6j + 1/3n = 134...multiply by 3....18j + n = 402
1/3j + n = 31....multiply by 3....j + 3n = 93
the multiplying by 3 is optional...I just did it because it is easier to work with equations when there are no fractions.
18j + n = 402....multiply by -3
j + 3n = 93
----------------
-54j - 3n = - 1206 (result of multiplying by -3)
j + 3n = 93
----------------add
-53j = - 1113
j = -1113/-53
j = 21
j + 3n = 93
21 + 3n = 93
3n = 93 - 21
3n = 72
n = 72/3
n = 24
so Jasons collection (j) consists of 21 books and Nathans collection (n) consists of 24 books
Answer:
c = 2
Step-by-step explanation:
Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions
~
First, subtract 6 from both sides of the equation:
9c + 6 (-6) = 24 (-6)
9c = 24 - 6
9c = 18
Next, divide 9 from both sides of the equation:
(9c)/9 = (18)/9
c = 18/9
c = 2
c = 2 is your answer.
~
F(0)= -4(0)+9
F(0)= 0+9
F(0)=9
7x + 3 is the final answer
Answer:
±16
Step-by-step explanation:
the square root of 256 is positive or negative 16! (if it only lets you put one answer, put positive 16).
