ark found a shirt on sale for 25% off. When he brought it to the register, he discovered that all items in the store were on sale for an additional 20% off. He wrote this expression to represent the final cost of the shirt based on the original price, p. (1−0.2)(1−0.25)p When Mark simplifies this expression, what can he conclude about the sale price of the shirt?

QP/TS= QR/TU
6/TS= 9/19
cross multiply
(6*19)= (9*TS)
114= 9TS
divide both sides by 9
12.666666= TS
round up to the tenths decimal place
12.7= TS
ANSWER: D) 12.7 is TS
Hope this helps! :)
QR=9
QP=6
TU=19
TS=?
Okay so the triangles are kindred, now the equation can be made
9/16=6/x
So now we are going to cross multiply
9x=114
Now divide both sides by
912 2/3
Your answer is:
TS=12.6 the correct answer is D.12.7

Answer:
The quotient of the division is given by:
(125 - 8x^3) / (25 + 10x + 4x^2) = - ((2x - 5) * (4x^2 + 10x + 25)) / (4x^2 + 10x + 25) = - (2x - 5) = - 2x + 5
The correct result would be - 2x + 5.

There are two kinds of solving but elimination seems best for this system:
-2x-9y=-25
4x+9y=23 (multiplied it by -1 so you can eliminate the variable "Y")
---------------
2x=-2
x=-1 (divide by 2 on each side)
-2(-1)-9y=-25 (insert what you received for what "X" is)
2-9y=-25 (simplify)
-9y=-27 (subtract 2 on each side)
y=3 (divide each side by -9)
(-2/9)x+25/9 and (-4/9)x+23/9.
Then equate them to each other
(-2/9)x+25/9=(-4/9)x+23/9
Then solve of x
(-2/9)x+(4/9)x = (23/9) - (25/9)
X = -1
Then plug in X and solve for y
Y = (-2/9)(-1) + (25/9)
Y= (27/9)
Y= 3
So your solution is (-1,3)
