Answer:
A: 1(2x - 1) + 5(4x + 2)
B: Simplify above and divide by 0.5
C: (21 x 3) + (4 x 5 +2)
Step-by-step explanation:
2000. Because if you add the 2 it will make 1200, 2+8 is 10 so you carry the 1, and 3+9 is 12 then you add the 1 you got from 10 and you have 13. then you add 1+1 and get 2 and add the 1 you got from 13 so there you have it.
Answer:
15
Step-by-step explanation:
Let n represent the number of twelvths in 5/4.
Expressed symbolically, this is n/12 = 5/4.
The LCD is 12. Multiply numerator and denominator of 5/4 by 3, obtaining:
n/12 = 15/12. Then n = 15.
There are 15 twelves in 5/4.
The radius of Earth is 6.3781 Kilometers
I just used processes of elimination. the answer is 50
