Answer:
Final Cost= 1.09(xx - .05xx)
Step-by-step explanation:
Since its 9% tax on the new price you would take the new price which would be 1.0 and add the .09 of tax. So its ×1.09 to get the tax.
The expression for the total cost is 1.09(xx-(0.05)xx).
What is total cost?The total cost is the amount calculated after any discount for an item and along with the tax incurred for an item to be purchased.
For the given situation,
Ethan buys an item that costs xx dollars.
He has discount coupon of 5% = 0.05
The tax percentage is 9% = 0.09
The discounted amount will get less from the cost price. So,
⇒ [tex]xx-(0.05)xx[/tex]
The tax amount for the item will get added to the final cost of an item. Thus the expression becomes,
⇒ [tex]1.09(xx-(0.05)xx)[/tex]
Hence we can conclude that the expression for the total cost is 1.09(xx-(0.05)xx).

airplane a traveled 1273 miles in four hours.For airplane b y=621 x/2 represents rate of speed over the same four hours wichair plane traveled at a faster rate and by what factor?round to the nearest hundredth
Answer: Airplane A by a scale factor of 1.02
Step-by-step explanation:
Airplane A: 1273/4=318.25
Airplane B: Rate is the slope of equation, 621/2=310.5
So,
318.25/310.5=1.0249
Airplane 'a' is faster than airplane 'b' by a factor of 1.03 times.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An airplane 'a' traveled 1273 miles in four hours.
∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.
For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours
∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.
So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.

3/4 = 1/2y
y=
Answer:
y=1 1/2 (fraction)
or
y=1.5 (decimal)
Step-by-step explanation:
We want to get y alone, so we need to get rid of the 1/2 in front of it. To do that we can multiply each side by 2 since 1/2 + 1/2 = 1.
3/4= 1/2y
multiply each side by 2
To multiply 3/4 by 2 you need to multiply the numerators and then multiply the denominators
2•3=6 & 4 • 1 =4
6/4
simplify
y=1 1/2
(If you need it in decimal form it would be y=1.5)

C. -1/3 · 13 · 12
D. 1/3 · 13 · (-12)
Answer:
Not sure it's either B. or D I put B.
Step-by-step explanation:
The commutativity property is used to get
-12×13×1/3 = -12×1/3×13
What is Commutative property?According to mathematics, an arithmetic operation is commutative if switching the operands' positions has no effect on the computation's outcome.
When two numbers A and B are provided, the commutative property of the numbers formula is as follows:
A+B=B+A
A×B=B×A
A-B≠B-A
A÷B≠B÷A
According to the commutative property formula, the outcome is unaffected by the sequence in which two integers are added or multiplied. However, the order of the integers matters for subtracting and dividing any two real numbers, thus it cannot be altered.
How to solve?The commutativity property is used to get
-12×13×1/3 = -12×1/3×13
such that the evaluation becomes easier, which is to get 12×1/3=4.
The commutativity property is used as follows:
-12×(13×1/3)=-12×(1/3×13)

Solve this equation
2 x + 3 = x - 4
Answer:
-7
Step-by-step explanation:
2x + 3 = x - 4
so you first add four to both sides of the equal sign:
2x + 3 = x - 4
+ 4 + 4
making the equation:
2x + 7 = x
you now subtract 2x from both sides:
2x + 7 = x
-2x - 2x
to get:
7 = -1x
you then divide both sides by -1:
7/-1 = -1x/-1
to get:
-7 equals x or x = -7
