Answer:
x=3, y=1
Step-by-step explanation:
2x+y =7
3x-4y =5
Multiply the first equation by 4 so we can eliminate y
4(2x+y =7)
8x +4y =28
Add this to the second equation
8x +4y =28
3x-4y =5
----------------
11x = 33
Divide by 11
11x/11=33/11
x=3
Now we still need to find y
2x+y=7
2(3)+y =7
6+y=7
Subtract 6 from each side
6-6+y=7-6
y= 1
For number one you have to do 45.6 Divided by 2.54 to get your answer and your answer is going to be 17.95 but The answer actually continues but but sometimes there’s going to be a lot of numbers and people don’t wanna write it down so they’re just gonna cut it short I hope that kind of helped
I don't really understand what you're asking, but say you have the number 67,to find 23% of that number, you would multiply 67 by .23, you will then get whatever 23% of 67 is.
24/16 are both multiples of 8
24/8 = 3 16/8 = 2
3/2
The answer is 34, just plug the numbers in
