▹ Answer
<em>x = -7</em>
▹ Step-by-Step Explanation
-3x - 4(4x - 8) = 3(-8x - 1)
<u>Distribute</u>
-3x - 16x + 32 = -24x - 3
<u>Collect like terms</u>
-19x + 32 = -24x - 3
<u>Move variable to the left and change the sign</u>
-19x + 24x + 32 = -3
<u>Collect like terms</u>
5x = -3 - 32
<u>Calculate</u>
5x = -35
<u>Final Answer</u>
x = -7
Hope this helps!

Zeroooo solutions bc i did it earlier
If 2 gallons of oil are used a day, than he will need 60 gallons of oil, because 30x2=60. For 60 gallons of oil, you would have to have 12 drums because 60÷5=12. Because there is already 8 drums of oil, there would already be 40 gallons because 8x5=40. If the owner already had 40 gallons of oil, they would only have to get 20 more gallons because 60-40=20. That would be 4 drums because 20÷5=4. The owner would have to order 4 more drums of oil.
Using the binomial distribution, it is found that there is a 0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Considering that there are 4 questions, and each has 5 choices, the parameters are given as follows:
n = 4, p = 1/5 = 0.2.
The probability that he answers exactly 1 question correctly in the last 4 questions is P(X = 1), hence:
0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
