Answer:
Step-by-step explanation:
<u>We know that:</u>
<u>Solution:</u>
- 3 miles = 45 minutes
- => 1 mile = 45/3 minutes
- => 5 miles = 45/3 x 5
- => 5 miles = 15 x 5
- => 5 miles = 75 minutes
Hence, it takes 75 minutes for Jim to walk 5 miles.
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.
they will fill 23 baskets. we get this by adding the number of golf balls each of them get to get the total number of golf balls. then, we divide the total number of golf balls by 34 because that's how many they will be able to put into each basket. it will look a little like this: 408+374=782
782/34=23 baskets
X^2/(x- 9 = 81/(x - 9)
This is the equation for which you want the solution.
Multiplying both sides of the equation by (x - 9) we get
x^2(x - 9)/(x - 9) = 81(x - 9)/(x - 9)
So the (x - 9) goes out from both the denominator and the numerator and then the simplified equation becomes
x^2 = 81
x ^2 = (9)^2
x = 9
So the value of the unknown variable x comes out to be 9.
