Answer:
600
Step-by-step explanation:
To find 100% we can divide by 30 (to find 1%) then times by 100 (to find 100%)
90÷30=3
3×100=300
100%=300
200%=300×2
200%=600
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
