Answer:
20%
Step-by-step explanation:
You must divide the difference between the original and new amounts by the original amount.
50-40/50, or 10/50 which is equivalent to 20%
C. 20%
50*2=100
40*2=80
100-80=20
Thanks, so cube root of 512 is 8 and reciprocal of 0.4 is 2.5 then:
8 : 2.5 / divide both by 2.5 to get:
3.2 : 1 that's my answer right?
700-500/500=2
-3x-3x=21-6
9x=15
x=15/9
