Step-by-step explanation:

Step 1: Define

3.2(x - 1) + 1.5(2x - 2) = 7.44

Step 2: Solve for x

Plug in x into the original equation to verify it's a solution.

Here we see that 7.44 does indeed equal 7.44

∴ x = 2.2 is the solution to the equation.

the answer

b. they are parallel and will never intersect.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
