Answer: the number of miles that Bryan hiked is 160
Step-by-step explanation:
Total distance that Bryan hiked last summer was 8.48x 10^5 feet.
There are approximately 5.3 x 10^3 feet in a mile. Converting 8.48 × 10^5 feet to miles, it becomes
8.48 × 10^5/5.3 x 10^3
Applying the rules of indices which is expressed as
a^x ÷ a^y = a^(x - y)
It becomes
= 1.6 × 10^ (5 - 3)
= 1.6 × 10^2
= 160 miles
Answer:
x = -2
Step-by-step explanation:
The given equation is a multi-step equation since it has the variable on both sides of the equal sign. However, the goal of any equation is to isolate the variable (get it by itself) by using inverse (opposite) operations to get the variable on one side of the equal sign and the numbers on the other.
5x - 5 = 3x - 9
1. Subtract '3x' from both sides:
5x - 3x - 5 = 3x - 3x - 9
2x - 5 = -9
2. Add '5' to both sides:
2x - 5 + 5 = -9 + 5
2x = -4
3. Divide '2' from both sides:
2x/2 = -4/2
x = -2
Answer:
1
Step-by-step explanation:
All the numbers provided can have a factor of 1.
eg.)
1*24=24
1*14=14
1*21=21
This is because there is only one factor they all commonly share, 1.
