According to the rules of indices:
1/a^b=a^-b
thus using this rule, our value will be expressed as follows:
1/z^9=z^-9
Hence the answer is: z^-9
A) constant=40, coefficient=7.50, variable=h
B)7.50h+.20s+40
7.50(25)+.20(300)+40
187.5+60+40=287.5$
C)9.0h+.2s+40, So yes a coefficient would change, but nothing else
Answer:
18
Step-by-step explanation:
1/3 * 18 = 6 or 6/(1/3) = 18 or 6 * 3 =18
