Step-by-step explanation:

Supplementary means the angles add up to 180°.

Add the given angles and set equal to 180°

To solve, combine like terms, add 10, divide by two to get x all by itself.

Replace x with 95 to find the measures of Angles A, C, D.

Use the supplementary definition a second time to find the measure of Angle B.

Answer:

(69/40 , 7/11)

Step-by-step explanation:

multiply the bottom equation by 2

-4x + 8y = 12

4x+3y=-5

cancel out both 4x

8y+3y=11y

12+ -5 = 7

11y=7

divide both sides by 11

y=7/11

substitute that in for y

4x + 3(7/11) = -5

4x + 21/11 = -5

4x = -69/10

x= 69/40

Answer:

5mn(2m + 6n + 1)

Step-by-step explanation:

Look at the coefficients (the numbers): 10, 30, 5

The greatest common factor of 10, 30, and 5 is 5.

Now look at the variable parts of the three terms.

Start with the variable m.

There is m², m, and m.

The GCF of m², m, and m is m.

Now look at the variable n.

There is n, n², n.

The GCF on n, n², and n is n.

The GCF for the entire polynomial is 5mn.

Now we factor out 5mn from all terms.

To factor out 5mn, you divide each term by the GCF, 5mn.

10m²n + 30mn² + 5mn = 5mn(2m + 6n + 1)

A perfect square is an expression that factors into two other expressions that are identical.  The equation that represents this model is (2x)²=4x².

A perfect square is an expression that factors into two other expressions that are identical. A monomial is a single phrase made up of a product of constants, variables, and their positive integer powers. As a result, a perfect square monomial is a monomial that factors into two monomials that are identical.

As given to us that the first row consists of tile 2x², and the second row also consists of tile 2x². Thus, the expression can be written as,

[tex]2x^2+2x^2\\\\=(2x)^2=4x^2[/tex]

Answer:

x = {-3, -2.5}

Step-by-step explanation:

Simplifying

3 + x = 0

Solving

3 + x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + x = 0 + -3

x = 0 + -3

Combine like terms: 0 + -3 = -3

x = -3

Simplifying

x = -3

Simplifying

5 + 2x = 0

Solving

5 + 2x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-5' to each side of the equation.

5 + -5 + 2x = 0 + -5

Combine like terms: 5 + -5 = 0

0 + 2x = 0 + -5

2x = 0 + -5

Combine like terms: 0 + -5 = -5

2x = -5

Divide each side by '2'.

x = -2.5

Simplifying

x = -2.5

Step-by-step explanation:

You can write an equation for this problem and solve it.

Answer:

girls = 61

boys = 73

Step-by-step explanation:

Let x = number of girls

Let y = number of boys

Given the difference between the number of the girls and the number of the boys in the outdoors club is 12:

⇒ y - x = 12

Given there are 4 times the number of the girls decreased by 25 equals 3 times the number of the boys:

⇒ 4x - 25 = 3y

Rearrange x - y = 12 to make y the subject:

⇒ y = 12 + x

Substitute x = 12 + y into 4x - 25 = 3y and solve for y:

⇒ 4x- 25 = 3(12 + x)

⇒ 4x- 25 = 36 + 3x

⇒ x = 61

Now we have found the value of x, substitute this into y = 12 + x and solve for y:

⇒ y = 12 + 61

⇒ y = 73

Step-by-step explanation:

X = 3

-14x=-42

-3/5 + x=12/5

X-5=-2

X/4=6/8

X= -3

-6+x=-9

Answer:

8) width = 30 cm

   length = 60 cm

9) first side = 60 m

   second side = 180 m

   third side = 240 m

Step-by-step explanation:

Question 8

Let W = width

Given:

⇒ Length = 3W - 30

Given:

Perimeter of a rectangle = 2W + 2L

(where W is the width and L is the length)

Substituting equation for length into the equation for the perimeter and solving for W:

   Perimeter = 2W + 2L

⇒ 180 = 2W + 2(3W - 30)

⇒ 180 = 2W + 6W - 60

⇒ 240 = 8W

⇒ W = 30 cm

Substitute found value of W into the equation for length and solve for length:

⇒ Length = 3(30) - 30

⇒ Length = 90 - 30

⇒ Length = 60 cm

Question 9

Given:

Let x = first side

⇒ second side = 3x

⇒ third side = 3x + 60

Given:

   Perimeter = sum of length of all sides

⇒ 480 = x + 3x + 3x + 60

⇒ 420 = 7x

⇒ x = 60

Therefore,

first side = 60 m

second side = 3 × 60 = 180 m

third side = 3(60) + 60 = 240 m

width be x

length=3x-30

Now

#2

sides be x,3x,3x+60

Now

Hence

The demonstration of the equation is an illustration of probability

The complete demonstration of the equation is:

3/52 = 3/13 * 13/52

In a standard deck, we have the following parameters:

Event A = Face card = 12

Event B =  Spade =13

Number of cards = 52

So, the probability that a card is a spade and a face card is:

P(A and B) = P(A) * P(B)

This gives

P(A and B) = 12/52 * 13/52

Simplify

P(A and B) = 3/13 * 13/52

Further simplify

P(A and B) = 3/1 * 1/52

Multiply

P(A and B) = 3/52

So, the complete demonstration of the equation is:

3/52 = 3/13 * 13/52

So x+4 divides [tex]2x^{3} +2x^{2} -19x+20[/tex]

If we factor out a two, we can use the quadratic formula.

2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i) or (3-i)/2 .

Antonio’s total lifetime cost will be $11680.99 after calculating all loans

Given that

Loan Amount ($)

5,894$

5,258$

Interest Rate (%)

6.9%

7.5%

Now for the loan amount 5,894$ at 6.9% interest, the amount will be

[tex]A=P(1+\dfrac{r}{h} )^{n\times t}[/tex]

[tex]A=5894(1+\dfrac{0.069}{12} )^{12\times 10}[/tex]

[tex]A=5894\times(1.00575)x^{120} =11727.76[/tex]

Now for the loan amount 5.258$ at 7.5% interest, the amount will be

[tex]A=5258(1+\dfrac{0.075}{12} )^{12\times 10}[/tex]

[tex]A=5258\times2.1120=111105.23[/tex]

So the total lifetime cost will be

[tex]=11727.76-5894+111105.23-5258=11680.99[/tex]
