Answer:

the cost of one sweater is $40

Step-by-step explanation:

The computation of the cost of the one sweater is shown below;

Let us assume the sweater be x

And, the pant be y

Now the equations are

2x + y = $120 ..............(1)

x + 2y = $120................(2)

Now multiply by 2 in equation 1

4x + 2y = $240

x + 2y = $120

3x = $120

x = $40

Hence, the cost of one sweater is $40

The constant of Proportionality of wins to loses is 12.

Given, The total no. of games won by team is 84 and the team loses 6 games in the season.

When two or more parameters are directly or indirectly proportional to one another, their relationship is expressed as a = kb or a = k/b, where k indicates how the two variables are related. This k is known as the proportionality constant.

So, let a = Total no. of games won by team

and b = no. of games lost by team

So, proportionality constant (k) = Total no. of games won by team(a)  / no. of games lost by team(b)

k = 84/6

k = 12.

Hence, the proportionality constant is 12.

Answer:

  8m³ -4m² +3m

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of its three sides. Here, you're given the perimeter and two of the sides. The third side will be the length that makes up the difference.

  P = side 1 + side 2 + side 3

  18m³ +2m² -m = (5m³ +3m² -2m) +(5m³ +3m² -2m) + side 3

  18m³ +2m² -m = (10m³ +6m² -4m) + side 3 . . . . . collect terms

  18m³ +2m² -m - (10m³ +6m² -4m) = side 3 . . . . . subtract (10m³ +6m² -4m)

  m³(18 -10) +m²(2 -6) +m(-1 +4) = side 3 . . . . . . . . . group like terms

  8m³ -4m² +3m = side 3

Given:

[tex]\dfrac{5}{6+2i}[/tex]

To find:

The  quotient in the form a + bi.

Solution:

We have,

[tex]\dfrac{5}{6+2i}[/tex]

Multiply numerator and denominator by 6-2i.

[tex]=\dfrac{5\times (6-2i)}{(6+2i)\times (6-2i)}[/tex]

[tex]=\dfrac{5(6)+5(-2i)}{6^2+(2i)^2}[/tex]

[tex]=\dfrac{30-10i}{36+4i^2}[/tex]

[tex]=\dfrac{30-10i}{36+4(-1)}[/tex]    [tex][\because i^2=-1][/tex]

On further simplification, we get

[tex]=\dfrac{30-10i}{36-4}[/tex]

[tex]=\dfrac{30-10i}{32}[/tex]

[tex]=\dfrac{30}{32}-\dfrac{10i}{32}[/tex]

[tex]=\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex]

Therefore, the form a+bi is [tex]\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex], where, [tex]a=\dfrac{15}{16}[/tex] and [tex]b=(-\dfrac{5}{16})[/tex].

Answer:  second and fourth choices have infinitely many solutions

Step-by-step explanation:

When you combine the like terms in those two equations you end up with an "identity." Both sides of the equation are the same.

x - 1/3(3x) = 0 . 1/3 of 3x is 1x

x - x = 0  any number minus itself is 0

or add x to both sides  x-x+x = 0 + x  

x = x is an identity. An identity has infinite solutions.

3x + 2 - 1/3(3x) = 2 + 2x

3x + 2 -x = 2 + 2x

2x +2 = 2 + 2x . same thing! Infinite solutions.

The measure of angle x is 140°

For given question,

We are given that a pair of parallel lines is cut by a transversal line .

Let a pair of parallel lines are PQ and RS and the transversal line AB cut the parallel lines PQ and RS.

We are given that an exterior angle on the left side of the transversal line is 40 degrees.

The interior angle on the right side of transversal line is x which is not vertical opposite to exterior angle = 40 degrees

We know that when two lines are parallel and cut by a transversal line then corresponding angles are congruent.

So, angle MNR = 40°

Also, ∠MNR + ∠MNS = 180°           ...............(linear pair of angles)

⇒ 40° + x = 180°

⇒ x = 140°

Therefore, the measure of angle x is 140°

The given statement is false because the total number of toes and fingers are 30 and not 35.

We are told that If a thumb is a finger, then three gloves and three shoes normally hold thirty-five fingers and toes.

Now, we know that a glove has space for 5 fingers. This means that three gloves would have a total of; 5 * 3 = 15 fingers

Now, a shoe has space for 5 toes. Thus;

Three shoes would have a total of; 5 * 3 = 15 toes

Thus;

Total fingers and toes = 15 + 15 = 30

Thus, we conclude that the given statement is false because the total number of toes and fingers are 30 and not 35.

Answer:

The linear function is;

Tn-1 = Tn + 3

What this mean is that to get the term before the present term, we add 3 to the present term

Step-by-step explanation:

Here, we want to write a liner function to describe the function

As we can see from the numbers listed,

the next term is simply obtained by deducting 3 from the previous term

We can write this as:

Tn-1 = Tn + 3

Where Tn is the next term and Tn-1 is the previous term

What the function is saying is that to get the term before the present term, we add 3 to the present term

[tex]x=1,\:y=-3[/tex]

As the system of equations has only one solution, thus the solution consistent.

Step-by-step explanation:

Given the system of equations

4x - 5y = 19

y = x - 4

Solving the system of equations by using the substitution method.

[tex]\begin{bmatrix}4x-5y=19\\ y=x-4\end{bmatrix}[/tex]

[tex]\mathrm{Subsititute\:}y=x-4[/tex]

[tex]\begin{bmatrix}4x-5\left(x-4\right)=19\end{bmatrix}[/tex]

[tex]-x+20=19[/tex]

isolate x for [tex]-x+20=19[/tex]

[tex]-x+20=19[/tex]

[tex]-x=-1[/tex]

The solution is

Cups of sugar = 1/2 cups , Cups of flour = 1 cup

Cups of sugar = 3/4 cups , Cups of flour = 1 1/2 cups

Cups of sugar = 7/8 cups , Cups of flour = 1 3/4 cups

Cups of sugar = 1 cup , Cups of flour = 2 cups

Cups of sugar = 5/4 cups , Cups of flour = 2 1/2 cups

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of cups of sugar = S

Let the number of cups of flour = F

Now , the equation will be

1/2 cups of sugar will result in = 1 cup of flour

So , the ratio of S : F = 1 : 2

Now ,

3/4 cups of sugar will result in = 2 x 3/4 cups of flour

3/4 cups of sugar will result in = 6/4 cups of flour

3/4 cups of sugar will result in = 3/2 cups of flour

Now ,

S cups of sugar will result in = 1 3/4 cups of flour

S cups of sugar will result in = 7/4 cups of flour

S cups of sugar = ( 1/2 ) ( 7/4 ) cups

S cups of sugar = 7/8 cups

7/8 cups of sugar = 1 3/4 cups of flour

Now ,

1 cup of sugar = 2 x 1 cups of flour

1 cup of sugar will result in = 2 cups of flour

Now ,

S cups of sugar will result in = 2 1/2 cups of flour

S cups of sugar = 5/2 cups of flour

S cups of sugar = ( 1/2 ) x ( 5/2 ) cups

S cups of sugar = 5/4 cups

5/4 cups of sugar = 2 1/2 cups of flour

Hence ,

Cups of sugar = 1/2 cups , Cups of flour = 1 cup

Cups of sugar = 3/4 cups , Cups of flour = 1 1/2 cups

Cups of sugar = 7/8 cups , Cups of flour = 1 3/4 cups

Cups of sugar = 1 cup , Cups of flour = 2 cups

Cups of sugar = 5/4 cups , Cups of flour = 2 1/2 cups

Negation of square root is never considered a number while rest any number comes under the category of the Real number

The Numbers here are divided into two categories: Real and Imaginary. In addition to being divided into Rational and Irrational numbers. In the category of rational numbers, fractions and integers  fall under the category. The decimal numbers which are unconvertable to the fraction  form are known as irrational numbers. This means that here in the question √-15 = 15i(where i = √-1, the imaginary number)

Hence √-15 is not considered a number while  -1.96312... comes under the category of a Real Number.

Answer:

The growth rate is 0.6

The growth factor is 1.6

Step-by-step explanation:

Generally, the exponential equation can be written as;

y = a(1 + r)^x

Where a is the initial value of 100

r is the growth rate

So let us form equations;

160 = 100(1 + r)^1 •••••(i)

Also;

256 = 100(1 + r)^2 •••••••(ii)

Divide equation ii by i

256/160 = 1 + r

1.6 = 1 + r

r = 1.6-1
