Answer:
The sum of x and y is 8.
Step-by-step explanation:
x+2y=10
x-2y=2
------------
2x = 12, so x = 6. Substituting 6 for x in the 2nd equation, we get:
6 - 2y = 2, or
4 = 2y, or y = 2. The solution is therefore (6, 2).
The sum of x and y is 6 + 2 = 8 (answer)
Price is reduced by 45%. Which means that the new price is 55% of the original.
Therefore, (55/100)*17 = $9.35 =new price
A. 8 pages per hour because 120 (2 hours) ÷15=8
b. $40÷15 (pages)=$2.70 (rounded)
Answer:
B. 246 in^2
Step-by-step explanation:
A = pi r^2 theta /360 if theta is in degrees
A = * pi *(16)^2 * (110/360)
A = *pi* 256 * 11/36
A = 2816/36 *pi
A = 245.74236 in ^2
