3/12 divided by 1 gets you 1/4 because they are equivalent fractions
Answer:
Hallie ride 62 miles on bicycle.
Step-by-step explanation:
Given:
Let the number of miles Samantha rode be 'x'.
Hallie rode her bicycle 7 miles less than 3 times the number of miles Samantha rode.
It means that number of miles Hallie ride is equal to 3 multiplied by number of miles Samantha rode and then subtracting by 7.
framing in equation form we get;
number of miles Hallie ride = ![3x-7](https://tex.z-dn.net/?f=3x-7)
But Given:
number of miles Samantha rode =23 miles.
Now by substituting the value of
in above equation we get;
number of miles Hallie ride = ![3x-7 = 3\times23-7 = 69-7 = 62 \ miles](https://tex.z-dn.net/?f=3x-7%20%3D%203%5Ctimes23-7%20%3D%2069-7%20%3D%2062%20%5C%20miles)
Hence Hallie ride 62 miles on bicycle.

Answer:
supplement of 158 degree
x+158=180
x=180-158
x=22 degree.
Step-by-step explanation:
Answer:
(x - 1) (x - 2) (x + 2) (x + 3)
Step-by-step explanation:
Factor the following:
x^4 + 2 x^3 - 7 x^2 - 8 x + 12
The possible rational roots of x^4 + 2 x^3 - 7 x^2 - 8 x + 12 are x = ± 1, x = ± 2, x = ± 3, x = ± 4, x = ± 6, x = ± 12. Of these, x = 1, x = 2, x = -2 and x = -3 are roots. This gives x - 1, x - 2, x + 2 and x + 3 as all factors:
Answer: (x - 1) (x - 2) (x + 2) (x + 3)
