Percent means per 100
think cent as in 100 pennies in a dollar
To convert from percent to decimal, we divide by 100 or move the decimal over 2 spots, so,
15% = 15/100 = 0.15
Now multiply 0.15 by 850 to find the discount saved
0.15*850 = 127.50
So you'll save $127.50
The final price is therefore: 850-127.50 = 722.50
A shortcut is to multiply 850 by 0.85
850*0.85 = 722.50
We get the same answer
The 0.85 comes from the fact that if you get 15% off, then you pay 85% of the original price
Answer: $722.50
Answer:
x=-5, y=5 or (-5,5)
Step-by-step explanation:
We can do elimination with this
this means we should first multiply -5x-4y=5 by 2
this would make it -10x-8y=10
we can now subtract this from the original equation
-8x-8y=0 - (-10x-8y=10)
the ys would cancel out
so this would equal
2x=-10
x=-5
now we can plug this back into the equation to find y
-8(-5)-8y=0
40-8y=0
-8y=-40
y=5

Answer:
24.3 ft
Step-by-step explanation:
If h is the height of the ladder up the tree, the geometry can be modeled as a right triangle with legs h and 6, and hypotenuse 25. The Pythagorean theorem gives you the relation ...
h² +6² = 25²
h² = 625 -36 = 589
h = √589 ≈ 24.3
The ladder reaches about 24.3 feet up the tree.
-2(2(5x - 9) -3 (2x + 5))
-2 (10x - 18 - 3 (2x + 5))
-2 (4x -18 -15
Answer = -2(4x - 33)
