Answer:
5 and 6
Step-by-step explanation:
let the 2 consecutive integers be n and n + 1 , then
3(n + 1) = 5n - 7
3n + 3 = 5n - 7 ( subtract 3n from both sides )
3 = 2n - 7 ( add 7 to both sides )
10 = 2n ( divide both sides by 2 )
5 = n and n + 1 = 5 + 1 = 6
the 2 consecutive integers are 5 and 6
Standard form is ax+by=c
Steps:
y + 4 = 1.5(x - 4)
y + 4 = 1.5x - 6
-1.5x + y = -10 is the standard form.
Answer:
Yes

4 x 4 =16
____ _____
15 x 4 = 60
Answer:
60 mph
Step-by-step explanation:
Their average speed while driving is ...
speed = distance / time
= (270 mi)/((3 + 1.5) h) = 60 mi/h
The Johnson family averaged 60 mph <em>while driving</em>.
__
Their average speed for the trip is unknown, because we don't know how long the lunch stop was.
