Answer:
x =
or 
Step-by-step explanation:
First, combine like terms. Like terms are terms with the same amount of the same variable.
(2x + 3x) - 7 = 42
5x - 7 = 42
Isolate the variable, x. 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, add 7 to both sides of the equation:
5x - 7 (+ 7) = 42 (+ 7)
5x = 42 + 7
5x = 49
Next, divide 5 from both sides of the equation:
(5x)/5 = (49)/5
x = 49/5
x = 9.8
Hi there!

Therefore, there is 18 quarters in 4 1/2.
I think its 210 because there are 7 letters and 3 vowels so the permutation would be 7 P 3.
Answer:
positive 3/2
