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

F(x)=-5x-7 g(x)=6x-4<br><br> Find F(x)+g(x)<br><br> Please show steps
olga_2 [115]

Answer:

hi!

So it gives you what f(x) equals AND what g(x) equals.

So, if you want F(x)+g(x), then just fill it in!

So it would be

-5x - 7 +6x - 4

-5x+5x-7+6x+5x-4

-7+11x-4

-7 + 7 +11x - 4+7

So, your answer would be 11x + 3

Hope i helped!
