Answer:
Eli
Step-by-step explanation:
Arjun: 20÷3=6.6666666667
6.6666666667mL of chocolate syrup for every ounce of hot water.
Eli: 45÷6=7.5
7.5mL of chocolate syrup for every ounce of hot water
Conclusion: Eli has the hot cocoa with the most chocolate
39-(15z+48)/27=35
39-35=(15z+48)/27
4=(15z+48)/27
108=15z+48
108-48=15z
60=15z
z=60/15
z=4
X = 6 / tan(67)
x = 2.546
rounded to nearest tenth x = 2.5
Y= ax² -4x +3
-b/2a is x - coordinate of the vertex,
line of symmetry x=-2, x=-2 is a coordinate of the vertex also, because the line symmetry has vertex.
x= -b/2a
x= -2, b= -4
-2=-(-4)/2a
-2=4/2a
-2=2/a
a=2/(-2)=-1
a= - 1
Answer:
I think that it equals 1ab. Because 3ab - 9ab= -6ab + 7ab= 1ab
