That equal 1 because they are the same
15.69 because 49.57-2.50 divided by 3 =15.69
It’s the 2nd answer to the right
Basically, you'd do:
0.2 * 52 (0.2 = 20%, 21% = 0.21)
Your Answer:
10.4
Hello!
-2x + y = 1
-4x + y = -1
You can subtract these equations from each other to eliminate y
2x = 2
Divide both sides by 2
x = 1
Put this into one of the original equations
-2(1) + y = 1
Combine like terms
-2 + y = 1
Add 2 to both sides
y = 3
The answer is D) (1, 3)
Hope this helps!
