Number of gallons of gAS USED / WEEK = 150/25 = 6 gallons
Cost = 6 * 3 = 18 dollars (answer).
Answer: x=26
Step-by-step explanation:
1. Write the equation 2x-5+4x-1+30=180 because all triangle angles add up to 180°
2. Simplify the equation by combining like terms. Write the equation as 6x+24=180
3. Subtract 24 from both sides. Write the equation as 6x=156.
4. Divide 156/6 and get 26. That is your answer (x=26).

Answer:
So on this case the 95% confidence interval would be given by (155.301;159.299)
And the best option would be:
B. (155.3, 159,3)
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n=234 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The Confidence level is is 0.95 or 95%, the significance is 
and 
, the critical value for this case would be 
And replacing we got:
So on this case the 95% confidence interval would be given by (155.301;159.299)
And the best option would be:
B. (155.3, 159,3)
Answer x < -6.
So to solve for x, get it down to its lowest terms we have to isolate x.
We first want to do that by getting rid of the dividing 3 over x. We can do that by multiplying 1/3 by 3, it’s reciprocal…and what we do to one side we have to do to another. So we will also multiply the -2 on the other side by 3. (Which is -6) This will cancel it out and leave us with our final answer…
x < -6
