Answer:

a is positive and b is negative

Step-by-step explanation:

ok, since |a-b| is the absolute value of a-b, so whatever a-b is gonna be it must end up positive

a + b can't both be positive because then a+b not equal to a-b

a cant be negative ever because that would conflict with the absolute value part of the right side of the equation

thus a must be positive and b must be negative

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each p

galina1969 [7]

Answer:

Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478

Step-by-step explanation:

The computation is shown below:

Let us assume the ricky be x

So pedro be x + 276

Now the equation is

x + x + 276 = 2680

2x + 276 = 2680

2x = 2680 - 276

2x = 2404

x = 1,202

For Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478
