The answer would be A. 200 since multiplying 10 shirts times 5 skirts times 4 pairs of shoes will give you 200.
I think you meant...
3^(3x-7)=81^(12-3x) (note that 81=3^4) so
3^(3x-7)=3^4^(12-3x)
3^(3x-7)=3^(48-12x) taking log or natural log of both sides show that
3x-7=48-12x
15x=55
x=11/3
Answer:
2x+4y,9
Step-by-step explanation:
Answer:
APart 1:
A.53 =53
B.3^5/3^-6 =177147
C.(1/4)^3 • (1/4)^2 = 1 /1024
D.(-7)^5/(-7)^7 = 1/49
Step-by-step explanation:
I tried my best for part 2 but i'm pretty sure it's not right. I think 1/1024 and 1/49 has a value between 0 and 1
