Answer:

Step-by-step explanation:

$16.2=2.7(h+1)\\\\2.7\left(h+1\right)=16.2\\\\\mathrm{Multiply\:both\:sides\:by\:}10\\2.7\left(h+1\right)\cdot \:10=16.2\cdot \:10\\\\Refine\\27\left(h+1\right)=162\\\\\mathrm{Divide\:both\:sides\:by\:}27\\\frac{27\left(h+1\right)}{27}=\frac{162}{27}\\\\Simplify\\h+1=6\\\\\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}\\h+1-1=6-1\\\\Simplify\\h=5$

Together, teammates Pedro and Ricky got 2688 base hits last season. Pedro had 284 more hits than Ricky.

Yakvenalex [24]

Answer:

Pedro got 1486 and Ricky got 1202 hits

Step-by-step explanation:

We have that, teammates Pedro and Ricky together got 2688 base hits last season.

This means $p+r=2688$ , where p is the number of hits Pedro got and r number of hits Ricky got.

Also Pedro had 284 more hits than Ricky.

This gives us:

$p=r+284$

We substitute this last equation into the first one to get:

$r+284+r=2688$

2r=2404

Divide by 2 to get:

r=1202

Therefore p=1202+284=1486

Answer: 8

Step-by-step explanation:

Pythagorean theorem - a^2+b^2=c^2

a^2+15^2=17^2

a^2+225=289

(subtract 225 from both sides)

a^2=64

(sq root both sides)

a=8
