Why is it important to understand how variables work, inequalities, and basic awareness of exponents before starting algebra?

Answers

Answer:

It is important because they are the basics of algebra. Almost every algebraic problem you will ever solve is based on these fundamental properties. In equations, we almost never know every part of it so we will need variables to substitute the unknown amount in an equation. Variables are used for basically every equation/problem in algebra. Inequalities are not as important as variables but are still really important. Inequalities are basically comparing numbers. And in algebra when they add variables into an inequality, the inequality will help lower the number of possible values of said variable. And exponents are just a basic operation in algebra. Just like learning addition and subtraction. It is like a quicker and less complicated way of multiplying numbers.

y = 1/2x + 4
x - y = 8
*Substitution

Answers

Answer:

y=16, x=24

Step-by-step explanation:

First simplify: x-(1/2x+4)=8

Isolate x for 1/2x-4=8

Add 4 to both sides:

1/2-4+4=8+4

Simplify :1/2=12

Multiply both sides by 2:

2*1/2x=12*2

Simplify:

x=24

Substitute x=24:

y=1/2*24+4

1/2*24+4=16

1/2*24=12

12+4

Add the numbers: 12+4=16

y=16

The solutions to the systems of equations are:

y=16,x=24

why do systems of nonlinear equations sometimes have more than one solution

Answers

Answer:

System has equal number of unknowns and equations.

Manipulation easily yielded expressions for 4 of the 7 unknowns.

However it seems that the remaining 3 unknowns x,y,z are not fixed by the equations. Different combinations (x0,y0,z0) seem possible without violating the system equations.

Is this possible, or did I most probably make a mistake in counting degrees of freedom?

6 A rectangular room is 2 m longer than it is
wide. Its perimeter is 70 m. If the width of
the room is w m, express its length in terms
of zo. Hence find the width of the room.

Answers

Answer:

W = 16.5 meters

Step-by-step explanation:

let w be the width and then the length is w+2

Perimeter = 70 = 2w + 2(w+2)

70 = 2w + 2w + 4

4w = 66

w = 16.5 meters

Answer:

2550.5

Step-by-step explanation:

We have a circle and are asked to find the area.

We know the diameter already, but the formula to find area requires a raidus, which is unknown to us yet.

To find radius, all you need to do is follow [tex]\frac{d}{2}[/tex]. D being diameter.

D = 57.

[tex]\frac{57}{2}= 28.5[/tex]

The radius is 28.5, now do the formula of area.

[tex]A = \pi *r^2[/tex]

[tex]A = \pi *28.5^2[/tex]

[tex]28.5^2[/tex]

[tex]812.25[/tex]

[tex]A=\pi *812.25[/tex]

[tex]A=3.14 * 812.25[/tex]

[tex]A = 2550.465[/tex]

Now we need to round to the nearest tenths, since 6 is the knowledge that we round up, round up.
