Step-by-step explanation:
X=(18.75*100)/75
20 hours because 1 mile is 1 hour so 4 miles is 4 hours so if you times the 5 days by the 4 miles/ hours you get 20 hours in 5 days.
Answer:
5.3
Step-by-step explanation:
8^2 - 6^2 = x^2
64 - 36 = x^2
28 = x^2
Square root of 28 is approx 5.3
When multiplying exponential expressions 7^a and 7^b, you add up the exponents over the same base of 7. This works because the two bases are both 7
So, 7^a*7^b = 7^(a+b) is the answer
Notes:
1) I used the asterisk symbol instead of the 'x' to mean multiply. This is done so we don't confuse the 'x' with a variable.
2) Parenthesis are needed to indicate that all of the "a+b" is the exponent of 7
It is b because idk im just doing this so i can ask more questions
