Answers
Answer:
A. The area of a rectangle is equal to all the areas of the small rectangles. The dimensions of the small rectangles are 2a, 3a, and 4a. If you add those areas up, 2a+3a+4a equals the area of the large rectangle.
B. The area of a rectangle equals the width and height. The height of the large rectangle is already shown in the picture, a. The width is seperated into three portions, 2, 3, and 4. To find the total width, add 2+3+4. Now, multiply the width by the height to calculate the area. (2+3+4)a

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.

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.

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?

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
