Answer:
B
Step-by-step explanation:
1/2x - 2 > 0
collect like terms
1/2x > 0 + 2
1/2x > 2
Divide both sides by 1/2
x > 2 divided by 1/2
inverse of 1/2 is 2/1
x > 2 times 2/1
x > 4
2+2-1 that's three quick maths.
Answer:
D. 1800
Step-by-step explanation:

30 because tener is 6 sides and you do 6 times 5 to get 30
