If Sheila can ride her bike 6000 meters in 15 minutes, then you can divide
6000 ÷ 15 to find how far she can ride in 1 minute.
6000 ÷ 15 = 400.
So, Sheila can ride her bike 400 meters in 1 minute.
To find how many meters she can ride in 2 minutes, multiply 400 by 2.
400 x 2 = 800.
Sheila can ride her bicycle 800 meters in 2 minutes.
Answer:
The margin of error is multiplied the square root of 2 (I got it right on my test)
Answer:a valid solution is (1,3)
Explanation:First, let' simplify the given equation:
14mn = 55 - 7m - 2n
14mn + 2n = 55 - 7m - 2n + 2n
n (14m + 2) = 55 - 7m
n =
Now, we have only one equation in two unknowns. Therefore, the only way to solve this is by assuming one of the variables and solving for the other taking into consideration that both should be positive integers.
1- Assume m = 2:
n =
.....> n is not a positive integer .........> This assumption is rejected
2- Assume m = 1:
n =
.......> both m and n are positive integers ........> This assumption is accepted ...........> Therefore, the solution would be (1,3)
Hope this helps :)
