_________
$758.00
So, to do this first we start at the far right and go to the left.
$947.50 - $189.50_________
$ .00
0-0= 0
5-5= 0
You then bring down the decimal.
$947.50 - $189.50_________
$ 8 .00
Because you cannot subtract 9 from 7, you borrow one from the number to the left of it and 7 turns into a 17 as 4 turns into a 3. So then, 17-9=8.
17
$93-7-.50 -7- = This means the 7 has been canceled out and turned - $189.50 into the 17 above _________ 8 .00
This happens again with subtracting 3 from 8 in which you take one from the number beside which happens to be 9 and make it 8.
17
$8-3--7-.50 -7- and -3- = This means the 7 has been canceled out and turned into the 17 above
- $189.50 _________ $ 58 .00
So then, 13-8=5. Finally 8-1= 7
$947.50

If water freezing point is 32 F and water and potassium went down 8 degrees F then it is 24 degrees F is the freezing point for water and potassium
Answer:
40 cm and 42 cm
Step-by-step explanation:
Two leg length: x and x+2
x² + (x+2)² = 58²
2x² + 4x + 4 = 3364
2x² + 4x - 3360 = 0
(x+42) (x-40) = 0
leg length is a positive number so x = 40
another leg = 42
The answer is 80 arc cb has the same measures as the central angle
You determine which one to use by seeing which one would be easier
elimination: 5x + 7y = 2
-5x + 6y = 6
substitution: y = 9x + 5
2y = 7x + 2
