. Which numbers are all divisible by 5? 1. 124, 333, 315, 266, 391 2. 135, 205, 330, 275, 365 3. 135, 211, 330, 274, 252 4. 232,
Ad libitum [116K]
Any numbers are ending with 5 and 0 can divide by 5
so answer:
<span>2. 135, 205, 330, 275, 365</span>
<span>3x + y= 17 (a)
4x + 2 y = 20 (b)
Multiply (a) by 2:
6x + 2y = 34 (a)
4x + 2y = 20 (b)
make: (a) - (b)
2x = 14 -----> x =7
-------------------------------
Replace the value of x = 7 in one of anterior equation:
</span>3x + y= 17
3 x 7 + y = 17
21 + y = 17
y = 17 - 21
y = -4
The two numbers are 19 and 13 because 19+13=32 and 19-13=6
