Answer: 11 and -13
Step-by-step explanation:
first you need to isolate one variable so you can later plug it into the other equation
x+y = -2
y = -x - 2
now, you plug this y value into the next equation for the difference that equals 24 and solve for x
x-y = 24
x - (-x-2) = 24
2x + 2 = 24
2x = 22
x = 11
now that you have x, you can just plug it back into either original equation to get the corresponding y equation.
11 + y = -2
y = -13
proof:
11 - (-13) = 24
11 + (-13) = -2
Answer:
Light Red
Step-by-step explanation:
The pH of apple juice is found to be in the range of 2.9 - 3.5. So, the Colour of the universal indicator (pH paper) will be light red.

Just think 200% = 2x, so 2x of 18 = 36. Now for the 20%. Thats one fifth, so just do 18/5 and you have your answer when you add those together
