Algebra pyramid please answer !! be the first to be marked as a brainliest .

Answer:

The first pyramid:

63x

39x 24x

23x 16x 8x

The second pyramid:

162x

82x 80x

4x 78x 2x

The third pyramid:

12a+2b

9a+b 3a+b

9a b 3a

The fourth pyramid:

-19a

-5a -14a

3a -8a -6a

Step-by-step explanation:

All that an alegbra pyramid is is adding the two terms below it.

So you can see how I added the terms that lied below each number, such as in number 1: I added 23x and 16x to get me 39x, and I added 16x and 8x to get me 24.

Hope this helped!

3 + 1/2 (3-x) < -7<br><br> Show work please!

<em><u>x>23 is the correct answer.</u></em> First you had to subtract by 3 from both sides of equation. And it gave us, $3+\frac{1}{2}(3-x)-3$ . Then simplify, and it gave us, $\frac{1}{2}(3-x)$ . Next, multiply by 2 from both sides of equation, and it gave us, $2*\frac{1}{2}(3-x)$ . Then simplify, and it gave us, $3-x$ . You can also subtract by 3 from both sides of equation, and it gave us, $3-x-3$ . Then simplify, and it gave us, $-x$ . Multiply by -1 from both sides of equation, and it gave us, $(-x)(-1)>(-23)(-1)$ . Finally simplify, and it gave us the answer is<u><em> x>23 is the right answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

2.2.PS-141You are running a fuel economy study. One of the cars you find is blue. It can travel 39miles on21241 gallons of gasol

svetoff [14.1K]

<h2>Answer:</h2> $\begin{gathered} \text{Unit rate of blue car = 31}\frac{3}{5}mi\text{ per gallon} \\ \text{Unit rate of red car = 28 mi per gallon} \end{gathered}$

The blue car has traveled the greater distance on one gallon of gasoline

<h2>Explanation:</h2>

The formula for calculating the unit rate is expressed as shown:

$\text{Rate = }\frac{Distance}{\text{number of gallons}}$

For the blue car

Distance = 39.5miles

Gallons of gasoline = 1.25 gallons

Get the unit rate:

$\begin{gathered} \text{Unit rate = }\frac{39.5}{1.25} \\ \text{Unit rate = 3}1.6\text{ }miles\text{ per gallon} \end{gathered}$

The unit rate of the blue car as a mixed fraction is 31 3/5 miles per gallon

For the red car

Distance traveled = 22.4 miles

Gallons of gasoline = 0.8 gallons of gasoline

Get the unit rate of the red car;

$\begin{gathered} Unit\text{ rate = }\frac{22.4}{0.8} \\ \text{Unit rate = }28\text{miles per gallon} \end{gathered}$

From the unit rates, we can see that the blue car has traveled the greater distance on one gallon of gasoline since its unit rate is greater than that of the red car.

Please help me thanks :)

Answer:

Step-by-step explanation:

To sovle this we must combine the numbers togther and the variables togther.

We have:

8c+6-3c-2

Lets take out the c's and combine them:

8c -3c

Now lets take out the numbers:

6-2

Now lets put these back together and we get the expression:

5c+4

This looks like A.

Hope this helps! :D
