Answer:
Step-by-step explanation:
5 + x - 12 = x- 7 (Add the 5 and -12 to simplify)
x - 7 = x - 7 (notice its the same on both sides of equal sign. Add 7 to both sides)
x = x
solution is all real numbers
Part B
5 - 4 - 12 = -4 - 7
-11 = -11
5 + 0 - 12 = 0 - 7
-7 = -7
5 + 5 - 12 = 5 - 7
-2 = -2
Answer:
Step-by-step explanation:
There are many.
V = 5
X = 10
VI = 6
VIII = 8
IX = 9
L = 50
C = 100
D = 500
C = 1000
Answer:
The plant grows 1 cm every day is the incorrect statement
Step-by-step explanation:
The graph shows that for every 10 days the plant grows 1 cm
10/2 = 5
so in 5 days the plant would grow half of what it does in 10 days so 1/2 or 0.5 cm
10/10 = 1
so in 1 day the plant would grow a tenth of what it does in 10 days so 1/10 or 0.1 cm
Answer is c. -2 (cannot be in the solution set of w/-2)
because.
a) -1/-2 = 1/2 and 1/2 < 1
b) 1/-2 = -1/2 and -1/2 <1
d) 2/-2 = -1 and -1 <1
but
c) -2/-2 = 1 and 1 = 1
