Ten inches is only a fraction of a foot. There will be no feet involved. To make it into a fraction, put 10 inches over the amount of inches in one foot (12 inches).
10/12 is the fraction that needs to be reduced. Both numbers can be reduced by the number 2 so final fraction is 5/6.
What you do is move the equation around so the 12 -4.5x would now turn into y=-4.5x+12
Answer:
a. False. A constant is a number on it's own, and 5 would be the coefficient of x. 8 would be the constant.
b. False. -6.5 would be the constant, since it's on its own. But actually, x would be carrying on a coefficient of 1. Letters are variables, not constants.
c. True.
245 y = 1,470
Divide each side by 245 :
<em>y = 6</em>
Did I go too fast for you ?
X+n-8
I think that's right.
I hope this helps.
