Ok. Maybe states. That makes more sense.

you would divide each side by 7/8 to get the variable alone. once you solve 3 divided by 7/8, you should get what h is.

1. you would do length*width*height 2. 3 feet equal 1 yard so do 3 1/2*3 3. 24 hrs are in one day so you divide 624 by 24

convert to common denominators then add. 6/11 would become 78/143 and 2/13 becomes 22/143. add then reduce(if possible)

thanks a bunch!

is this supposed to be a slope-intercept form question?

if it is then: 9x-7y=-49 -7y=-9x-49 divide everything by 7 y=-1 7/25-49 hope that helps!
