89x-7
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
Step 1: Write out equation
2 - 4x = 3x - 12
Step 2: Add 4x on both sides
2 - 4x + 4x = 3x + 4x - 12
2 = 7x - 12
Step 3: Add 12 on both sides
2 + 12 = 7x - 12 + 12
14 = 7x
Step 4: Divide both sides by 7
14/7 = 7x/7
2 = x
Step 5: Rewrite
x = 2

The probability that a U.S. household selected at random has a computer and has Internet access will be 0.72. The C and I are independent events. Then the correct option is B.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Approximately 80% of households in the United States have computers. Of those 80%, 90% have Internet access.
Then the probability that a U.S. household selected at random has a computer and has Internet access will be
P(C and I) = 0.80 × 0.90
P(C and I) = 0.72
Then the C and I are independent events.
Then the correct option is B.

100% = 50
10% = 5
5% = 2.5
15% = 7.5
50 - 7.5 = $42.50
