Why is it important to understand how variables work, inequalities, and basic awareness of exponents before starting algebra?
Answer:
well algebra is basically about variables.
This is because you're assigning an equation or a number to a letter.

Solve for X in the rectangle?
Answer:
x=6
Step-by-step explanation:
13x+12=90
13x=78
x=6
The value of x in the rectangle is 6.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given quadrilateral is a rectangle.
In rectangle each angle has 90 degrees.
So equate 13x+12 and 90 degrees to get x
13x+12=90
Subtract 12 from both sides
13x=90-12
13x=78
Divide both sides by 13
x=6
Hence, the value of x in the rectangle is 6.

-1 2/3 divided by (-2 1/5)
Answer:0.75757575757
Answer:
Fraction Form
25/33
Decimal Form
0.75
Step-by-step explanation:
First, convert the mixed fraction into an improper fraction, so it would look like:
-5/3 / (-11/5)
Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:
5/3 x 5/11
Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

Answer:
the second one
Step-by-step explanation:
in order for it to be a function the x values CANNOT repeat.
in answer a the x value -6 repeats so that cannot be a function
in answer b none of the x values repeat so its probably this one but lets check the other ones just in case
in answer c the x value 8 repeats so it cannot be this one
in answer d the x value -2 repeats so it cant be this one \
b is the only one that does have repeating x values therefore it is the second one

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

4t and t+t+t+t

If C = x2 + 8x + 3 and B = x – 8, find an expression that equals 3C + B in
standard form.
Answer: 3x^2 + 25x + 1
Step-by-step explanation:
3C + B
=> 3(x^2 + 8x + 3) + (x - 8)
=> 3x^2 + 24x + 9 + x - 8
=> 3x^2 + 25x + 1
3(7 – 2y) = 9
Please help. You have to solve it using distributive property. Thank you.
Answer:
3(7-2y)=9
Because there is no symbol between the 3 and the "(" we can tell that it wants you to multiply.
With the distributive property you must distribute the 3 within (7-2y)
To that you would multiply 7 by 3, and multiply -2y by 3. This would get you:
21-6y=9
To get y you must isolate it, the first step to isolate it is remove the number with no "y" next to it. Which is "21" Also for further problems your way, You should add/subtract/divide/multiple the number that does not have the same or even a variable as the variable you are trying to find to the other side.
In this case it would be subtracting 21 from the left side and subtracting it to the right side which would give us: 6y=-12
(Because there was already a number with no variable: "9" you will subtract 21 from 9 which is why you get -12).
Next you will further isolate the y by removing the -6. "-6y" means -6 multiplied by y. So you will divide -6 from the left side AND the right side.
-6y ÷ -6 = y ; -12 ÷ -6 = 2
y=2
More tips: When you are moving something to the other side always do the opposite to remove it from one side and move it to the other. Example: -12 + y = 5
You want to move the -12 to the right side. So you need to remove "-12" from the left side by ADDING 12 because -12 + 12 = 0.
Now you simply add it to the right.
Another example: 4y = 8
Because 4y is multiplication (4 times y) you must divide it from each side to isolate the y! : y=2
If you divide a number from the left side, you must also divide it from the right side. If you add a number on the left side, you must also add it on the right side. Same goes for subtraction and multiplication. Think like that!

So ya
