can u guys please help me!!

Answer:

True ; false ; False ; true

Step-by-step explanation:

Equation 1:

7 20 + □ = 19 20

19 / 20 - 7/20

(19 - 7) / 20

12/ 20 = 3/5

Equation 2:

□ + 3 10 = 3 15

3/5 + 3/10

(6 + 3) / 10 = 9/10

Equation 3:

1 2 + 2 3 = □

1/ 2 + 2/3

(3 + 4) / 6

7 / 6

Equation 4:

1 10 + 1 2 = □

1/10 + 1/2

(1 + 5) / 10

6 / 10 = 3/5

Step-by-step explanation:

3-2(3x+1)=19

[tex]3 - 6x - 2 = 19 \\ 1 - 6x = 19 \\ - 6x = 19 - 1 \\ - 6x = 18 \\ x = - 3[/tex]

Answer:

B.

Step-by-step explanation:

The sets {1, 2, 3}, {0}, {-4, -1, 0, 5, 10} only include integers which makes the statement true. Since they are all integers they are all subsets.

Answer {2.5, 3.5, 4.5} does not include integers so therefore it is not a subset making the statement false.

Answer:

A

Step-by-step explanation:

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just don’t want to waste my time in case you don’t want me to :)

Answer:

x ≤ - [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Given

3x + 14 ≤ 13 ( subtract 14 from both sides )

3x ≤ - 1 ( divide both sides by 3 )

x ≤ - [tex]\frac{1}{3}[/tex]

Answer:

Step-by-step explanation:

3x+14≤13

x

[tex]step - 1 \colon \: define[/tex]

[tex]3x + 14 \leqslant 13[/tex]

[tex]step - 2 \colon \: subtract[/tex]

[tex]3x + 14 - 14 \leqslant 13 - 14[/tex]

[tex]3x \leqslant - 1[/tex]

[tex]step - 3 \colon \: divide[/tex]

[tex] \frac{3}{3} x \leqslant - \frac{1}{3} [/tex]

[tex]x \leqslant - \frac{1}{ 3} [/tex]

Answer: The cost is 3.75

Step-by-step explanation: Since you wrote, 1 dozen eggs costs about 3.75, your question was, "What is the cost for 1 dozen eggs?" So the answer should be 3.75.

Answer:

Option A

Step-by-step explanation:

Answer:

1.You draw the rectangle and label on one side 20m

2.Draw a diagonal line inside the rectangle an label the line as 29m

3.Extract the the newly formed right angled triangle.

4.Find the hypotenuse (a+b=c) of the right angle which will give you the value of the unknown side.

5.Calculate the perimeter which is;

P=S+S+S+S

P= 20m+9m+20m+9m

P=29m+29m

P=58m

Hey there!

Answer:

180 people carry cell phone

Step-by-step explanation:

each number is a percentage so you can figure out all the percentages of the bottom and right

0.72 carry cell phone

180 carry cell phone

0.28 dont carry cell phone

70 people dont carry cell phone

0.58 are female

145 are female

0.42 are male

105 are male

therefore that leaves the 180 people carry cell phone

The answer is 20 Km/hr

first : you have miles . then change it into Km .

second: 45 min to sec

finally speed is the distance per unit time

Answer:

constant of variation:  k = -24

y = 12 when x = -2

Step-by-step explanation:

y varies inversely with x equation is:  y = k/x

where 'k' if the constant of variation

plug in:

4 = k/-6

cross-multiply to get value of 'k' which is -24

plug in:

y = -24/-2

y = 12

Answer:

83 3/10

Step-by-step explanation:

multiple the numbers

Answer:

Yes it is possible to have an increase of 100%.

Retail price is 83.4$

Step-by-step explanation:

250 = x + (200% of x)

250 = 300% of x

so basically 250$ = 3x

250/3 = 83.3333334

So you can round it to $83.4

Hope this helps. I'm not entirely sure this is true but I hope it is.

Answer:

true

Step-by-step explanation:

Answer: False

explanation:

Its proof is not difficult because it is based on the statement or theorem which has been already proved. For example the fundamental theorem of algebra and its corollary. Therefore, the statement "A corollary is a statement that can be proved using a theorem, but the proof is usually difficult." is false

Answer:

she can buy the rose bush and 29 packets of seeds. So i think X= 29

Step-by-step explanation:

Answer:

m is less than A apparently

Step-by-step explanation:

(A ∩ B)' is the complement of A ∩ B, or the set of all elements in the universal set U that do not belong to A ∩ B.

A ∩ B is the intersection of A and B, or the set of all elements common to both A and B.

We have

A = {q, s, u, w, y}

B = {q, s, y, z}

so that

A ∩ B = {q, s, y}

Then

(A ∩ B)' = {r, t, u, v, w, x, z}

which makes (c) the answer.

i really dont even know

Step-by-step explanation:

Answer:

Sorry if it’s to late but the answer is 56:)

Step-by-step explanation:

Answer:

[tex]a)\ x_1=-3i,\ x_2 =3i[/tex]

[tex]b)\ x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]

Step-by-step explanation:

Given equations:

[tex]a)\ x^2+19=10\\\\b)\ 4x^2+3=43[/tex]

A. x² + 19 = 10

Step 1: Subtract 19 from both sides.

[tex]\\\implies x^2+19-19=10-19\\\\\implies x^2=-9[/tex]

Imaginary number rule: For any positive real number "k", [tex]\sqrt{-k} = i\sqrt{k}[/tex]

Note: Two imaginary (complex) solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.

Step 2: Take the square root of both sides (positive and negative roots).

[tex]\\\implies \sqrt{x^2}=\sqrt{-9}\\\\\implies x=\pm\ i\sqrt{9}\\\\\implies x=\pm\ 3i[/tex]

Step 3: Separate the solutions.

[tex]\implies x_1=-3i,\ x_2 =3i[/tex]

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

B. 4x² + 3 = 43

Step 1: Subtract 43 from both sides.

[tex]\\\implies 4x^2++3-3=43-3\\\\\implies 4x^2=40[/tex]

Step 2: Divide both sides by 4.

[tex]\\\implies 4x^2=40\\\\\implies \dfrac{4x^2}4=\dfrac{40}{4}\\\\\implies x^2=10[/tex]

Step 3: Take the square root of both sides (positive and negative roots).

[tex]\\\implies \sqrt{x^2}=\sqrt{10}\\\\\implies x=\pm\ \sqrt{10}[/tex]

Step 4: Separate the solutions.

[tex]\implies x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]

Answer:

Axis of symmetry is 0

Step-by-step explanation:

Inequalities

Solve the inequality:

[tex]x^2-x\ge 6[/tex]

Subtracting 6:

[tex]x^2-x-6\ge 0[/tex]

Factoring:

(x-3)(x+2) ≥ 0

We have a product that must be greater or equal to 0. This can only happen if:

x - 3 ≥ 0  and x + 2 ≥ 0

Or:

x - 3 ≤ 0  and  x + 2 ≤ 0

The first couple of conditions yields to:

x ≥ 3 and x ≥ -2

Which lead to the solution

x ≥ 3       [1]

The second couple of conditions yields to:

x ≤ 3 and x ≤ -2

Which lead to the solution

x ≤ -2        [2]

The final solution is [1] or [2]:
