Answer:
y=3
Step-by-step explanation:
3x+2y=9
Let x =1
3*1+2y=9
3 +2y = 9
Subtract 3 from each side
3-3+2y=9-3
2y = 6
Divide each side by 2
2y/2 = 6/2
y =3
Answer:
The volume is 140 cm3. See the explanation below, please
Step-by-step explanation:
We use the formula:
Volume (V) = 4/3 pi r ^3
V= 4/3x 3, 14x (6,44/2)^3 = 139,8 cm3= 140 cm3
X=-6 and x=1/3 are both correct values so A and D
