You a line the decimal points right above each other and add the .45 to .8
<span>Let x be
additional food item the homeroom B should collect to have greater item per student than
homeroom A.</span>
(22 +24 + x) /
16 > (30 + 42 + 21) /24
(22 +24 + x)
> 3.875 (16)
X > 16
<span>So they should
collect more than 16 food item to have a greater item per student</span>
Step-by-step explanation:
Make a point P that will be the vertex of the new angle.
From P, draw a ray PQ. ...
Place the compasses on point A, set to any convenient width.
Draw an arc across both sides of the angle, creating the points J and K as shown.
Hope this helps :)
