Jessica has four more hockey cards than one third the number of cards that David owns if Jessica has 12 hockey cards how many do es David have
2 answers:
We can use the equation <em>j=1/3(d)+4, </em> where j represents Jessica's cards and d represents David's cards. We already have the number of cards that Jssica has, so we can just solve the equation. 12=1/3(d)+4 simplified is 8=1/3(d) which is d=24 So David has 24 cards. :)
I believe the answer would be 24 work: 12-4=8 8x3=24

Answer: the answer is -6
2(n+5) = -2
2n + 10 = -2
2n = -2 - 10
2n = -12
2n *1/2 = -12 * 1/2 = -6
n = -6
F(x) = 2(x-3) + 4 F(-2) = 2(-2-3) + 4 F(-2) = 2(-5) + 4 F(-2) = -10 + 4 F(-2) = -6 Hope this helps
The answer is .5 meaning half (1/2) of the petals fell off.
9=5 -y/3 -5 3=-y/3 cross multiply 1=-y y=-1
First divide the coefficients:- -18 / -12 = 3/2 a^-2 / a^-4 = a^2 b^-5 / b^-6 = b so the expression simplifies to 3a^2b / 2
