Answer:
hotdog $1, and hamburger $2
Step-by-step explanation:
D-is hot dogs, H-hamburgers
7D +4H = 15
4D +7H = 18
we got 2 equations with 2 unknown so we can solve
7D +4H = 15 multiply by 7
4D +7H = 18 multiply by -4
49D +28H = 105
-16D -28H = -72 add the two equations
33D= 33 so D=$1
go back to the first equation:
7*1 +4H =15 gives us 4H = 15-7; 4H = 8 so H= $2
Answer:
20
Step-by-step explanation:
Most likely this is a triangle triangle have 180 always
Kevin=k
Daniel=d
k=4d
k=d+6
4d=d+6
4d-d=6
3d=6
d=2
k=d+6
k=2+6
k=8
Daniel is 2
Kevin is 8
F(x) slope is bigger than g(x) as 6>2
G(x) because 6 is the slope of g(x) and -6 is the slope of f(x)
