B. Warm air rises,and cool air sinks.
8×6= 48
4×6=24, 24+24=48
or
(4×6)+(4×6)=2×4×6=8×6
5/6 + 3/6 = 8/6, you divide 6 into 8, and get 1 2/6, you can reduce that to 1 1/3
Sentence: one and one third
Answer:
y=5 when x=20
Step-by-step explanation:
Using the format for inverse proportions: y=k/x
To find k, substitute 25 in for y and 4 for x to find:
25=k/4 ⇒ k=100
Using this we can substitute k and x in for 100 and 20 to find:
y=100/20 ⇒ y=5
