Answer:
Option 400p/500-p
Step-by-step explanation:
Let the number of newspaper A sold be 'x'
and the number of newspaper A sold be 'y'
Therefore,
Total revenue = $1x + $1.25y
Total newspapers sold = x + y
Therefore,
according to the question
r =
..........(1)
and,
p = 
or
(x + y)p = 100x
or
y = 
or
y = 
substituting y in 1
r =
or
r = 
or
r = 
multiply and divide the RHS with 4
we get
r = (400p)÷(500-p)
hence,
Option 400p/500-p
Answer:
y = ±
Step-by-step explanation:
step 1: substitute 'x' for 'y'
x = y² + 3
y² = x - 3
last step: solve for 'y'
y = ±

Answer:
50%
Step-by-step explanation:
For x, y, and z to form a triangle, the sum of the shorter sides must be greater than the longest side.
The total number of combinations is:
2 × 3 × 2 = 12
Write out each combination, and check if they can form a triangle.
3, 4, 5: yes
3, 4, 13: no
3, 5, 5: yes
3, 5, 13: no
3, 12, 5: no
3, 12, 13: yes
5, 4, 5: yes
5, 4, 13: no
5, 5, 5: yes
5, 5, 13: no
5, 12, 5: no
5, 12, 13: yes
Of the 12 combinations, 6 can form triangles. So the probability is 6/12 or 50%.
