Answer:
incorrect
Step-by-step explanation:
the volume of a cube = s³ ( where s is the length of the side )
to find s take the cube root
s = = 3
since 3 × 3 × 3 = 27
2x+3=7
2x+3-3=7-3
Whenever moving a number to the other side you have to change the sign .
2x= 4
x=2
If a< c< b then a<c and c<b
Separate the equation into 2 separate ones and solve them:
X-9 < 4x +3
Subtract 3 from both sides:
X-12 < 4x
Subtract x from both sides:
-12< 3x
Divide both sides by 3:
X > -4
4x+3 < 27
Subtract 3 from both sides
4x < 24
Divide both sides by 4
X <6
Combine to get one inequality:
-4<x<6
You didn't provide answer choices, but since 0.4=4/10 is rational, adding any irrational value to it will produce and irrational sum.
An irrational number is any number which can not be expressed as a fraction of two integers.
It would be $44.8 I think
