Answers:
16. 6-x= 10
move +6 to the other side
sign changes from +6 to -6
6-6-x= 10-6
-x= 4
Mutiply both sides by -1
(-1)(-x)= (-1)(4)
x= -4
17. 4a+3= -9
move +3 to the other side
sign changes from +3 to -3
4a+3-3= -9-3
4a= -12
divide both sides by 4
4a/4= -12/4
a= -3
Move it to half way to the other side the way a clock moves.
10% off of 199.99 is 179.99
100% - 10% = 90% The 90% is how much you are going to pay.
90% into decimal form is 0.9
So you can do 199.99 x 0.9 = $179.99
The surface of the water is 0 feet. So 10 feet down means it is 0 - 10, or -10 feet as its final position.
I think you meant to write
3/4W = 9
to get rid of the denominator, multiply both sides by the denominator.
3W = 36
now divide both sides by 3
W = 12
the answer is 12 ounces.
