Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

<h3><u>Correcte</u><u>d Question</u><u>:</u><u> </u></h3>
Solve for x :
4 - (2x + 4) = 5
1) x = -10
2) x = 5/2
3) x = 1/2
4) x = 6
<h3><u>Answer</u><u>:</u><u> </u></h3>
➛ 4 - 2x + 4 = 5
➛ 2x + 4 - 4 = 5
➛ 2x + 0 = 5
➛ 2x = 5
➛ x = 5/2
Thus, The value of x is <u>5/2</u><u>.</u><u> </u>
Answer:
The first blank is: 26
The second blank is: 17
The third blank is: 31 - n
Step-by-step explanation:
So basically each row should add up to 31. So for every number they give you (doesn't matter which color ball), you need to subtract it from 31.
That's why for the first blank, 31 - 5 is 26
second blank, 31 - 14 is 17
and so on....
so the resulting function would be 31 - n
n being a random number that is given to you
3/8 = 1/8 +1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 +1 + 1/8 = 8/8 + 8/8 + 1/8.
i hope i helped.
