What is the solution to the equation 2k-10/-7=8

Rasek [7]

$\sf\dfrac{2k-10}{-7}=8$

Multiply -7 to both sides:

$\sf2k-10=-56$

Add 10 to both sides:

$\sf2k=-46$

Divide 2 to both sides:

$\sf~k=-23$

Find the sum of the first 8 terms in the geometric sequence: 1, 3, 9, 27,

Butoxors [25]

The sum of the first 8 items in the geometric sequence:1, 3, 9, 27, ...etc is 3280.

Step-by-step explanation:

The given is,

sequence: 1,3,9,21,.. etc

Step:1

The given is based on multiplication of 3 to previous number,

( x - previous number, next number = 3 × $x$ )

First term : 1

Second term : 1 × 3 = 3

Third term : 3 × 3 = 9

Fourth term : 9 × 3 =27

Fifth term : 27 × 3 = 81

Sixth term : 81 × 3 = 243

Seventh term : 243 × 3 = 729

Eighth term : 729 × 3 = 2187

Step:2

Sum of first 8 terms $= 1 + 3 + 9 + 27 + 81 + 243 + 729 + 2187$

= 3280

Sum of first 8 terms = 3280

Result:

The sum of the first 8 items in the geometric sequence:1, 3, 9, 27, ...etc is 3280.

Clare spent a total of 25 minutes at the track. She spent 5 minutes stretching and walked 4 laps around the track. If she walked

andrezito [222]

Hello!

First of all, we can subtract the stretching time. This gives us 20. If we divide by the four laps we get 5 minutes per lap.

Now, one lap is 400 meters (most tracks are), which is equal to 15,748.03 inches. This means it takes her five minutes to walk 15,748.03 inches. This is also equal to 300 seconds, so it takes her 300 minutes per 15,748.03 inches.

But if we round our big inches number to the nearest ten thousandth, we get 16,000, so in a simpler form her pace is 300/16,000. But we need to find in per second. Therefore we will divide by 300 to find how many inches she walks per second. This means she walks about 53.33 inches per second.

I hope this helps!
