Answer:
Step-by-step explanation:
Since the candy bar is just one
Giving 1/4 of it to her younger sister make her left with 3/4 of the candy bar i.e 1 - 1/4 = 3/4
Then giving 1/3 of the left over to her elder sister it becomes 3/4 * 1/3 =1/4
Then the remaining candy bar will be 3/4 - 1/4 = 1/2
Then she will be left with 1/2 i.e half of the candy bar.
Answer:

Step-by-step explanation:
4 +4+4+4 = 16
Remark
11 and 3 are both prime. So the common denominator is 33

simple multiplication
Answer:
y = - 
x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x + ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= -
Using the point- slope form
with m = - and (x₁, y₁ ) = (- 2, 4) , then
y - 4 = - (x - (- 2) ) , that is
y - 4 = - (x + 2) ← distribute
y - 4 = - x - 3 ( add 4 to both sides )
y = - x + 1 ← in slope- intercept form
