In this question, you're solving the inequality for x.
Solve:
-1/3(6x - 15) + 6x > 8x - 11
Distribute the -1/3 to the variables in the parenthesis.
-2x + 5 + 6x > 8x - 11
Combine like terms
4x + 5 > 8x - 11
Subtract 8x from both sides
-4x + 5 > - 11
Subtract 5 from both sides
-4x > -16
Divide both sides by -4, while also flipping the inequality, since you're dividing by a negative.
x < 4

Answer:
B will be the answer...
Step-by-step explanation:
The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.
To do that, we need to multiply the first equation by 5.
5 (-x − 2y = 7)
-5x − 10y = 35
Add to the second equation. Notice the x terms cancel out.
(-5x − 10y) + (5x − 6y) = 35 + (-3)
-16y = 32
Combining this new equation with the first equation from system A will get us system B.
-x − 2y = 7
-16y = 32
Answer:
answer = 12 min
Step-by-step explanation:
40% of 30 min = ?
10% of 30 min = 3
3*4 = 12
Thus, she spends 12 min of her 30 min lunch driving

Answer:
Step-by-step explanation:
given that certain tubes manufactured by a company have a mean lifetime of 800 hours and a standard deviation of 60 hours.
Sample size n =16
Std error of sample mean = 
x bar follows N(800, 15)
the probability that a random sample of 16 tubes taken from the group will have a mean lifetime
(a) between 790 and 810 hours,
=
(b) less than 785 hours

, (c) more than 820 hours,

(d) between 770 and 830 hours
