Step-by-step explanation:
The shortest distance d, of a point (a, b, c) from a plane mx + ny + tz = r is given by:
--------------------(i)
From the question,
the point is (5, 0, -6)
the plane is x + y + z = 6
Therefore,
a = 5
b = 0
c = -6
m = 1
n = 1
t = 1
r = 6
Substitute these values into equation (i) as follows;
Therefore, the shortest distance from the point to the plane is
Answer:
The equation to describe the situation is
And, the total weight of the basket of apples was <u>20 pounds</u>.
Step-by-step explanation:
<u><em>The question is incomplete so, the complete question is below:</em></u>
Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?
Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.
So, the basket of apples total weighed =
Liang ate apples weighed = 3 pounds.
And the apples left for the pies weighed = 17 pounds.
Now, to write an equation describing the situation:
<u><em>Thus, the equation is </em></u><u><em /></u>
Now, to get the total weight of the basket of apples:
<u><em>Hence, the basket of apples total weighed = 20 pounds.</em></u>
Therefore, the equation to describe the situation is
And, the total weight of the basket of apples was 20 pounds.
