Equation Form:
w x 2
19
Divide both sides by 2:
w
9.5
So, w must be equal to or greater than 9.5 for this equation to work.
I think it would be C because the equation is y=7x. y=7x is also equal to x=1/7y. If y=45.50, then you would have to divide y by 7, which would equal 6.5.
I have no clue but you could ask your teacher to help u with it no jk the answer is -7
