Algebra basically consists of mathematical operations, but using letters. To solve the exercises you only have to say that is the variable X

for Example: 4x= 8
                       x= 8 divide by 4
                       x= 2

In particular to the equations above, your goal is to find the value of x.

Step 1: isolate the variable (in this case,x).
Isolating the variable makes you narrow down what you are solving for.

Step 2: solve for the variable.
You can solve for the variable by making x alone (meaning with no coefficient).

If you have any questions on how you can do these while it still being mathematically legal, let me know and I will help.

Part A: Find a rational number that is between 5.2 and 5.5. Explain why it is rational. (2 points) Part B: Find an irrational nu
Ulleksa [173]
The answer 
<span>a rational number that is between 5.2 and 5.5
first, </span><span>a rational number  is a decimal number that the number after the dot can be ended. for example
1/2 = 0.5 is rational, 2 is rational because 2 = 2. 0, 

so a rational number </span>between 5.2 and 5.5 can be 525 /100
because this rational number can be written as 525 /100 = 5.25
and 5.2 less than 5.25 less than 5.5

an irrational number  is a decimal number that the number after the dot cannot be ended. for example  1/3 = 0.3333333333......

so so an irrational number between 5.2 and 5.5 can be √30
because √30 can be written as √30 = 5,477225575051661134569........

and 5.2 less than 5.47 less than 5.5

Match the solid figure to the appropriate formula.
AlekseyPX

1. L \cdot A=\pi r l        -       Cone

2. V=\frac{4}{3} \pi r^{3}         -        Sphere

3. T \cdot A=2 \pi r h+2 \pi r^{2} - Cylinder

4. V=\frac{1}{3} B h         -        Pyramid

5. L . A=p h         -        Prism

Solution:

1. L \cdot A=\pi r l

Lateral surface area of cone = \pi r l

where r is the radius of the cone and l is the slant height of the cone.

2. V=\frac{4}{3} \pi r^{3}

Volume of sphere = \frac{4}{3} \pi r^{3}

where r is the radius of the sphere.

3. T \cdot A=2 \pi r h+2 \pi r^{2}

Total surface area of cylinder = 2 \pi r h+2 \pi r^{2}

where r is the radius of the cylinder and h is the height of the cylinder.

4. V=\frac{1}{3} B h

Volume of pyramid = \frac{1}{3} B h

where B is the base area of the pyramid and h is the height of the pyramid.

5. L . A=p h

Lateral surface area of prism = p h

where p is the perimeter of the base and h is the height of the prism.
