Answer:
<em><u>The equality is true</u></em>
Step-by-step explanation:
<em><u>x+(y+z)=(x+y)+z</u></em>
<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for y</u></em>
<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get</u></em>
<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get-4/15+(-4/5+17/8)=(-4/15+-4/5)+17/8</u></em>
<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get-4/15+(-4/5+17/8)=(-4/15+-4/5)+17/817/24=17/24</u></em>
<em><u>x+(y+z)=(x+y)+zwhen we plug in -4/15 for x,-4/5 for yand 17/8 for z,we get-4/15+(-4/5+17/8)=(-4/15+-4/5)+17/817/24=17/24so this equality is true</u></em>
