A. [tex]2.3p - 10.1 = 6.4 - 4[/tex]
B. [tex]2.3p - 10.1 = 6.9p - 4[/tex]
C. [tex]230p - 1010 = 650p - 400 - p[/tex]
D. [tex]23p - 101 = 65p - 40 - p[/tex]
E. [tex]2.3p - 14.1 = 6.4p - 4[/tex]

Answer :

Final answer:

By using properties to rewrite the given equation 2.3p - 10.1 = 6.5p - 4 - 0.01p, it matches the most with option 'c' 230p - 1010 = 650p - 400 - p, on simplification and scaling.

Explanation:

The student asked to use properties to rewrite an equation to match the given 2.3p - 10.1 = 6.5p - 4 - 0.01p. Comparing it to the options, the one that matches, after rearranging is, c. 230p - 1010 = 650p - 400 - p. The other options either do not have the same structure or produce a different value for 'p'

Here's how we match to option 'c': Let's first simplify the original equation by combining like terms: 2.3p + 0.01p - 6.5p = 4 + 10.1. This further simplifies to -4.19p = 14.1. In option 'c', after simplifying we have: 230p - 1010 = 650p - 400 - p. Again by noticing that unit 'p' has become '1p', we can say that the equation -4.19p = 14.1 is equivalent to option 'c', but the scaling factor is 100. Hence, option 'c' is the correct choice.
