Answer:
26
Step-by-step explanation:
Plug in 15 for y in the first problem so instead of y=x-11 it would be 15=x-11
15=x-11
+11= +11 (you want to add 11 to both sides to get x by its self)
26=x
Answer:
10/5
Step-by-step explanation:
Because 10 is half of 5 and they are asking what will make this statement true 1/2 is half too
Answer:

Step-by-step explanation:
Let the equation of the line be
where, 'm' is its slope and
is a point on it.
Given:
The equation of a known line is:

A point on the unknown line is:

Both the lines are perpendicular to each other.
Now, the slope of the known line is given by the coefficient of 'x'. Therefore, the slope of the known line is 
When two lines are perpendicular, the product of their slopes is equal to -1.
Therefore,

Therefore, the equation of the unknown line is determined by plugging in all the given values. This gives,

The equation of a line perpendicular to the given line and passing through (4, -6) is
.
solution:
= $15 for 3 packages
= 5 packages per dollar (15/3)
