Answer:
Step-by-step explanation:
14: k^-3/k^4= 1/k^7
15: answer : 1/3²
16: n^-4
17: f-g^4 = 3-(-5)^4 = -622
18: (x^5-y^2)²+x³ =
(2^5-8^2)²+2³ =1032
19: m²-n³
6²-2³ = 36-8=28
20 : 2²×3²×5³= 4500
4500/10 = 450 islands
7.5
thats the answer i got for this

Step-by-step explanation:
Step-by-step explanation:
Let x be the miles Kenyon ran on tuesday
Let y be the miles Kenyon ran on thursday
Given,
Mon + Tues + Wed + Thu = 8mi

also given,

Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2
Using equation 1,

Substitute this equation into equation 2.

Substitute y = 2.8 into equation 1.

Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.
