Six times Jason's collection of books and one-third of Nathan's collection add up to 134 books. One-third of Jason's collection

siniylev [52]

6j+ $\frac{1}{3}$ n=134

$\frac{1}{3} j+n=31$ you multiply this by 18

6j+18n=558
6j+1/3*n=134
___________(-)

53n/3=424 => 53n=1272 => n=24

You put n in the first equation:
6j+8=134
6j=126 => j=21

Final answer: Nathan has 24 books and Jason 21.

If WX= 82 cm, find the length of YZ. (OV = 9cm and OV is perpendicular to YZ)

damaskus [11]

The length of the measure of YZ is 80cm

<h3>Perpendicular lines</h3>

Perpendicular lines are lines that are at angle 90 degrees to each other. From the given diagram;

WX = 82cm

Required

Length. of YZ

Using the pythagoras theorem

YV = VZ = √41²-9²

YV = VZ = √1600

YV = VZ = 40

Since YZ = YV + VZ

YZ = 40cm + 40cm

YZ= 80cm

Hence the length of the measure of YZ is 80cm
