5 + x / 9 = 3 subtract 5 from both sides of the equation
x/ 9 = - 2 multiply both sides by 9
x = -18
Yes, that is correct....subtract the smaller from the larger area to get the area betweem them.
Put in x = -6 into the equation result -1110
x = number of bills in his wallet
The values are as follows:
1/5 (x ) ( 10 ) + (2/5 x -3) (5) + ( 2/5 x +3) (2) = 159
2x + 2x - 15 + 4/5 x +6 = 159
x = 35 bills
2/5 (35) + 3 = 17 two dollar bills
You are right ! I got it backwards !
I am unable to edit it now ..... hopefully your answer will be read ! THANX, JKP !
Originally n = 3 h
then n+4 = 2 ( h+3 ) sub in the first equation
3h + 4 = 2 ( h +3)
h = 2 2 + 3 = 5 apples in the end for H
Just look at the he=ighest degree terms x^4 - 2x^4 = - x^4 Degree remains 4
(r - 3)/sqrt(r) = -2*sqrt(r). Multily both sides of the equation by sqrt r
r-3 = -2r
3r = 3
r = 1
1.13 km ...... From B
Law of sines
.6 / sin20 = f /sin 40
1) You'll need to commit some of these values to memory sin and cos of: 0 30 45 60 90
sin 60 = sqrt(3) / 2 tan 45 = 1 cos 120 = - 1/2 sin 150 = 1/2
