Remember:
a^m * a^n=a^(m+n)
a^-m=1/a^m
8³ x 8⁻⁵=8³⁻⁵=8⁻²=1/8²=1/64<1
Answer: the student is not correct, because 1/64<1, and 8³ x 8⁻⁵=1/64.
You would fill in 9 for x so your equation would be 2(9)+3 and you would then get 21. Therefore the answer is f(x)=21
36 = 1/2 (AE - 26)
72 = AE - 26
98 = AE
Answer:
To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate.
Step-by-step explanation:
As an example, in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate.
8/10 is greater than 63/100 because when 8/10 is turned into a percentage it is greater
