Answer:
Step-by-step explanation:
(t+s)(x) = t(x) + s(x) = 5x - 6
(t-s)(x) = t(x) - s(x) = -3x - 6
(t * s) (-2) = t(-2) * s(-2) = 48

Answer:
.4 hours or 24 minutes
Step-by-step explanation:
We can use proprtions to solve this problem. Put distance over time
65 miles 26 miles
------------- = -----------
1 hour x hours
Using cross products
65x = 26
Divide by 65
65x/65 = 26/65
x = .4 hours
or we can change to minutes
.4 hours * 60 minutes/ 1 hour = 24 minutes
Answer:
31/40
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 270, number of total outcomes = 1200
Probability (the number of people from the suburbs attending the concert is 270) = 270/1200 = 9/40
Probability (the number of people from the suburbs attending the concert is fewer than 270) means that the number of people from the suburbs attending the concert is not 270 = 1 - 9/40 = (40-9)/9 = 31/40
Answer:
an answer is precise when it is an exact number like 10, 2, or 123.
An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11
