If you think about how 5 exponentially grows when you make the exponent larger, it gets easier. Since
is 25, and
is 125, then
must equal 625, right? Because 5*5*5*5=625. Hope I made sense!
It represents that she tutored for 0 hours, and earned $0.
Answer:
Step-by-step explanation:
10b +18 <2(4b +2)
10b +18 <8b +4
10 b - 8b <4 - 18
2b <-16
b <-16:2
b <-8
Age of tom=t
age of john=j
age of andy=a
t<a
if j is not older than t, then he is less than or equal to t so
j ≤ t
but there is an oldest so therefor we assume that j < t
t < a
j < t
subsitute
j<t<a
andy is oldest
tom is second
john is youngest
-7/16 - 1/4 - 5/16
1. -7/16 - 4x1/4x4 - 5/16
2. -(7/16 + 4/16 + 5/16)
3. -7 + 4 + 5/16
that will add up to be 16/16 then cancel them out and you get for your answer -1
