Answer:

  x > 56

Step-by-step explanation:

The place to begin is this: look at the given inequality to see where the variable is and what has been done to it.

Here, the variable is on the left. It is buried in an expression in parentheses and other stuff is added outside. If you were to evaluate this expression using the Order of Operations, the operations you would perform are ...

So, to solve for x, you can "undo" these operations in the reverse order.

  8 +1/3(8 -x) < -8 . . . . . given

  1/3(8 -x) < -16 . . . . . . . subtract 8 to undo addition of 8

  8 -x < -48 . . . . . . . . . . multiply by 3 to undo multiplication by 1/3

  8 < -48 +x . . . . . . . . . . add x to undo the subtraction of x

  56 < x . . . . . . . . . . . .  add 48 to undo the subtraction of 48

The solution is ...

  x > 56

_____

Additional comment

You can do anything you like to an equation or inequality, as long as you do the same thing to both sides. When we say "subtract 8" we mean "subtract 8 from both sides".

The only difference between solving equations and solving inequalities is that some operations will cause the order to be reversed. Chief among these is multiplication or division by a negative number. Consider ...

  1 < 2

  -1 > -2 . . . . multiply (or divide) by -1, reverses the order

Answer:

  n^3 -9n^2 +9n +7

Step-by-step explanation:

The attached shows the long division tableau. The "Hints" column shows how the quotient terms are developed, and how the expression is found that is subtracted from the dividend.

The overall form of this work matches that of numerical long division. The difference is that there are no carries from one power of n to another the way there is in numerical long division from one power of 10 to another. I find polynomial long division to be simpler.

Answer:

Angles 2 and 6 are congruent as corresponding angles

Angles 6 and 7 form a linear pair.

Angles 2 and 6 are congruent as corresponding angles; angles 6 and 7 form a linear pair thus 2 and 7 will be supplementary angles so option (B) will be correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In the given figure lines m and n is parallel.

So,

Angle 2 = Angle 6 (Congruent)

Now,

Angle 6 and 7 are on a straight line so they will be linear pairs.

∠2 + ∠3 = 180

∠6 + ∠7 = 180

So,

(∠2 + ∠3) + (∠6 + ∠7) = 360

(∠2 + ∠7) + (∠3 + ∠6) = 180 + 180

Each corresponding pair will be the same because of congruent.

So,

(∠2 + ∠7)  = 180

Hence "Angles 2 and 6 are congruent as corresponding angles; angles 6 and 7 form a linear pair thus 2 and 7 will be supplementary angles".

Step-by-step explanation:

First, find the square roots.

[tex]\sqrt{-16} =4i[/tex]

[tex]\sqrt{-64} =8i[/tex]

Remember: i stands for [tex]\sqrt{-1}[/tex]

Then use the FOIL method to multiply.

(3+4i)(6-8i)

18-24i+24i-32i²

i²= -1, so :

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Let c represent the amount of gallons used in the city and h represent the amount of gallons used on the highway.

Graham drove a total of 200 miles. Since his car gets 25 miles per gallons in the city and 30 miles per gallon on the highway:

[tex]\displaystyle 25c + 30 h = 200[/tex]

And he used a total of seven gallons. In other words:

[tex]c + h = 7[/tex]

This yields a system of equations:

[tex]\displaystyle \left\{ \begin{array}{l} 25c + 30h = 200 \\ c + h = 7\end{array}[/tex]

Since we want to determine the number of miles Graham drove in the city, we will solve for c using substitution. From the second equation, solve for h:

[tex]\displaystyle h = 7 - c[/tex]

Substitute:

[tex]\displaystyle 25 c + 30 ( 7 - c) = 200[/tex]

Solve for c:

[tex]\displaystyle \begin{aligned} 25c + (210 - 30c) &= 200 \\ -5c &= -10 \\ c &= 2\end{aligned}[/tex]

Therefore, Graham used a total of two gallons in the city.

Since his car gets 25 miles per gallon in the city, Graham drove a total of:

[tex]\displaystyle \frac{25 \text{ mi}}{\text{gal}} \cdot 2\text{ gal} = 50\text{ miles}[/tex]

Or 50 miles in the city.

In conclusion, our answer is B.

Step-by-step explanation:

Let

Gallon in city = x

Gallon in highway = y

25x + 30y = 200 (i)

x + y = 7 (ii)

Multiplying ii by 30

30(x + y) = 30(7)

30x + 30y = 210 (iii)

On subtracting

30x + 30y - 25x - 30y = 210 - 200

5x = 10

x = 10/5

x = 2

Distance covered = 50

Answer:

The highway fence cost $600.

Step-by-step explanation:

Since the highway fence is twice as cost as the one of the other 4 sides, this means that the highway fence = 2 normal fence.

Therefore, we use

$1800 / highway fence(2 normal fence) + 4 normal fence

$1800 / (2 + 4) = $300

This means that every normal fence cost $300.

Which then we get the highway fence is $600 because it costs double of the normal fence.

Answer:

for the third question it is 3:10

1. Test results indicate that a patient has cancer when, in fact, he does not is False statement.

2. The probability of drawing a Queen, placing it back in the deck, and drawing any face card is 2%.

3. The odds in favor of it raining are 3:7.

1. The example of a false positive is:

Test results indicate that a patient has cancer when, in fact, he does not.

2. To find the probability of drawing a Queen, placing it back in the deck, and drawing any face card, we multiply the probabilities together.

There are 4 Queens in a deck of 52 cards.

So the probability of drawing a Queen is 4/52 = 1/13.

There are 12 face cards (4 Kings, 4 Queens, and 4 Jacks) in a deck of 52 cards.

So, the probability of drawing a face card is 12/52 or 3/13.

Now, the probability of both events happening, multiply the probabilities:

= (1/13) * (3/13)

= 3/169.

= 0.01775

Now, Converting 3/169 to a percentage and rounding to the nearest whole number,  2%.

Therefore, the probability of drawing a Queen, placing it back in the deck, and drawing any face card is 2%.

3. Given that there is a 30% chance of rain.

So, the probability of rain is 30/100 or 3/10.

The probability of no rain is the complement of the probability of rain, which = 1 - 3/10

          = 7/10.

Therefore, the odds in favor of it raining are 3:7.
