what is the answer to this r/19=-15 (answer)
r/19=-15 multiuply each side by 19 19*(r/19)=-15*19 r=-285
r/19=-15 multiuply each side by 19 19*(r/19)=-15*19 r=-285
8*16=128- that is all.
that is right
30*x+5=8 30x=3 x=,io so, 30 dimes and 6 =8
l=2w-3 p=414 2l+2w=414 2*(2w-3)+2w=414 4w=-6+2w=414 6w=420 w=70 l = 2*70-3=137
(x+13)*3=7x-9 3x+39=7x-9 -4x=-48 x=12
50+50*13.99+450*12.99= $6595
okay - lets break that out = 100 3/2= = 100 1/2 X 3 = 10*10 *10 = 1000
OKay, solve the equation as follows: 1. Add -2 +1 = -1 2. Add +1 to both sides - so you get -2+x>0 3. Add 2 to both sides and this solves the problem x>2
