Answer:

30 cars

Step-by-step explanation: 3 cars per 30 sec , their is 60 sec in a min

30x2=60

5x6=30

You multiply by 6 because you need to figure out how many cars pass in 1 min which is 6

Hopefully this makes sense.

the length of a rectangle is two feet greater then twice its width if the primeter is 25 find the width
Mademuasel [1]

Answer:

Step-by-step explanation:

Perimeter is simply length + width. They gave us that the length is 2 feet plus 2 times the width:

25=(2w+2)+W

Subtract 2 from both sides to get 23 = 2w + w

Combine like terms to get 23 = 3w

Divide by 3 to get w=7 \frac{2}3} feet
