I think my answer is a because it can’t be B and it can’t be C and it can’t be D so my answer is a
Answer:
D The solution is 35, which represents the number of miles she runs each week.
Step-by-step explanation:
Given that Gisele trains 7 days a week, the total of miles she cycles and runs in a week can be divided by 7, or multiplied by 1/7 to find her daily average. Her total number of miles ran for the week combined with her cycling miles multiplied by 1/7 would average 20 miles daily. Since the run is the same each day, using the equation:
1/7(105 + r) = 20 will give the value of 'r' in the number of miles ran per week
105 + r = 140 (multiply both sides by '7')
r = 35 (subtract '105' from both sides)

Step-by-step explanation:
|x|=x,if x>0
|x|=-x,if x<0
(a)
|7-9|=|-2|=-(-2)=2
(b)
|7|-9=7-9=-2
