Answer:
x = 6
Step-by-step explanation:
Step 1: Write equation
150 - x - 2x = 120 + 2x
Step 2: Solve for <em>x</em>
- Combine like terms: 150 - 3x = 120 + 2x
- Add 3x to both sides: 150 = 120 + 5x
- Subtract 120 on both sides: 30 = 5x
- Divide both sides by 5: 6 = x
- Rewrite: x = 6
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
150 - 6 - 2(6) = 120 + 2(6)
144 - 12 = 120 + 12
132 = 132
Answer:
P(select green sock) = 1/8
Step-by-step explanation:
If the probability of selecting a white sock is 1/4, then we know there are 2 white socks: 1/4 has the same value as 2 out of 8.
Similarly, we can determine the number of yellow socks: 5/8 is equivalent to 5 out of 8.
Thus, 2 socks are white; 5 are yellow; and the last (the 8th) sock is green.
P(select green sock) = 1/8
The area is 396 square inches.
