The miles the student biked in two weeks is 11 2/3 miles.
The distance the student bikes is given in fractions. Fractions are numbers that are made up of numerator and denominators. An examples of a fraction is 1/4. 1 is the numerator and 4 is the denominator.
In order to determine the distance biked in 2 weeks, the distance biked in a day has to be determined.
Distance biked in a day = (1/4 + 1/3 + 7/12)
14/12 = 1 2/12 = 1 1/6
Distance he would travel in 2 weeks
1 1/6 x 10
7/6 x 10 = 70 /6 = 11 2/3 miles

Answer:
Yes, it is a solution
Step-by-step explanation:
9x+7y=-11
-2x-5y=30
substitute 5 for x and -8 for y and test:
9(5)+7(-8)=-11
45-56=-11 , this is true
-2(5)-5(-8)=30
-10+40=30 , this is true also
The lines would be parallel to each other and the lines are positive
Answer:
-$1.33 or lose $1.33
Step-by-step explanation:
In this game, there are two possible outcomes.
- There is a 2 in 6 chance (rolling a 5 or a 6) that you win $8.
- There is a 4 in 6 chance (rolling a 1, 2, 3 or a 4) that you win nothing.
Note that for any outcome, you start off paying $4 to play.
The expected value of this game is:

You are expected to lose $1.33 per play.
