the sum of the speeds of two trains is 721.6 miles per hour. if the speed of the first train is 8.4 mph faster than that of the
olya-2409 [2.1K]

Subtract the faster speed:

721.6 - 8.4 = 713.2

Divide by 2 trains:

713.2/2 = 356.6

The slower train is going 356.6 miles per hour.

The faster train is going 356.6 + 8.4 = 365 miles per hour.

-5 = 1 / 3 ( -1 - w )<br> plz help with step by step answer
sweet [91]

Step-by-step explanation:

- 5 =  \frac{1}{3} ( - 1 - w) \\  \frac{1}{3} ( - 1 - w) =  - 5 \\   - 1 - w =  - 5 \div    \frac{1}{3}  \\  - 1 - w =  - 5 \times 3 \\  - 1 - w =  - 15 \\  - w =  - 15 + 1 \\   - w =  - 14 \\ w = 14

To form 3 adjacent squares (as in the figure), 10 toothpicks are required. How many toothpicks are required to form 100 adjacent
Sonja [21]
<span>Let's say in general you want "n" adjacent squares. Each one needs a top, so that's n toothpicks. Each one needs a bottom, so that's another n toothpicks, and we're up to 2n total. You need one on the far left, and one on the far right, which brings us up to 2n + 2 toothpicks. Now we need to worry about the middle ones. But notice that you don't need n toothpicks for the interior because adjacent squares share. It turns out that you only need n-1. That brings us up to a grand total of 3n + 1 toothpicks, which would be 301 for n = 100.


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
