1/2 = fraction. 1.2= decimal 12%= percent
You have to make proportions
65mi/1h=125mi/xhours
you end up with 65x=125
125/65=1.92hours--> round it to 2 hours
it takes 2 hours
Answer:
1/2 ; 1/4
Step-by-step explanation:
Number of cards in a deck = 52
Number of red cards = 26
Number of spades = 13
Probability of event A :
P(A) = required outcome / Total possible outcomes
P( red card) = number of red cards / total cards in deck
P(red card) = 26 / 52 = 1/2
P(spade) = number of spades / total cards in deck
P(red card) = 13 / 52 = 1 / 4
Answer:
-2
Step-by-step explanation:
9g-4-5=-27
9g-9=-27
Add 9 to both sides
9g=-18
g=-2
A+7=0
A+7-7=0-7
A=-7
B+3=7
B+3-3=7-3
B=4
