Step-by-step explanation:

associative property

Step-by-step explanation:

2x/3 - x/3 = x/3

they both have the same denominators (number at the bottom of the fraction) so all you have to do it subtract the numerators (top of the fraction) together. 2x-x =x, that's why it's x on the numerator for the answer

hope this helps

Answer: Average of other 4 numbers =5

Step-by-step explanation:

Sum of n numbers = Average of n numbers x n

Given: Average of 6 numbers =4

so sum of 6 numbers  = 6x 4 = 24

Average of 2 numbers = 2

Sum of 2 numbers = 2 x 2 =4

Sum of rest of 4 numbers = sum of 6 numbers  - Sum of 2 numbers

= 24-4

=20

Average of 4 numbers = [tex]\dfrac{20}{4}[/tex]

i.e. Average of 4 numbers =5

Answer:

1320 cubic feet

Step-by-step explanation:

Given

[tex]Length = 24ft[/tex]

[tex]Width = 15ft[/tex]

[tex]Height = \frac{11}{3}ft[/tex] --- of water

Required

Determine the volume of the water?

Volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 24 * 15* 11/3[/tex]

[tex]Volume = 1320[/tex]

Hence, the volume of the water is 1320 cubic feet

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Step-by-step explanation:

The property justifies Francesca's first step is subtracting 2.

Here,

Original Equation is,

- 2x + 2 = -4

First step is,

-2x = -6

What is the equation?

An equation is made up of expressions that equal each other.

Now,

Original Equation is,

- 2x + 2 = -4

For find the first step;

-2x + 2 -2 = 4 - 2

-2x = -6

Hence, The property justifies Francesca's first step is subtracting 2.

Answer:

1). Option (A)

2). Option (D)

Step-by-step explanation:

1). We will use two properties of the rhombus,

   - Diagonals of a rhombus are perpendicular and bisect each other.

   - Diagonals of a rhombus bisect the opposite angles.

From the figure attached,

    m∠DBC = 49° [Given]

    m∠DBA = 49° [m∠DBC = m∠DBA]

    In ΔAOB,

    m∠AOB + m∠OBA + m∠BAO = 180° [Triangle sum theorem]

    90°+ 49° + m∠BAO = 180°

    m∠BAO = 41°

    Since, m∠DAB = 2(m∠BAO)

                              = 2(41°)

                              = 82°

Option (A) will be the answer.

2). From the figure attached,

    m∠JKF = (3y + 6)°

    m∠KFG = (7y - 14)°

    Since, m∠JKF ≅ m∠KFG

    (3y + 6) = (7y - 14)

    7y - 3y = 6 + 14

    4y = 20 ⇒ y = 5

    Option (D) will be the answer.

Answer:

1) 23a + 18

2) 23a - 6

3) 23a - 18

4) -16

5) 7a - 6

Step-by-step explanation:

Use the distributive property (if it is subtraction remember to distribute the negative sign as well)

1) 3(5a + 2) + 4(2a + 3) = (15a + 6) + (8a + 12) = 23a + 18

2) 3(5a + 2) + 4(2a - 3) = (15a + 6) + (8a - 12) = 23a - 6

3) 3(5a - 2) + 4(2a - 3) = (15a - 6) + (8a - 12) = 23a - 18

4) 3(5a - 2) - 5(3a - 2) = (15a - 6) - (15a +10) = 15a - 6 - 15a - 10 = -16

5) 3(5a + 2) - 4(2a + 3) = (15a + 6) - (8a + 12) = 15a + 6 - 8a - 12 = 7a - 6

In short, Your Answer would be Option 1.AC < AB & 2.AC > BC

Step-by-step explanation:

Here, we know largest side is always opposite to the largest angle.

As largest angle is C with 90 degree, it's opposite side which is AB must be longest here!! & AC would be second largest & BC would be smallest

The statement about the triangle is given as AB > AC > BC

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, scalene, equilateral and right angled triangle.

The size of a triangle side is proportional to the angle opposite to the side.

m∠A = 30, m∠B= 60° and m∠C = 90. Hence: AB is the greatest followed by AC and then BC

AB > AC > BC

The statement about the triangle is given as AB > AC > BC
