on another training ride, Jana bikes 15 miles in 50 mins. Explain how you could find the number of miles she bikes in 1 hour

18 miles

Step-by-step explanation:

Okay first I divided 15 and 50 by 5 this gives me miles for every 10 minutes this gave me 3 miles for every 10 minutes. Then I multiplied this by 6 because there are 60 minutes in an hour and got 18

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
