Answer:
$8
Step-by-step explanation:
for a discount of 20% we require to calculate 20% of $40
20% = 
= 0.2, hence
discount = 0.2 × $40 = $8
If you paid $22.26 after the discount and tax then 30% is 0.30 and 30% OFF is 1-0.30=0.70
Tax is 6% or 0.06 and along with the initial is 1+0.06=1.06 so P is original price in P×0.70×1.06=22.26
P×0.742=22.26
P=$30 was the original price
Answer:
x=6
Step-by-step explanation:
Given the x-intercepts of a parabola: 
The equation of symmetry at the parabola's vertex is x=h
Where 
In this case,
Therefore, the line of symmetry of the parabola is x=6 and is also the x-coordinate of the parabola's vertex.
Answer:
x = 12
Step-by-step explanation:
The two marked angles where the transversal crosses the parallel lines are alternate interior angles, so are congruent. This fact gives you the relation you need to solve for x.
4x +12 = 60
4x = 48 . . . . . . subtract 12
x = 12 . . . . . divide by 4
Answer:
Multiplication (150x4=600 25x4=100%)
