x+2 (x+2) + 8

------- = ---------------

14 14+9

solve by using cross products

(x+2) * (14+9) = 14*(x+2+8)

(x+2)*23 = 14*(x+10)

distribute

23x+46 = 14x+140

subtract 14x from each side

9x+46 = 140

subtract 46 from each side

9x =94

x = 94/4

x = 10 4/9 cm

Together, teammates Pedro and Ricky got 2673 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each

ioda

Answer:

Pedro got 1520 base hits and Ricky got 1243.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of base hits that Pedro got.

y is the number of base hits that Ricky got.

Pedro and Ricky got 2673 base hits last season.

This means that $x + y = 2763$

Pedro had 277 more hits than Ricky.

This means that $x = y + 277$

Replacing in the first equation

$x + y = 2763$

$y + 277 + y = 2763$

$2y = 2486$

$y = \frac{2486}{2}$

$y = 1243$

$x = y + 277 = 1243 + 277 = 1520$

Pedro got 1520 base hits and Ricky got 1243.

Can someone help me? I'm lost.

KengaRu [80]

First step is to find R
use The equation QR =43

R=43/Q
now since we have R plug that into PR= 9x - 31

P(43\Q) = 9x - 31
P43/QP +31 =9x
9x=P43÷QP +31
x=P43÷QP+31 /9

Since the question doesnt specify to leave the question in terms of P or Q i suppose this is the final answer

Hope this helps! xD
would not mind if you put it as the brainliest answer
