Question

P is 4 more than 3 times r.the sum of p and r is 10. which of the following are true about p and r

Answer 1

Step-by-step explanation:

Given, p is 4 more than three times r.

$p = 4 + 3r$

Also,

$p + r = 10$

By solving both equations, we get

$4 + 4r = 10 \\ 4r = 6 \\ r = \frac{6}{4} \\ r = \frac{3}{2}$

Since r=(3/2), we can find p by

$p + r = 10 \\ p + \frac{3}{2} = 10 \\ p = 10 - \frac{3}{2} \\ p = \frac{17}{2}$

Hence, p=17/2 and q=3/2.

Choose the correct option with this data.
