Julie wants to buy cartons of apple juice with $55. Each carton costs $3.75.
Let x be the number of cartons she can buy.
3.75x =< 55
Divide both sides by 3.75
3.75x / 3.75 =< 55/3.75
x =< 14.66666
Of course, she can't buy 14.666 cartons so we can the integer part only. Julie can buy 14 cartons of Juice.
Hope this helps! :D
The expression is
5x + 5y
We are to prove that it is an odd integer when x and y are integers of opposite parity
First, we can assume
x = 2a (even)
y = 2b + 1(odd)
subsituting
10(a + b) + 5
5 [(2(a + b) + 1]
The term
2(a + b) + 1 is odd and the result of an odd number multiplied by an odd number is odd

Answer:
2π feet
Step-by-step explanation:
9:30 PM to 1:30 AM is 4 hours.
It is 1/3 of a complete revolution.
A full 12 hours would be 2×r×π=2×3×π
1/3 of that is:
1/3×2×3×π=2π
≈6.283185307 feet
