Negative = Positive}: \quad -2(2x+3) &=x-3\\ \implies 2(2x+3) &=-(x-3)\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Negative = Negative}: \quad -2(2x+3) &=-(x-3)\\ \implies 2(2x+3)&=x-3\end{aligned}[/tex]

From inspection of the equations:

so there are only two unique equations to be solved.

Equation 1

[tex]\begin{aligned}2(2x+3) & =x-3\\4x+6 & = x-3\\4x+6-x&=x-3-x\\3x+6&=-3\\3x+6-6&=-3-6\\3x & =-9\\\dfrac{3x}{3} & = \dfrac{-9}{3}\\ x&=-3 \end{aligned}[/tex]

Equation 2

[tex]\begin{aligned}2(2x+3)&=-(x-3)\\4x+6&=-x+3\\4x+6+x&=-x+3+x\\5x+6&=3\\5x+6-6&=3-6\\5x &=-3\\ \dfrac{5x}{5}&=\dfrac{-3}{5}\\x &=-\dfrac{3}{5} \end{aligned}[/tex]

Therefore, the solutions are:

[tex]x=-3 \textsf{ \quad or \quad} x=-\dfrac{3}{5}[/tex]

The sum of the finite series  [tex]\sum\limits^{8}_{n=1} {(7-n)}[/tex]  is 20

Given a finite series:

[tex]\sum\limits^{8}_{n=1} {(7-n)}[/tex]

Recall the properties of summation notation:

Σₙ b. f(n) = b Σₙ f(n) where b is a constant.

Σ (a + b) = Σ a +  Σ b

[tex]\sum\limits^p_{n=1} {b} =b.p[/tex]  where b is a constant

Using the above summation properties, we can write:

[tex]\sum\limits^{8}_{n=1} {(7-n)}=\sum\limits^{8}_{n=1} {7}-\sum\limits^{8}_{n=1} {n}[/tex]

=7 . 8 - (1+2+3+ ...+8)

= 56 - 8/2 (1+8)

If 22 is the geometric mean of a number and four times the number, then the number is 11.

Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.

To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.

The formula for the geometric mean is given by:

GM = n√x1 x2 . . . xn

Let x = x1 = unknown number

y = x2 = four times the number = 4x

Using the formula in solving geometric mean, plug in the values and variables.

GM = n√x1 x2 . . . xn

22 = √xy

22 = √x(4x)

22 = √4x^2

22 = 2x

x = 11

y = 4x

y = 44

Hence, the number is 11. 22 is the geometric mean of 11 and 44.

Answer: n=-7

Step-by-step explanation:

5n - 7n = 14

(5-7)n=14

-2n=14

-2n/(-2)=14/(-2)

n=14/(-2)

n=-7

The equation is,

→ 5n - 7n = 14

Solving for the value of n,

→ 5n - 7n = 14

→ -2n = 14

→ n = -(14//2)

→ [ n = -7 ]

Thus, the value of n is -7.

The average hockey player makes per game is an amount of $34,000.00 which is the correct option would be option (A).

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

The average professional hockey player makes $2.78 million a year.

$2.78 million = $2,780,000

They play an average of 82 games.

The average hockey player makes per game = 2,780,000 / 82

Apply the division operation to get the answer.

The average hockey player makes per game = 33,902.439

The average hockey player makes per game = $33,900.00

The following volume quantities are listed below:

a) 2 pints, 1 qt

b) 12 pints, 6 qt

c) 5 pints, 2.5 c

d) 6.75 pints, 3.375 fl oz

In this question we must transform a quantity in a unit to another quantity in a unit of the same kind. For instance, if we have a quantity in a mass unit, then we only can convert it into another mass unit.

Herein we have four unit conversion cases for volumes, both pints and quarts are volume units commonly used in the United States. There are the following equivalencies:

Now we proceed to convert each quantity to pints and quarts by cross multiplication:

a) 32 fl oz × 2 pints / 32 fl oz = 2 pints, 32 fl oz × 1 qt / 32 fl oz = 1 qt

b) 24 c × 2 pints / 4 c = 12 pints, 24 c × 1 qt / 4 c = 6 qt

c) 10 c × 2 pints / 4 c = 5 pints, 10 c × 1 qt / 4 c = 2.5 c

Step-by-step explanation:

Basically the triangles are congruent. Therefore, the sides are equal to each other. Set both equations equal to each other and solve for x.

A Figure ABCD is a rhombus. The angles of A and C are equal by alterenate interior angle. The value of x in the figure ABCD rhombus is 9 degree.

We know that rhombuses are a particular type of quadrilateral in Euclidean geometry. It is a unique instance of a parallelogram in which the diagonals meet at a 90-degree angle and all sides are equal.

The Solution to an equation is finding values of the variable in the considered equation for which the equation considered evaluates to be true.

For a solution, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, thus solution to a system is the intersection of all its equation at single point

WE know that the diagonals of a rhombus bisect each other, we know that triangle DEC is a right triangle.

Since the side lengths of a rhombus are equal, so the angles of A and C are equal by alterenate interior angle.

Now, 5x-8 = 3x + 10

i.e. 5x - 3x = 10 + 8

i.e. 2x = 18

i.e. x = 9

Therefore the value of x in the figure ABCD is 9 degree.

The equation of the circle that passes through the point (-2 , 3) and has a center at the origin is x^2 + y^2 = 13.

Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-2 , 3).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(-2 - 0)^2 + (3 - 0)^2

radius= √4 + 9

radius = √13

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (0 , 0)

r = √13

(x - 0)^2 + (y - 0)^2 = (√13)^2

By calculating speed of each person we can find who is faster.

Speed can be defined as the distance covered with respect to time. It is a scalar quantity. It is calculated as follows

Speed  = Distance / Time taken

The time taken by each person is 20 seconds.

Distance covered by Jan = 50 meter

Speed of Jan = Distance / Time taken

Speed of Jan = 50 / 20

Speed of Jan = 2.5 meters per second

Distance covered by Dingh = 60 meter

Speed of Dingh = Distance / Time taken

Speed of Dingh = 60 / 20

Speed of Dingh = 3 meters per second

Since the speed of Dingh is more than Jan, we can say that Dingh is faster.

Distance = Speed × Time taken

Here, time taken = 1 second

This implies Distance Covered = Speed

Therefore, Jan covers 2.5 meters in one second while Dingh covers 3 meters in one second.
