Answer:
It would take the smaller pipe 28 minutes to fill up the truck.
Step-by-step explanation:
Since the larger pipe takes 84 minutes and is three times faster than the smaller pipe, you have to divide 84 by 3 to get 28. To check if this is correct you have to multiply 28 by 3 and you get 84. Showing that the larger pipe is three times faster.
For this case we must find the solution set of the given inequalities:
Inequality 1:

Applying distributive property on the left side of inequality:

Subtracting 3 from both sides of the inequality:

Dividing by 6 on both sides of the inequality:

Thus, the solution is given by all the values of "x" greater than 3.
Inequality 2:

Subtracting 3x from both sides of the inequality:

Subtracting 3 from both sides of the inequality:

Thus, the solution is given by all values of x less than 4.
The solution set is given by the union of the two solutions, that is, all real numbers.
Answer:
All real numbers
Answer:
6
Step-by-step explanation:
to find the perimeter of a trapezoid you add all the sides together
therefore we do it backwards
24-3-6-9=6
Answer:
1. y = 2/3 x +2
2. y = -x -8
Step-by-step explanation:
The slope intercept form of a line is y = mx+b where m is the slope and b is the y intercept
1. y = 2/3 x +2
2. y = -x -8
Add -2 on the both sides
x+2-2=9-2
x=7
