<span> here
7 7/8
= [ (8*7) + 7 ] / 8
= (56 + 7) / 8
=63 / 8
similarly,
3 1/4
=[ (4*3) + 1] / 4
= (12 + 1) / 4
= 13/4
----------------------------
now put the values
7 7/8 - 3 1/4
= 63/8 - 13/4
here, take LCM of 8 & 4 which is 8.
now,
[ (1*63) - (2 * 13) ] / 8
= (63 - 26) / 8
= 37/8
= 4 5/8........................[ here, divide 37 by 8 which gives reminder as 5 and divisible value as 4 ]</span>
The mode is 4 because it is the number that shows up the most.
Given simplification:
3√7 + 7√63 + (√7/7)
= 3√7 + 7√(9*7) + (√7/7)
= 3√7 + 7*3√7 + (√7/7)
= 3√7 + 21√7 + (√7/7)
= (3+21)√7 + (√7/7)
= 24√7 + (√7/√7)
= (7*24√7 + √7)/7
= (168√7 + √7)/7
= (169√7)/7

Answer:
C
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A hexagon has 6 sides, so n = 6
sum = 180° × (6 - 2) = 180° × 4 = 720° → C
Im probably wrong but i think you would do -4 - 7 + 3 = -8
