A store decreased the price of all its jeans by 20%. If Tara bought a pair of jeans for $50, what was the original price?
Group of answer choices
$40.00
$62.50
$70.00
$60.00
Answer:
the answer is 60 dollars.
====================================================
Work Shown:
x = original price
20% = 20/100 = 0.20
20% of x = 0.20x = discount
x - 0.20x = 0.80x = final price
0.80x = 50
x = 50/0.80
x = 62.50
The original price of the jeans was $62.50
---------------
Note how,
20% of x = 0.20*x = 0.20*62.50 = 12.50
Tara saves $12.50 (this is the discount).
The price she pays is x - 0.20x = 62.50 - 12.50 = 50 dollars, which matches with what your teacher gave in the instructions. This confirms we have the correct original price.

Answer:
what is the question?
Step-by-step explanation:
A software company in Lexington used to bill its clients $170 per hour for work done by its consultants. The company recently adjusted its hourly rate, making it 10% less. What is the new hourly billing rate?
Answer:
$168.3
Step-by-step explanation:
Step one:
Given data
initial billing rate= $170 per hour
the new billing rate is 10% less
Hence the rate reduction is
=10/100*170
=0.01*170
=$1.7
Step two:
Hence the new billing rate is
=170-1.7
=$168.3
5x + 4 = -11 What could you do to further isolate the variable?
5x+4=-11
so subtract 4 from both sides
your left with
5x=-15
Divide 5 from both sides
x=-3

At Leslie's school, the ratio of boys to girls is 11 to 12. At Mark's school, the ratio of boys to girls is 41 to 48. If both schools have the same total
number of students, which statement about the number of boys at Mark's and Leslie's schools is true?
A There are more boys at Mark's school than at Leslie's school because the ratio 11 to 12 is greater than the ratio 41 to 48.
B. There are more boys at Mark's school than at Leslie's school because the ratio 41 to 48 is greater than the ratio 11 to 12.
C. There are more boys at Leslie's school than at Mark's school because the ratio 41 to 48 is greater than the ratio 11 to 12.

5x-3 /4=2x+3
Pls help
Answer:
x=-5
Step-by-step explanation:
5x-3/4=2x+3
First, multiply by 4
5x-3=4(2x+3)
Next, distribute.
5x-3=8x+12
Subtract 5x
-3=3x+12
Subtract 12
-15=3x
x=-5
Hope this helps :D

Not good with factoring could use a hand.
The only factoring you need to do is already done for you:
x² + x - 12 = (x + 4) (x - 3)
What you're asked to do is decompose
(3x - 4) / (x² + x - 12)
into partial fractions, i.e. find a and b such that
(3x - 4) / (x² + x - 12) = a / (x + 4) + b / (x - 3)
Multiply both sides by x² + x - 12 :
3x - 4 = a (x - 3) + b (x + 4)
3x - 4 = (a + b) x + (-3a + 4b)
So we have
a + b = 3
-3a + 4b = -4
and solving this system gives
a = 16/7 and b = 5/7
so you should submit the numbers in bold:
(3x - 4) / (x² + x - 12) = 16 / (7 (x + 4)) + 5 / (7 (x - 3))

Identify the type of slope and then find the slope of the line.
Answer:
-1/2, negative slopeStep-by-step explanation:
As per graph it is visible that the slope is negative, it goes down when x-value increases
Use two points to find the slope:
(-4, -1) and (0, -3)Slope formula:
m = (y2 - y1)/(x2 - x1)Value of the slope:
m = (-3 - (-1))/(0 - (-4)) = -2/4 = -1/2Jus 360 no sniped my little sister get on my Game kid
