Answer:
8x−14
Step-by-step explanation:
3x - 4 + 5x - 10
=3x+−4+5x+−10
Combine Like Terms:
=3x+−4+5x+−10
=(3x+5x)+(−4+−10)
136.8 meter, or 137 meters
Work:
60 minutes x 24 hours =
1,440 minutes in a day
1,440 minutes x 9.5 cm =
13,680 centimeters
13,680 cm = 136.8 meters // 137
The angle sum in a triangle is 180
30 + 45 = 75
180 - 75 = 105.
The remaining angle measure is 105°.
Answer:
You taught for 4 hours
Step-by-step explanation:
Let this number of hours be x. Then:
Total earned = $20 + ($8/hr)x
Equate this to $52 and then solve the resulting equation for x:
20 + 8x = 52
Then 8x = 32, and x = 4. You taught for 4 hours.
