One Half of a number +four =(is) three -(less) than quotien of five and a number :
1/2n+4=3−5/n Solve is :
X=-1 +- 3i
The answer is (12, 30)
you plug in 2x +6 for y and get x=12. then you plug 12 in for x and y equals 30
15% = .15
add 1.00 to include the original amount
9 *(1+0.15) = 10.35
so $10.35
B ) 6
Substitute 15 in the equation for x.
G=15-9
G=6
Set it up as a direct variation equation y/x=k where k is the constant of variation. We have values for y and x and have to find k. 18/5=k, so k=3.6. Now plug in the other given y value and use that k value to find x: y/11=3.6 or
y/11=18/5, whichever your book or teacher prefers.
