X = tuna, y = BLT
x + y = 30
6x + 9y = 240
3y = 60
y = 20
x = 10
20 BLTs for $2.50, 10 tuna for $1.50
Answer:
26 units
Step-by-step explanation:

Using the formula above,
distance between (-10, 3) and (0, 27)




= 26 units
Write an inequality to describe the region is x < 0 < 3
Inequalities in three dimensions:
When an inequality representing a region in three dimensions contains only one of the three variables, then the other two variables have no restrictions. We use inequalities to describe solid regions in three dimensions.
Answers and Explanation:
The y z - plane is represented by the equation x = 0
As the region is between this plane and the vertical plane x = 3, we will get the inequality 0 < 0 < 3
Thus, the desired inequality is
0 < 0 < 3.

I'm assuming you meant this. (6*7) - (3^2) *(9+4^3)
(42) - (3^2) * (9+4^3)
(42) - (9) * (9+4^3)
(42) - (9) * (9+64)
(42) - (9) * (73)
42 - 657
