When solving 4x – 3 = 5, the property used in the first step is the ________ property of equality. Question 13 options: A) transitive B) division C) substitution D) addition

Answer:

Triangle on the left or the first one

Step-by-step explanation:

For triangle T there is another angle which is 180-110-40= 30 degrees. Then triangle on the furtherest left is the exact same

Answer:

A circle with radius of 5 feet would have a circumference of

(2*5*PI) = 31.4159265359  

This would mean the 7 foot arc would be (7 / 31.4159265359 ) or 0.2228169203  of the circle.

0.2228169203  * 360 = 80.2140913183  degrees

80.2140913183  degrees = 1.4 radians

and 7/5 = 1.4

Therefore the answer is the second one 7 / 5

Answer:

SA=744 [tex]cm^{2}[/tex]

Step-by-step explanation:

Surface area mean the sum off every single area of the shape

so we have here two rectangle area= 14*13*2=364

and one  rectangle are in the bottom= 14*10=140 cm

and two triangle are= 10*12*2=240 cm

so the some of them is SA=364+140+240=744[tex]cm^{2}[/tex]

Answer:

(-1,0)

Step-by-step explanation:

the vertex is the highest or lowest point of a function where both lines meet and since (-1,0) is the lowest point and the next 2 are above it, so that makes (-1,0) the vertex.

Hope it helps the explanation is a little poor but I tried my hardest.

Answer:

1329.8 cm³

Step-by-step explanation:

Volume of a Cylinder is: [tex]V=\pi r^2h[/tex]

We are given the height of 14 cm, and the diameter of 11 cm.

The radius is half the diameter.

[tex]11/2=5.5[/tex]

The radius is 5.5.

I use 3.14 for pi:

[tex]V=3.14*5.5^2*14\\\rightarrow 5.5^2=30.25\\V=3.14*30.25*14\\\boxed{V=1329.79}[/tex]

1329.79 ≈ 1329.8

The volume of the cylinder should be 1329.8 cm³.

the answer is 100 because 6*21 is 126 and 126 is close to 100.

Answer:

A

Step-by-step explanation:

5x 20 = 100 so 6 would't be too far away

Answer:

The answer is option 1.

Step-by-step explanation:

Firstly, you have to elaborate the expression :

[tex] {x}^{2} + 10x + 21[/tex]

[tex] = {x}^{2} + 3x + 7x + 21[/tex]

Next you have to take out the common factors and factorize it :

[tex] {x}^{2} + 3x + 7x + 21[/tex]

[tex] = x(x + 3) + 7(x + 3)[/tex]

[tex] = (x + 7)(x + 3)[/tex]

The right answer is (X+3)(X+7)

Answer:

4x^2 -12x +9   ft^2

Step-by-step explanation:

The area of a square is

A = s^2 where s is the side length

A = (2x-3) ^2

A = (2x-3) (2x-3)

FOIL

first 2x*2x =4x^2

outer 2x (-3) = -6x

inner -3*2x = -6x

last -3*-3 = 9

Add them together

4x^2 -6x-6x +9

Combine like terms

4x^2 -12x +9

The area is 4x^2 -12x +9 ft^2

Answer:

[tex]= 4 {x}^{2} - 12x + 9 {ft}^{2} \\ [/tex]

Step-by-step explanation:

[tex]area = {x}^{2} \\ = (2x - 3)^{2} \\ = (2x - 3)(2x - 3) \\ = 2x(2x - 3) - 3(2x - 3) \\ = 4 {x}^{2} - 6x - 6x + 9 \\ = 4 {x}^{2} - 12x + 9 {ft}^{2} [/tex]

Answer:

[tex] \boxed{x \degree = 68 \degree} [/tex]

Given:

Measure of three interior angles of a quadrilateral is 55° , 117° and 120°

Step-by-step explanation:

Let the fourth interior angle be 'x'

The Interior Angles of a Quadrilateral add up to 360°

[tex] = > x \degree + 55 \degree + 117 \degree + 120 \degree = 360 \degree \\ \\ = > x \degree + 172 \degree + 120 \degree = 360 \degree \\ \\ = > x \degree + 292 \degree = 360 \degree \\ \\ = > x \degree = 360 \degree - 292 \degree \\ \\ = > x \degree = 68 \degree[/tex]

Answer:

(x - 9)² + (y - 7)² = 262

Step-by-step explanation:

x² + y² - 18x - 14y - 132 = 0

Rearranging the equation:

y² - 14y + x² - 18x - 132 = 0

add 132 to both sides:

y² -14y + x² - 18x - 132 + 132 = 0 + 132

y² -14y + x² - 18x = 132

add to both sides the square of half of the coefficient of y (i.e (14/2)² = 49)

y² -14y + 49 + x² - 18x = 132 + 49

add to both sides the square of half of the coefficient of x (i.e (18/2)² = 81)

y² -14y + 49 + x² - 18x + 81 = 132 + 49 + 81

y² -14y + 49 - x² - 18x - 81 = 262

y² - 7y - 7y + 49 + x² - 9x - 9x - 81 = 262

y(y - 7) - 7(y - 7) + x (x - 9) -9(x - 9) = 262

(y - 7)(y - 7) + (x - 9)(x - 9) = 262

(y - 7)²+ (x - 9)² = 262

(x - 9)² + (y - 7)² = 262

The coefficient of 7c + 8 is the coefficient of the term with the variable c, which is 7.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Unknown variables, numbers, and arithmetic operators make up an algebraic expression. It contains no equality or inequality symbols.

The given expression is 7c + 8.

A coefficient is a numerical factor that appears before a variable in a term. In this expression, 7c is a term, where 7 is the coefficient of c. Similarly, 8 is also a term, where the coefficient is 8.

Since integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer.

Therefore, the coefficient of 7c + 8 is the coefficient of the term with the variable c, which is 7.

So, the answer is option 3, which is 7.

Answer:

Inscribed angle theorem

Step-by-step explanation:

This theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

In this case, the angle is ∠LMN and the arc is arc LN. Arc LN measures 180°,  because segment LN is the diameter of the circle. Then, by the theorem:

∠LMN = (1/2)*arc LN = (1/2)*180° = 90°

Answer:

B. Inscribed Angle theorem

Answer:

x = 20

Step-by-step explanation:

x in (-oo:+oo)

(1/2)*x+6 = 16 // - 16

(1/2)*x-16+6 = 0

1/2*x-10 = 0 // + 10

1/2*x = 10 // : 1/2

x = 10/1/2

Isha Pathak

Answer:

It is D.

Step-by-step explanation:

Answer:

A =315 cm^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2) *h

where b1 and b2 are the lengths of the bases and h is the height

A = 1/2 ( 13+29) *15

A  = 1/2 (42)* 15

A =315 cm^2

Answer:

[tex]315 {cm}^{2} [/tex]

Step-by-step explanation:

[tex]area \\ = \frac{1}{2} \times (a + b) \times h \\ = \frac{1}{2} \times (13 + 29) \times 15 \\ = \frac{1}{2} \times 42 \times 15 \\ = \frac{630}{2} \\ = 315 {cm}^{2} [/tex]

Answer:

5 hours because 50 multiply by 5 is 250 and more 75 for radiator

Answer:

Step-by-step explanation:

a₁₅ = 33.5  

S₁₅ = 240

So, there are 15 terms in this arithmetic progression. So, l = a₁₅ = 33.5

Sn = (n/2)(a+l)

[tex]S_{15}=\frac{15}{2}(a_{1}+l)\\\\240=\frac{15}{2}(a_{1}+33.5)\\\\240*2=15*(a_{1}+33.5)\\\\480=15*(a_{1}+33.5)\\\\\frac{480}{15}=a_{1}+33.5\\\\32=a_{1}+33.5\\\\32-33.5=a_{1}\\-1.5=a_{1}[/tex]
