Answer:
3x +5+2x+44+110+123+136=360
5x+418=360
c. l. t
5x=58
therefore X=11.5
Giraffe = 1,000 kg
Whale = 2,000,000 kg
Whale has 2,000 times the mass.
Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
57+57+63
=177
no, there are more students than seats, (unless the players are included in the number?) in that case are there 27 players in a game? idk basketball, on the bench maybe?
