39.50-23.76-2.57-1.49=11.68
take the sales and subtract the expenses
(a)
(b)we have 4 terms in this expression.
(c)+12 is the leading coefficient in
(d) constant is -45
Y - 4.5 = 12.2
your solving for y which means your trying to get rid of 4.5 so that y can equal something. The opposite of -4.5 would be +4.5, so you would add 4.5 to both sides to get
y = 16.7
So your answer would be
A. Add 4.5
and also dont' say your stupid because all you need is a little explanation and you'll get it, its very easy you just need to take the time to practice :-)
You should use this app called photomath!! it will give you the answer to the equation and there is a show work option and if you press it, it will show the work for u :)
There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
