Answer:

x=18

Step-by-step explanation:

the result of 12 added to the difference of half a number and 3 is 45.

that looks something like this

12+\frac{1}{2}x= 45

which can be solved as such

\frac{1}{1} x+(12-3)=45\\\frac{1}{2}x+9=45\\\frac{1}{2}x=45-9\\ \frac{1}{2}x=36\\\frac{2}{1}*\frac{1}{2}x=36*\frac{2}{1} \\  x=36*2\\x=72

Contains the origin and is parallel to the line 8x − 3y = 3
Licemer1 [7]

Answer:

y=(8/3)x

Step-by-step explanation:

First, we make 8x-3y=3 into the form y=mx+b

3y=8x-3

y=(8/3)x-1

For an equation to be parallel to this equation, the slope must be the same, so the new equation will be:

y=(8/3)x+b

We know that (0,0) is a point in this line. We plug (0,0) into the equation to find b:

0=(8/3)*0+b

b=0

y=(8/3)x
