Question

( 35(2x+5) - 2x )

After the expression above is simplified, what is the coefficient of ( x ) expressed as a decimal?
a) 0.6
b) 0.4
c) 0.2
d) 0.8

Answer 1

Upon simplifying the expression (35(2x+5) - 2x), the coefficient of x is 68, which is not listed in the provided options. This discrepancy suggests there might be an error in the question as presented.

Step-by-step explanation:

To find the coefficient of x after the expression (35(2x+5) - 2x) is simplified, we first distribute the 35 inside the parenthesis and then combine like terms:

35(2x) + 35(5) - 2x

70x + 175 - 2x

Now, we combine the x terms: 70x - 2x which gives us 68x. Thus, the coefficient of x is 68. To express this as a decimal, we simply have the number 68.0, which isn't in the list of provided answers and possibly indicates a mistake or misprint in the question. Since none of the provided options (0.6, 0.4, 0.2, 0.8) are correct, the question may need to be revisited for accuracy.
