Answer:
x=-1, -6
Step-by-step explanation:
x^2+7x+6=0
factor
(x+1)(x+6)=0
x+1=0, x+6=0
x=0-1=-1
x=0-6=-6
Answer:
it is on the nearest tenth. The number on the other side of the dot are tenths
Answer:
The volume of the ball is 256 cm³
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for V
The volume is equal to the ratio of the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
6216/16 is the answer the mixed number is 388 1/2
Answer:
x = 115
z = 27
Step-by-step explanation:
x + 65 = 180 (same side interior angles)
x = 115
x = 3z +34 (alternate interior angles)
115 = 3z + 34
3z = 81
z = 27
