Answer:
15 : 175 16: 10 17: 2.5 meters
Step-by-step explanation:
15: 350 - 175 16: 25 - 15 17 since there are 100 centimeters in a meter just count and you will get the answer
Answer:
t=10
Step-by-step explanation:
3*(t+4)-2*(2*t+3)-(-4)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3 • (t + 4)) - 2 • (2t + 3)) - -4 = 0
Step 2 :
Equation at the end of step 2 :
(3 • (t + 4) - 2 • (2t + 3)) - -4 = 0
Step 3 :
Equation at the end of step 3 :
10 - t = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -t+10 = 0
Subtract 10 from both sides of the equation :
-t = -10
Multiply both sides of the equation by (-1) : t = 10

Answer:
There are approximately 1145 vehicles are stuck in the traffic jam. It is very close to option C.
Step-by-step explanation:
To determine:
Estimate how many vehicles are stuck in the traffic jam.
Information Fetching and Solution Steps:
- On a residential single lane road there was a wreck that backed up traffic for 4 miles.
- 70% of the traffic consists of cars and 30% of the traffic consists of trucks.
- The average distance between vehicles is 3 feet.
- The average length of a car is 13.5 feet.
- The average length of a truck is 20 feet.
- There are 5280 feet in 1 mile
Let 'n' be the total number of vehicles stuck in the traffic jam.
So, the equation becomes
