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

Respuesta :

Answer:

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)

The values of p and r are 1471 and 1195, respectively

The system of equations is given as:

p+r= 2,666

p=r + 276

Substitute r + 276 for p in the first equation

r + 276+r= 2,666

Collect like terms

r +r= 2,666- 276

Evaluate the like terms

2r= 2390

Divide both sides by 2

r= 1195

Recall that:

p = r + 276

So, we have:

p= 1195 + 276

p= 1471

Hence, the values of p and r are 1471 and 1195, respectively
