15 + 35 = 50
To calculate the percentage change from 50 to 35, you first find the difference: 50 - 35 = 15. Then, divide the difference by the original value (50) and multiply by 100: (15 / 50) * 100 = 30%. Since the value decreased from 50 to 35, it represents a 30% decrease.
The sum of -15 and -35 is -50.
That depends what the value of a is.

122 is the answer, NOT 142(as the previous poster said, which is wrong.) This is why: 35+47=82 82-10=72 72-50=22 22+100=122
Multiplication is done before addition, so it will be done before the plus. The result is:35 + 3 x 5 = 50
