Answer:
321
Step-by-step explanation:
2247÷7=321
2 3/5= 10/5 + 3/15= 13/5= 2.6
5 3/5= 25/5 + 3/5= 28/5= 5.6
or
<span>2 3/5+5 3/5= 7 6/5= 8 1/5
I really confuse is one or the other :P</span>
Answer:
no solutions
Step-by-step explanation:
4x + 2y = –14
6x + 3y = –22
Divide the first equation by 2 and the second equation by 3
4x/2 + 2y/2 = –14/2 2x +y = -7
6x/3 + 3y/3 = –22/3 2x + y = -22/3
The left hand sides are the same but the right hand sides are different.
Multiply the second equation by -1
2x+y = -7
-2x -y = 22/3
-------------------
0 = -7+22/3
0 = 1/3
This is never true, so there are no solutions
Answer:
13/6
Step-by-step explanation:
6/13 * x = 1
Multiply each side by 13/6
6/13 * 1/3 6 * x = 1 * 13/6
x = 13/6
