7. Pedro has 276 more hits than Ricky. Use

substitution to solve the system of equations

to find how many hits Pedro, p, and Ricky,

r, have each recorded.

p+r = 2,666

p=r + 276

Pedro hits 1471 times and Ricky hits 1195 times.

Step-by-step explanation:

Pedro has 276 more hits than Ricky.

So, p = r + 276 ... (1)

And their total hits is equal to 2666.

p + r = 2666 ... (2)

Now, substituting the value of p from equation (1) to equation (2) we get,

r + 276 + r = 2666

⇒ 2r = 2390

⇒ r = 1195

Hence, from equation (1) we get p = r + 276 = 1471.

Therefore, Pedro hits 1471 times and Ricky hits 1195 times. (Answer)
