In the given question, it is given that
Isaac take 5 minutes to ride his bike to down the hill to school and 10 minutes to ride up the hill from school. He attends school Monday through Friday.
So per day, from Monday to Friday, Issac rides 15 minutes.
And in 2 weeks, Issac have to ride 10 days.
So in 10 days, Issac rides,
Answer:
C. 4 weeks
Step-by-step explanation:
Trish and Aria are walking to raise money for the school library. Trish has walked 38 miles and walks 10 miles each week. Aria has walked 30 miles and walks 12 miles each week
After how many weeks will Trish and Aria have walked the same number of miles? A. 2 weeks B. 3 weeks C. 4 weeks D. 5 weeks
Trish = 38 + 10x
Aria = 30 + 12x
Where,
x = number of weeks
After how many weeks will Trish and Aria have walked the same number of miles?
Equate both equations
38 + 10x = 30 + 12x
38 - 30 = 12x - 10x
8 = 2x
x = 8/2
x = 4 weeks
Answer:
Step-by-step explanation:
9X+5Y=35
2X+5Y=0
-(2X+5Y=0)
-2X-5Y=0
9X+5Y=35
7X=35
X=5
2(5)+5Y=0
10+5Y=0
5Y=-10
Y=-2
X=5 Y=-2
Answer: A
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+3)+25=3x-17 [combine like terms]
2x+28=3x-17 [subtract both sides by 2x]
28=x-17 [add both sides by 17]
x=45
Now, we know that the answer is A.
