multiply top eqatyion by -1 and add to 2nd
9x-2y=24
<u>-x+2y=8 +</u>
8x+0y=32
8x=32
divid both sides b y8
x=4
sub back
-x+2y=8
-4+2y=8
add 4 to both sides
2y=12
divide both sides by 2
y=6
(x,y)
(4,6)

1 hour = 60 min = 360 degree
1 min = 360/60 degree
1 min = 6 degree
and the gap of hour hand and minute hand at 1pm, is of 5 min
therefore acute angle formed is 5 X 6 = 30 degrees.

Answer:
Step-by-step explanation:
area of triangular endface = ½×6×8 = 24 cm²
area of rectangular endface = 4×8 = 32 cm²
area of each endface = 24+32 = 56 cm²
area of each 3×10 face = 30 cm²
area of 3×4 face = 12 cm²
area of base = 8×3 = 24 cm²
surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²
