Answer:
C. 3x
Step-by-step explanation:
The first two choices give 1 solution each.
The last choice gives an infinite number of solutions.
Choice C. gives no solution.
3x + 9 = 3x
Subtract 3x from both sides.
9 = 0
Since 9 = 0 is false, equation 3x + 9 = 3x has no solution.
Step-by-step explanation:
1) 15.5 X 13.2 = 204.6
2) 204.6 ÷ 2 = 102.3
The answer is 102.3

Given: 2.54cm = 1 inch
To find: 4 feet 8 inches in centimeters
If 1 inch is 2.45cm,
Divide 2.45 by 1
Then multiply it by 4.8
Final answer: 146.3cm in nearest tenth.
If Lana's age is L, her youngest sister is L/2 (or 0.5L) and the twins L-2. Add all these together (remember that there are two sisters who are L-2 years old):
0.5L + L-2 + L-2 + L = 45
Simplify the L's by adding them all together, we get:
3.5L - 2 - 2 = 45
3.5L - 4 = 45
Now add 4 to both sides:
3.5L = 49
Now divide both sides by 3.5
L = 49/3.5 = 14. Now we know that Laura is 14, so her youngest sister must be 7.
