Answer:

   [[. . 3 6 .][1 3 4 9 .][9 2 . 7 1][. 1 2 8 3][. 4 9 . . ]]

Step-by-step explanation:

It is helpful to remember that the first four digits {1, 2, 3, 4} total 10, and the last four digits {6, 7, 8, 9} total 30. It is also worthwhile to note that the smallest sum of two digits is 3 = 1+2, and the largest sum of 2 digits is 17 = 8+9. Some sums can only be made one way: 4 = 1+3, 16 = 7+9.

Here, we will refer to rows 1-5 from the top down, and columns 1-5 from the left to right.

__

Based on the above, column 5 can only be made one way: 1+3. Column 4 can only be made one way: 9+8+7+6. Then the choices for row 3B will be 1+7 or 5+3. We know it can't be 5+3 because 5 is not part of column 4. This makes our first fill-in (row, column) be (3,4)=7, (3,5)=1, (4,5)=3.

The sum of the remaining cells in row 4 must be 14-3 = 11, and cell (4,4) must be 6, 8, or 9. It cannot be 9, because that would require the remaining two cells to have a sum of 2, which they cannot. So, cell (4,4) is 6 or 8.

Cell (1,4) cannot be 9, either, because we cannot use 0 in cell (1,3). Then the only place for 9 in column 4 is in cell (2,4)=9.

With cell (1,4) being restricted to 6 or 8 (the two remaining numbers in column 4, cell (1,3) must be 3 or 1, and cell (2,3) must be 4 or 6. It cannot be 6 because that would require a sum of 2 in the first two cells of row 2, so (2,3)=4, (1,3)=3, and (1,4)=6. This makes (4,4)=8 and the remaining two cells of row 4 must be 1 and 2. 1 cannot go in (4,3), so we must have (4,3)=2 and (5,3)=9, (5,2)=4, (4,2)=1. That leaves 2 and 3 for rows 2 and 3 of column 2. The first two cells of row 2 must total 4, so must be 1 and 3. Cell (2,2) cannot be 1, so must be 3, leaving (2,1)=1, (3,1)=9, (3,2)=2 and that completes it.

The fill-ins are ...

  [1 3 4 9 .]

  [9 2 . 7 1]

  [. 1 2 8 3]

  [. 4 9 . . ]

Answer:

13,236 minor earthquakes occurred

Step-by-step explanation:

[tex]\frac{Part}{Total}[/tex]

"x" part amount of earthquakes

14,905 total amount of earthquakes

88.8 % part percentage of earthquakes

100% total percentage of earthquakes

[tex]\frac{x}{14905}[/tex] = [tex]\frac{88.8}{100}[/tex]

x = 14,905 × [tex]\frac{88.8}{100}[/tex]

x = 14,905 × 0.888 = 13,235.64 ≈ 13,236 minor earthquakes occurred

Answer:

6/16 is equivalent to 3/8 because after dividing the numerator (6) and denominator (16) we get 3/8.

Answer =1267.2

Step-by-step explanation:

6(3+5)26.4

6×8×26.4

48×26.4

1267.2 is the answer

[tex] - 2b - ( - 7) = 11 \\ \\ - 2b + 7 = 11 \\ \\ - 2b = 11 - 7 \\ \\ - 2b = 4 \\ \\ b = \frac{4}{ 2} \\ \\ b = 2[/tex]

Answer:

b = -2

Step-by-step explanation:

[tex] - 2b - ( - 7) = 11[/tex]

[tex] - 2b + 7 = 11[/tex]

[tex] - 2b + 7 - 7 = 11 - 7[/tex]

[tex] - 2b = 11 - 7[/tex]

[tex] - 2b = 4[/tex]

[tex]b = 4 \div( - 2) = - 4 \div 2 [/tex]

[tex]\boxed{\green{b = - 2}}[/tex]

Answer:

  264x³-66x

Step-by-step explanation:

The order of operations requires this be evaluated as ...

  11x(96x÷4x -6) . . . . given

  11x(24x·x -6) . . . . . . division inside parentheses

  11x(24x² -6) . . . . . . multiplication inside parentheses

  264x³ -66x . . . . . multiply by outside factor (use the distributive property)

_____

Additional comment

The appearance of the expression in parentheses may induce you to evaluate it as (96x)÷(4x) = 24. The order of operations requires that you do the division before the multiplication, left to right, so this must be evaluated as ...

  ((96x)÷4)x = 24x²

You need to be very careful with division and with exponents to make sure to follow the Order of Operations exactly. If you have an appropriate calculator, it will do that automatically. For example, if you tell your calculator ...

  (for x=2) 11×2×(96×2÷4×2-6)

it should give you the result 1980, not 396.

Answer:

= 198x

Step-by-step explanation:

11x × { 96x ÷ 4x -6}

11x × { 24x -6}

264x - 66x

= 198x

You got the correct answer

Answer:

example 1 is correct

a^2 - b^2 factors as (a+b)(a-b)

that is a form that math teachers want you to memorize

it is called the "difference of squares" factoring

Answer:

40

Step-by-step explanation:

Divide 30 by 3 to find 1/4. You get 10.

Multiply 10 by 4 to find 4/4. You get 40.

Answer:

The square has the greatest area.

Step-by-step explanation:

Reason:

Rectangle: The area is 5.25 in2

3/4= 0.75

7 in x 0.75 in= 5.25 in2

Square: The area is 6.25 in2

2 1/2= 2.5

2.5 in x 2.5 in= 6.25 in2

Answer:

The answer is B. 20 - 17 = 3

Step-by-step explanation:

( 3x + 5) - (2x + 7)...... x = 5

( 3(5) + 5) - ( 2(5) + 7)

( 15 + 5) - (10 + 17)

20 - 17 = 3

Thank you :)

Answer:

The answer is  20 - 17 = 3 [Choice B.]

Step-by-step explanation:

Put x = 5 into the formula (3x + 5) - (2x + 7)

[3(5)+5] - [2(5)+7]

= [15 + 5] - [10 + 7]

=20 - 17

= 3

-2a + 6b

= -2(6) + 6(-3)

= -12 + (-18)

= -30

[tex]\huge\textsf{Hey there!}[/tex]

[tex]\huge\textsf{-2a + 6b}[/tex]

[tex]\huge\textsf{= -2(6) + 6(-3)}[/tex]

[tex]\huge\textsf{= -12 + (-18)}[/tex]

[tex]\huge\textsf{= -12 - 18}[/tex]

[tex]\huge\textsf{= -30}[/tex]

[tex]\huge\textsf{Therefore, your answer is: -30}[/tex]

Answer:

[tex]\huge\boxed{-2}[/tex]

Step-by-step explanation:

Use any two points from the line.

Let them be:

(x1,y1) = (0,-2)

(x2,y2) = (-1,0)

Now,

[tex]\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-(-2)}{-1-0} \\\\Slope = \frac{2}{-1} \\\\Slope = -2\\\\\rule[225]{225}{2}[/tex]

Hope this helped!

Answer: C. -1 2/5

Step-by-step explanation:

Given expression

(-3.5) (2/5)

Convert decimal into fraction

=(-35/10) (2/5)

=[(-35 ÷ 5) / (10 ÷ 5)] (2/5)

=(-7/2) (2/5)

Simplify by multiplication

=(-7 × 2) / (2 × 5)

Cancel out 2 on both numerator and denominator

=-7/5

Convert improper fraction to mixed fraction

=[tex]\boxed{-1\frac{2}{5} }[/tex]

Hope this helps!! :)

Answer:

x = 5.5 inches.

Step-by-step explanation:

The perimeter is the sum of the 3 sides, so:-

x + x + 3 + 2x + 5 = 30

4x + 8 = 30

4x = 22

x = 5.5.
