Answer:

34 652 is the number.Know find the ten place which is the (5).

Answer:

Let's define the variables:

x = number of hot dogs he buys

y = number of cheeseburgers he buys.

Each hot dog costs $2, then the price of x hotdogs is:

x*$2

Each cheeseburger costs $3, then the price of y cheeseburgers is:

y*$3

The total price is:

x*$2 + y*$3

And we want to find an equation to see how much he can buy for exactly $10, then we have:

x*$2 + y*$3 = $10

Or, if he can use $10 or less than $10, the inequality would be:

$0 ≤ x*$2 + y*$3 ≤ $10

Answer:

option A) Agree, because the solutions are the same is correct.

Step-by-step explanation:

FIRST SYSTEM

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

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

solving the system

[tex]\begin{bmatrix}6x+y=2\\ -x-y=-3\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}-x-y=-3\mathrm{\:by\:}6\:\mathrm{:}\:\quad \:-6x-6y=-18[/tex]

[tex]\begin{bmatrix}6x+y=2\\ -6x-6y=-18\end{bmatrix}[/tex]

adding the equation

[tex]-6x-6y=-18[/tex]

[tex]+[/tex]

[tex]\underline{6x+y=2}[/tex]

[tex]-5y=-16[/tex]

so the system becomes

[tex]\begin{bmatrix}6x+y=2\\ -5y=-16\end{bmatrix}[/tex]

solve -5y for y

[tex]-5y=-16[/tex]

Divide both sides by -5

[tex]\frac{-5y}{-5}=\frac{-16}{-5}[/tex]

simplify

[tex]y=\frac{16}{5}[/tex]

[tex]\mathrm{For\:}6x+y=2\mathrm{\:plug\:in\:}y=\frac{16}{5}[/tex]

[tex]6x+\frac{16}{5}=2[/tex]

subtract 16/5 from both sides

[tex]6x+\frac{16}{5}-\frac{16}{5}=2-\frac{16}{5}[/tex]

[tex]6x=-\frac{6}{5}[/tex]

Divide both sides by 6

[tex]\frac{6x}{6}=\frac{-\frac{6}{5}}{6}[/tex]

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

Therefore, the solution to the FIRST SYSTEM is:

[tex]x=-\frac{1}{5},\:y=\frac{16}{5}[/tex]

SECOND SYSTEM

[tex]2x-3y = -10[/tex]

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

solving the system

[tex]\begin{bmatrix}2x-3y=-10\\ -x-y=-3\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}-x-y=-3\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-2x-2y=-6[/tex]

[tex]\begin{bmatrix}2x-3y=-10\\ -2x-2y=-6\end{bmatrix}[/tex]

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

[tex]+[/tex]

[tex]\underline{2x-3y=-10}[/tex]

[tex]-5y=-16[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}2x-3y=-10\\ -5y=-16\end{bmatrix}[/tex]

solve -5y for y

[tex]-5y=-16[/tex]

Divide both sides by -5

[tex]\frac{-5y}{-5}=\frac{-16}{-5}[/tex]

Simplify

[tex]y=\frac{16}{5}[/tex]

[tex]\mathrm{For\:}2x-3y=-10\mathrm{\:plug\:in\:}y=\frac{16}{5}[/tex]

[tex]2x-3\cdot \frac{16}{5}=-10[/tex]

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

Divide both sides by 2

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

Simplify

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

Therefore, the solution to the SECOND SYSTEM is:

[tex]x=-\frac{1}{5},\:y=\frac{16}{5}[/tex]

Conclusion:

As both systems of equations have the same solution.

Therefore, we conclude that Albert is right when says that the two systems of equations shown have the same solutions.

Hence, option A) Agree, because the solutions are the same is correct.

Answer:

14

Step-by-step explanation:

In 70/5 the dividend is 70 and the divisor is 5 .

First draw a number line from zero to the dividend.

Next, starting from 70 skip count by the divisor backwards till you reach 0.

The numbers of skips taken to reach zero is the result, also called, the quotient. In this case there are 14 skips .

Answer:

|x − 40| ≤ 7.5.

Step-by-step explanation:

The absolute value inequality |x − 40| ≤ y models the relationship between the acceptable weights of the suitcase and the amount it can vary.

If the suitcase weight can vary up to 7.5 pounds, then 7.5 can be substituted for y in the inequality:

|x − 40| ≤ 7.5.

This inequality can be used to find the range of acceptable weights of the suitcase.

Answer: 0.75. It's pretty obvious.

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

14+5x=−5(x−8)+4

14+5x=(−5)(x)+(−5)(−8)+4(Distribute)

14+5x=−5x+40+4

5x+14=(−5x)+(40+4)(Combine Like Terms)

5x+14=−5x+44

5x+14=−5x+44

Step 2: Add 5x to both sides.

5x+14+5x=−5x+44+5x

10x+14=44

Step 3: Subtract 14 from both sides.

10x+14−14=44−14

10x=30

Step 4: Divide both sides by 10.

10x/10 = 30/10

Answer:

x=3

Step-by-step explanation:

1. Rearrange terms

2. Distribute

3. Add the numbers

4. Subtract14 from both sides of the equation

Answer: (B) x^3

Explanation:

If you compare the graphs of

all on the interval -1 < x < 0, you'll find that y = x^3 is the smallest when x = -1

Squaring a negative number leads to a positive result, and similarly that happens with x^4 as well. This is because x^4 = (x^2)^2.

Plugging x = -1 into x^3 leads to y = -1 as a result.

Answer:

The missing value is 1

Step-by-step explanation:

We need to find the missing value, if the expression is equal to 12.

The given expression is: [tex]\frac{(8+?)}{\frac{3}{4} }[/tex]

and the expression is equal to 12, so we can write: [tex]\frac{(8+?)}{\frac{3}{4} } = 12[/tex]

Solving to find the missing term

[tex]\frac{(8+?)}{\frac{3}{4} } = 12\\(8+?) \div (\frac{3}{4})=12\\Converting\:division\:sign\:to\:multiplication\:and\:reciprocating\:the\:term\\ (8+?) \times (\frac{4}{3})=12\\8+?=12 \times \frac{3}{4}\\8+?=3 \times 3\\8+? = 9\\? = 9-8\\?=1[/tex]

So, the missing value is 1

Answer:

Yes, (3x + 2)(x + 1).

Step-by-step explanation:

1. You're going to need to find two numbers that add to equal 5. The best option here is 2 and 3.

2. Separate the equation into groups. Right now, you have [tex]3x^2 + 5x + 2[/tex]. To separate into groups, you write  [tex](3x^2 + 3x) + (2x + 2)[/tex].

3. Now, from the first set of parenthesis, you can factor out 3x. This gets you [tex]3x(x + 1)[/tex]. The second set of parenthesis you can factor out the 2. This gets you [tex]2(x+1).[/tex]

4. Now, you see that you have (3x + 2)(x + 1).

Hope this helps! Let me know if you have any questions.

Answer:

The cat weighs 2860 g more

Step-by-step explanation:

Convert the cats weight (3.1 kg) to grams.

Subtract the cats weight and the parakeets weight to find total.

In this case 3100 g (cats weight) - 240 g (parakeets weight) = 2860 g

Answer:

  A) SQ is the geometric mean between the hypotenuse and the closest adjacent segment of the hypotenuse.

Step-by-step explanation:

In this geometry, all of the right triangles are similar. That means corresponding sides have the same ratio (are proportional).

Here, SQ is the hypotenuse of ΔSQT and the short side of ΔRQS.

Those two triangles are similar, so we can write ...

  (short side)/(hypotenuse) = QT/SQ = QS/RQ

In the above proportion, we have used the vertices in the same order they appear in the similarity statement (ΔSQT ~ ΔRQS). Of course, the names can have the vertices reversed:

  QT/SQ = SQ/QR . . . . . QS = SQ, RQ = QR

__

When this is rewritten to solve for SQ, we get ...

  SQ² = QR·QT

  SQ = √(QR·QT) . . . . SQ (short side) is the geometric mean of the hypotenuse and the short segment.

Answer:

The specificity of this test is expressed as:________

70%.

Step-by-step explanation:

a) Data and Calculations:

TEST RESULTS       Disease Present    Disease Absent      Total

Positive for Factor X      40                            60                    100

Negative for Factor X    10                            140                   150

Total                              50                           200                  250

Negative for X and Disease Absent = 140/200 * 100

= 0.7 * 100

= 70%

b) The specificity refers to the percentage of people who test negative for a specific disease among a group of people who do not have the disease. No test is 100% specific because some people who do not have the disease X will test positive for it (false positive).  Therefore, we are testing for the true negative, that the 140 people who tested out of the 200 people who do not have the disease.

C: p < 0.01

Step-by-step explanation:

We are given;

Spearman rank Correlation Coefficient: rs = 0.53

sample size: n = 13 pairs

Now, from the table attached, tracing n = 13 and locating a corresponding value of rs = 0.53 which falls in between 0.484 and 0.56. Thus, we can see that p is greater than the nominal significance value of 0.05 but less than 0.01.

Thus, correct answer is p < 0.01
