Answer:
m = 1/4
Step-by-step explanation:
slope = rise / run
rise = 1 (red arrow)
run = 4 (dotted line)
First one simplifies to 2x + 6 = 2x + 7 which can't be true so this one has No Solution.
Same applies to the second equation ( 5x + 15 = 5x - 15) No solution
also the last one has no solution because it simplifies to 4x + 20 = 4x + 19
The sale price S (in dollars) of an item is given by the formula
S=L−rL , where L is the list price (in dollars) and r is the discount rate.
Since, S = L -rL
rL = L -S
r = 
r = 
Since, the listed price of the shirt is $30, we have to find the discount rate.
Therefore, r =
is the discount rate.
Answer:
3/10 or 0.3 or 30%
Step-by-step explanation:
Its 225/750 total students
We simplify this by dividing by 5
45/150
Divide by 5 again
9/30
Divide by 3
3/10
