Answer:
x=8
Step-by-step explanation:
In this parallelogram, the opposite sides are equal
PN = LM
5x+7 = 9x-25
Subtract 5x from each side
5x-5x+7 = 9x-5x -25
7 = 4x-25
Add 25 to each side
7+25 = 4x-25+25
32 = 4x
Divide each side by 4
32/4 = 4x/4
8 =x
Answer:
C. $70.00
Step-by-step explanation:
First convert the discount rate of 60% into a decimal (0.6)
Remember that the original price(x) times the discount rate(0.6) is the sale price(42).
0.6x=42
divide both sides by 0.6 to get
x=70
The original price was $70.00
2x - 3y = 8....subtract 2x from both sides
-3y = -2x + 8 ...divide both sides by -3
y = 2/3x - 8/3
Answer:
Make the larger pool so that each tree is at the center of each side.
Step-by-step explanation:
For the area to be twice as great, the side lengths need to be multiplied by the square root of the area scale factor: √2. A square oriented 45° from the current square, with the trees at the midpoint of each side, will have side lengths increased by that factor.
Sin(C) is 7/25 because 7 is opposite and 25 is the hypotenuse
Cos (C) is 24/25 because 24 is adjacent and 25 is the hypotenuse
Tan (C) is 7/24 because 7 is opposite and 24 is adjacent
