Answer:
Apply the distributive property
2x+2(4)=2x+8
Multiply 2 by 4
2x+8=2x+8
Move all terms containing x to the left and subtract 2x
2x+8-2x=8
Combine the opposite terms
2x+8-2x
Subtract 2x from 2x
0+8=8
8=8
All real number
Step-by-step explanation:
A - age of Abigail
C - age of Cynthia
A = C + 8
A - 20 = 3 (C - 20)
A - 20 = 3C - 60
C + 8 - 20 = 3C - 60
C - 12 = 3C - 60 A = C + 8
2C = 48 A = 24 + 8
C = 24 years A = 32 years
Method A: If we count, we see that the answer is 31.
Method B: 19 - -12 = 31. We can even do -12 - 19 and we'll get the same answer: -31, and the absolute value of -31 is 31.
Both methods will give you the same answer.
Answer:
-3
Step-by-step explanation:
Point A is half way between -17 and 5. This is span has a total distance of 17 + 5 = 22. Half way is 11 units from -17 or 5. So -17 + 11 = -6.
Point B is halfway between A at -6 and 0. This is a distance of 6. So halfway is 3 units away at -3.
