Answer: x=5
Step-by-step explanation:
i’m not sure if that’s what you meant. there’s not much info.
Distance = 30 mph * time
distance = 4 mph * time
distance = 30 mph * t
distance = 4 mph * (17-t)
Since distance is equal then
30 mph * t = 4 mph * (17-t)
30t = -4t + 68
34t = 68
t = 2 hours
We see the return trip time is (17 -t ) which is 15 hours.
The beginning trip time is 2 hours.
Double Check
Beginning trip = 30 miles * 2 = 60 miles
Return trip = 4 miles * 15 = 60 miles.
Answer:
x=12
Step-by-step explanation:
The two angles shown are complementary angles, so the add to 90 degrees
x+42 + 3x = 90
Combine like terms
4x+42 = 90
Subtract 42 from each side
4x+42-42 = 90-42
4x = 48
Divide by 4
4x/4 = 48/4
x = 12
Answer:
ummm
Step-by-step explanation:
Answer:
You are given such data:
In the 12th grade total of 48 students, only 13 students participate in at least one extracurricular activity and 48 - 13 = 35 students do not participate.
In 11th grade total of 106 - 48 = 58 students, 37 students participate in at least one extracurricular activity and 58 - 37 = 21 students do not participate.
