Answer:
3/2
Step-by-step explanation:
formula k = y/x
comes from
y = kx
k = constant of variation
when y = 3 , x = 2
k = 3/2
Answer:
2.69≤x≤17.31
Step-by-step explanation:
Lety the amount in the other Piggy bank be x.
The difference in the amount of money between the two banks is no more than $10 is expressed as;
|x-7.31| ≤ 10
The value in the modulus sign can be positive or negative
If positive;
x-7.31 ≤ 10
x ≤ 10+7.31
x≤17.31
If negative
-(x-7.31) ≤ 10
-x+7.31 ≤ 10
-x ≤ 10-7.31
-x ≤ 2.69
Multiply both sides by -1
x ≥ -2.69
The compound inequality representing the amount of money in the other bank is -2.69≤x≤17.31
Answer:
6 and 7
Step-by-step explanation:
x + y = 13
xy = 42
I just listed the two equations out and the answer just popped out. The trick to this is just thinking about two numbers that obviously both below 13 that add up to it. 6 and 7 is the solution.
Answer:
150
Step-by-step explanation:
15 times 8 = 120
14-8 = 6
6 times 5 = 30
150
Answer:
At 10:30 A.M.
Step-by-step explanation:
A college offers shuttle service from Dickson Hall or Lot B to its campus quad.
At 9:10 A.M the first shuttle leaves from their locations for the campus.
If the shuttles leave from Lot B every 10 minutes and leave from Dickson Hall every 12 minutes, then both the shuttles will leave their origin at the same time after 60 minutes.
This is because 60 is the smallest multiple of 10 and 12 which is common for them.
Therefore, 10:30 A.M. is the next time when both shuttles will depart for the campus at the same time. (Answer)
