Answer:

The expression is;

Number of books = length of box/thickness of book

= 81/2/9 = 81 books

Step-by-step explanation:

Here, we want to determine the number of books that will fit into a box given the length of the book and the box.

The expression that can be used to get the number of books will be;

Number of books = length of box/thickness of book

= 18 divided by 2/9

= 18 * 9/2 = 81 books

Answer:

18 divided by 2/9

Answer:

Step-by-step explanation:

Given that the owls heart weighs 1.072 grams

and the Whale's heart weighs 400lbs

let us convert from pounds to grams to have a uniform unit

400lbs = 181,437grams

Now when two readings or quantities are two orders apart it means that they differ by a factor of 100

let us solve for the difference between the two hearts

181,437grams- 1.072 grams= 181 435.928 grams

the difference is more than two orders, hence the statement is not correct

See Explanation

Step-by-step explanation:

1.

Given

[tex]y = 6x - 11[/tex]

[tex]-2x - 3y = -7[/tex]

Solve for x and y

In the first equation, we have: [tex]y = 6x - 11[/tex]

Substitute [tex]6x - 11[/tex] for [tex]y[/tex] in the second

[tex]-2x - 3y = -7[/tex]

[tex]-2x - 3(6x - 11) = -7[/tex]

[tex]-2x - 18x + 33 = -7[/tex]

[tex]-20x+ 33 = -7[/tex]

[tex]-20x= -7-33[/tex]

[tex]-20x= -40[/tex]

Divide through by -1

[tex]20x = 40[/tex]

[tex]x = 40/20[/tex]

[tex]x = 2[/tex]

Recall that:

[tex]y = 6x - 11[/tex]

[tex]y = 6 * 2 - 11[/tex]

[tex]y = 1[/tex]

2,

Given

[tex]-3x - 3y = 3[/tex]

[tex]y = -5x - 17[/tex]

In the second equation, we have: [tex]y = -5x - 17[/tex]

Substitute [tex]-5x - 17[/tex] for [tex]y[/tex] in the first equation

[tex]-3x - 3y = 3[/tex]

[tex]-3x - 3(-5x - 17) = 3[/tex]

[tex]-3x + 15x + 51 = 3[/tex]

[tex]12x + 51 = 3[/tex]

[tex]12x=3 - 51[/tex]

[tex]12x=-48[/tex]

[tex]x = -48/12[/tex]

[tex]x = -4[/tex]

Recall that: [tex]y = -5x - 17[/tex]

[tex]y = -5 * -4 - 17[/tex]

[tex]y = -3[/tex]

3. Given

[tex]-4x + y = 6[/tex]

[tex]-5x - y = 21[/tex]

Add both equations to eliminate y

[tex]-4x - 5x + y - y = 6 + 21[/tex]

[tex]-9x= 27[/tex]

Solve for x

[tex]x = 27/-9[/tex]

[tex]x = -3[/tex]

Substitute -3 for x in the first equation: [tex]-4x + y = 6[/tex]

[tex]-4 * -3 + y = 6[/tex]

[tex]12 + y = 6[/tex]

[tex]y = 6 - 12[/tex]

[tex]y = -6[/tex]

4. Given

[tex]-7x - 2y = -13[/tex]

[tex]x - 2y = 11[/tex]

Make x the subject in the second equation

[tex]x - 2y = 11[/tex]

[tex]x = 11 + 2y[/tex]

Substitute 11 + 2y for x in the first equation

[tex]-7x - 2y = -13[/tex]

[tex]-7 (11 + 2y) - 2y = -13[/tex]

[tex]-77 -14y - 2y = -13[/tex]

[tex]-77 -16y = -13[/tex]

[tex]-16y = -13 + 77[/tex]

[tex]-16y = 64[/tex]

[tex]y = 64/-16[/tex]

[tex]y = -4[/tex]

Substitute -4 for y in [tex]x = 11 + 2y[/tex]

[tex]x = 11 + 2 * -4[/tex]

[tex]x = 11 -8[/tex]

[tex]x = 3[/tex]

5. Given

[tex]-2x + 6y = 6[/tex]

[tex]-7x + 8y = -5[/tex]

Multiply the first equation by 7 and the second by - 2 to eliminate x

The first

[tex]7(-2x + 6y = 6)[/tex]

[tex]-14x + 42y =42[/tex]

The second

[tex]-2(-7x + 8y = -5)[/tex]

[tex]14x - 16y = 10[/tex]

Add the resulting equations

[tex]-14x + 42y =42[/tex]

[tex]14x - 16y = 10[/tex]

------------------------------

[tex]-14x + 14x + 42y - 16y = 42 + 10[/tex]

[tex]42y - 16y = 42 + 10[/tex]

[tex]26y = 52[/tex]

Solve for y

[tex]y = 52/26[/tex]

[tex]y = 2[/tex]

Substitute 2 for y in [tex]-2x + 6y = 6[/tex]

[tex]-2x + 6 * 2 = 6[/tex]

[tex]-2x + 12 = 6[/tex]

[tex]-2x = 6 -12[/tex]

[tex]-2x = -6[/tex]

Solve for x

[tex]x = -6/-2[/tex]

[tex]x = 3[/tex]

Answer:

1. Angle 1 congruent to Angle 3, Angle 2 congruent to Angle 4 ( top row last box in answer choices)

2. Reflexive Property of Congruence

3. Angle DGF congruent to Angle DEF

Step-by-step explanation:

Opposite sides of a parallelogram are parallel , so angle 1 ≅ angle 3 and angle 2 ≅ angle 4 because they are alternate interior angles . By the reflexive property of congruence DF ≅ DF . Therefore , △ DGF ≅ △ DEF by the ASA congruence postulate . That means DE ≅GF and DG ≅EF by CPCTC .

Answer:

Step 2 was the first mistake and the second option is the answer.

Step-by-step explanation:

Julia incorrectly factored the -1 from the second group of terms.

The correct option is (B)

An expression is a sentence with a minimum of two numbers or variables and at least one math operation.

Given:

2x^4 + 2x³ -x²-x

While solving the above expression in the third step

x(2x²(x+1)) - 1(x-1)

should be

x(2x²(x+1)) - 1(x + 1)

Hence, Julia incorrectly factored the -1 from the second group of terms.

Answer:

Step-by-step explanation:

-3 plus 3 equals 0 and 5 minus 7 equals -2, so (0,-2).

Answer:

A

Step-by-step explanation:

Take a look at the slope-intercept form of the equation .

[tex]y=mx+c[/tex]

Slope of 9/7 and y-intercept of 1/3 means replace m which is slope and c is the y-intercept which becomes

[tex]y=\frac{9}{7}x+\frac{1}{3}[/tex]

now we take LCM of 7 and 3 which becomes

[tex]y=\frac{27x+7}{21}[/tex]

and then,

[tex]21y=27x+7[/tex]

so A is our Answer

if arrange the equation accordingly

Answer:

A) 102

Step-by-step explanation:

Alternative Exterior Theorem: If two parallel lines are cut by a transversal, then the pairs of alternative exterior angles are congruent.

Because of this theorem, we know that <2 and <8 are congruent, so we can set these equations to be equal to each other, like so:

2x + 50 = x + 76

Then, we need to find the x value, so solve from there.

2x + 50 = x + 76

x + 50 = 76   [Subtract x from both sides of the equal sign]

x = 26   [Subtract 50 from both sides of the equal sign]

So now that we have our x value, all we have to do is plug in that value to the <2 equation.

2x + 50

2(26) + 50

52 + 50

102
