Answer: In mathematics, a variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions
Step-by-step explanation:A symbol for a value we don't know yet. It is usually a letter like x or y.
Example: in x + 2 = 6, x is the variable.
Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.
The literal numbers like- x,y,z etc. are variables.
Eg - 4x - 7 = 5
Here in this example x is the variable.

Your grandparents give you $1000 for your tenth birthday to invest for your college education. You research some investment companies around town and find one that pays you 4.2% and compounds quarterly. If you leave the money in your account until your 18th birthday, how much money will you have? Show all your work.
Answer:
$ 13,968.90
Step-by-step explanation:
You are given the money at 10 years oldInvest it until you're 18, so that's 8 yearsThis is compound interest, so use the formula: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]A is the total amount with interestP is the principal or starting amount 10000 dollarsr is the rate (percentage): 4.2%, use the decimal form in the equationn is the number of times you are compounding; in this case, it is compounded quarterly. Quarterly means every quarter of a year or 3 months, so it is compounded 4 times a year, n is 4t is the time, so that's 8 years[tex]A=10000(1+\frac{0.042}{4})^{4\times8}= 13,968.90[/tex]What goes in the table?

What is the ratio of the corresponding side lengths?
4:9
4:2
26:26
4.5:2
Answer:
4:2
Step-by-step explanation:
Answer:
4 : 2
Step-by-step explanation:
We are given ΔABC ≅ ΔA'B'C'.
When two triangles are congruent, their corresponding sides and angles are congruent.
Since, the sides of the triangles are in relation,
AB = 2 × A'B' and side BC = 2 × B'C' i.e. 4 = 2 × 2 and 9 = 2 × 4.5.
Therefore, the ratio of the corresponding sides are given by 4 : 2 and 9 : 4.5 i.e. 2 : 1.
Since, the ratio of the corresponding sides comes out to be 2 : 1 = 4 : 2.
Hence, the ratio of the corresponding sides is 4 : 2.

A bag contains 5 yellow marbles,2 blue marbles, and 3 other marbles. If Jerome reaches into a bag without looking and picks a marble at random, what is the probability that it is blue? (Alegbra expression)
Answer:2/10
Step-by-step explanation:
Answer:
unlikely
Step-by-step explanation:
There are 10 marbles altogether, 5 are yellow, 2 are blue, and 3 are random.
There are 3 more yellow marbles than blue marbles.
There is 1 more random marble than blue marbles.
Therefore, it is unlikely Jerome will get a blue marble.

Ron is planning for the back-to-school rush at his store. Last year he estimated that he would need 168 notebooks, but he sold 200 notebooks. Explain how Ron can find the percent error of his estimate.
Answer:
First find the error by finding the difference between the estimate and exact value. Then find the absolute value of the error. Set up a ratio with the absolute error to the exact value. Divide to find the decimal and multiply by 100 to find the percent.
