12-5(3r+2)=17 I need help on that thats it please

NARA [144]

12 - 5(3r + 2) = 17 |use distributive property a(b + c) = ab + ac

12 - 15r - 10 = 17

2 - 15r = 17 |subtract 2 from both sides

-15r = 15 |divide both sides by (-15)

r = -1

Answer:

Average speed = $\frac{(x+y)}{2}$ miles per hour

Step-by-step explanation:

Formula to calculate the average speed of an object is,

Average speed = $\frac{\text{Total distance covered}}{\text{Time taken to cover this distance}}$

If I travel with the speed of x mph for t hours,

Total distance covered = Speed × Time

= $x\times t$

= $xt$ miles

Similarly, if I travel with the speed y mph for t hours,

Total distance covered = $yt$ miles

Total distance covered by me = $(xt+yt)$ miles

Total time taken to cover this distance = $t+t$

= $2t$ hours

Therefore, expression for the average speed will be,

Average speed = $\frac{xt+yt}{2t}$

= $\frac{(x+y)t}{2t}$

= $\frac{x+y}{2}$ miles per hour
