Answer:
Volume of composite is 483 
Step-by-step explanation:
We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):
Volume of the prism = 7 x 12 x 3 = 252
Volume of the semi-cylinder = 
Therefore the sum of both volumes gives:
(252 + 230.907) = 482.907
WHich can be rounded to the nearest whole number as: 483
Answer:
First we add 7 on both sides
-7x+3y= -6.3
+7. +7
___________
then we simply
-7x + 7x= -1
bring down the 3y
-6.3+ 7x = 0.23
So, -1x+3y=0.7
2y = 0.7
