Answer:

u = -3

Step-by-step explanation:

-9 - 4u = -u

    +4  = +4

Add 4u to both sides.

-9 = 3u

Divide both sides by 3

-9/3 = 3/3

-3 = u

Answer: The variable u  is equal to -3 for this equation.

Step-by-step explanation:

To solve this variable equation, you will need to follow these steps:

Rewrite the equation, moving 9 to the other side, adding it on both sides, and simplify

-4u = -u + 9

After that, move u to the other side of the equation, also adding it on both sides and simplify

-3u = 9

Then divide both sides by -3, simplify it one last time and you will get your answer!

-3

Therefore, the answer to this equation would be equal to negative three or -3. Hope this helps!

Answer:

It will take 100 minutes for Brenna's class to walk 5 miles.

Step-by-step explanation:

If it takes 20 minutes for Brenna's class to walk 1 mile, we then multiply both of the numbers by 5 for 5 miles.

To find f(f^(-1)(9)), we need to first find f^(-1)(9), the inverse of f(9).

Given that f(4) = 9, we know that f^(-1)(9) is equal to 4.

Therefore, f(f^(-1)(9)) is equivalent to f(4).

Given that f(4) = 9 according to the problem statement, we can conclude that f(f^(-1)(9)) = 9.

Step-by-step explanation:

Answer: $849.98 + 6.5% of $849.98 = $849.98 (1 + 0.065) = 1.065*849.98 = $905.2287. The total cost of the laptop with sales tax included is $905.2287.

Answer: 873.59

9.75/100*795.98=77.61

795.98+77.61=873.59

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Hello!

Answer:

12 cm, 12 cm, 10 cm.

Step-by-step explanation:

Given:

Perimeter, or P = 34 cm

Ratio of sides = 6 : 6 : 5

To find the length of each side, we can use a variable in the ratio to find the perimeter:

34 = 6x + 6x + 5x

Combine like terms:

34 = 17x

Solve for x:

34/17 = 17x/17; x = 2

Plug in this value of "x" into each expression for the side-lengths:

6(2) = 12 cm

6(2) = 12 cm

5(2) = 10 cm

Therefore, the lengths of each side of the triangle are 12 cm, 12 cm, 10 cm.

Hope this helped you! :)

Answer:

12, 12 and 10 cm.

Step-by-step explanation:

6 + 6 + 5 = 17

So one side = 6/17 * 34 = 12 cm

One other side is also 12 cm

The third side = 5/17 * 34 = 10 cm.

Step-by-step explanation:

The melting point of zinc is (420-98) = 322 degrees Celsius hotter than the melting point of sodium.

The temperature of Venus is (480 - (-230)) = 710 degrees Celsius warmer than the temperature on Pluto.

The difference between the melting points of aluminum and copper is (1083 - 659) = 424 degrees Celsius.

The boiling point of water is (212 - (-440)) = 652 degrees Fahrenheit hotter than the boiling point of propane.

The difference between the freezing points of unleaded gas and water is (-150 - 32) = -182 degrees Fahrenheit.

The difference in temperature between the day side and dark side of Mercury is (400 - (-180)) = 580 degrees Celsius.

Hydrogen freezes first because it has a lower freezing point (-252.80C). To freeze oxygen, the temperature needs to be lowered to (-218.79C).

The temperature dropped (10 - (-9)) = 19 degrees Celsius.

The drop in temperature from day to night on the moon is (260 - (-280)) = 540 degrees Fahrenheit.

The melting point of gold is (1946 - 1762) = 174 degrees Fahrenheit hotter than the melting point of silver.

Answer: The melting point Zinc is 420 - 98, which equals 322 degrees. The Celsius is hotter than the melting point of sodium.

The temperature of Venus is 480 - (-230), which equals 710 degrees. The Celsius is warmer than the temperature on Pluto.

The difference between the two melting points of Aluminum and Copper is 1083 - 659, which equals 424 degrees Celsius.

The boiling point of Water is 212 - (-440), which equals 652 degrees. The temperature in Fahrenheit is hotter than the boiling point of Propane.

The difference between the two freezing points of unleaded gas and water is -150 - 32, which equals -182 degrees Fahrenheit.

The difference in the temperatures between the day and dark side of the planet Mercury is 400 - (-180), which equals 580 degrees Celsius.

Hydrogen freezes first, because it is a lower freezing point at -252.80C. Freezing oxygen, the temperature needs to be lower than -252.80C to about -218.79C.

The temperature drops 10 - (-9), which equals 19 degrees Celsius.

The drop in the temperatures from day to night on the moon is 260 - (-280), which equals 540 degrees Fahrenheit.

The melting point of Gold is 1946 - 1762, which equals 174 degrees. The temperature in Fahrenheit is hotter than the melting point of Silver.

Answer:

The required number of batches of cookies corresponding to the 45 ounces is 7.5 batches.

Step-by-step explanation:

Given that,

The number of ounces of chocolate chips per batch of cookies can be represented with the equation y = 6x, where y represents ounces of chocolate chips and x represents batches of cookies.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,

Given proportionality,

y = 6x

Put y = 45

x = 45 / 6

x = 7.5

Thus, the required number of batches of cookies corresponding to the 45 ounces is 7.5 batches.

Answer:The required number of batches of cookies corresponding to the 45 ounces is 7.5 batches. Option C is correct.
