If the original price is x, then x-0.10x=0.9x (which is a 10 percent off discount - 10 percent = 0.10 if you move the decimal spot 2 places over), then 10% of 0.9x is not 0.10x due to that 0.1/0.9=1/9, not 1/10. 1/10 of 0.9 is 0.09, so
0.9-0.09=0.81 of the original price
If the 10% sales tax was added first, it wouldn't matter since you're still getting 10% twice either way
Answer:
the answer is 216 square feet because if you multiply 8 ×3=24 and 24×9=216.
A is at (2,-2). after 90 degree counter clockwise, it is at (2,2). Then, a transformation one unit to the left gets it to A', (1,2)
A)
X=4
Step 1: Simplify both sides of the equation.
1.5(x+4)-3=4.5(x-2)
(1.5)(x)+(1.5)(4)+ -3 =(4.5)(x)+(4.5)(-2)
(1.5x) + ( 6+-3) =4.5x - 9
(Combine like terms)
1.5x+3=4.5x-9
Step 2: Subtract 4.5x from both sides.
1.5x +3 -4.5x =4.5x=-9-4.5x-3x+3=-9
Step 3: Subtract 3 from both sides.
-3x+3-3=-9-3
-3x=12
Step 4: Divide both by -3
-3x/-3=-12/-3
X=4
Answer:
1/36
Step-by-step explanation:
A die can roll a 1,2,3,4,5,6
P (5) = number of 5's / total
= 1/6
The 2nd roll is independent so the probability is the same
P (5) = number of 5's / total
= 1/6
P(5, 5) = 1/6*1/6 = 1/36
