Answer: x=2

Step-by-step explanation:

I am assuming you are asking which x fits the equation. To see if x works for the equation, you would plug it in.

x=-2

3(-2)+7=13

-6+7=13

1≠13

x=2

3(2)+7=13

6+7=13

13=13

x=5

3(5)+7=13

15+7=13

22≠13

Nancy walked 516 yards in 6 minutes and then another 368 yards in 4 minutes. What was Nancy's average speed? * A. 89 yd/min B. 8
Rina8888 [55]
Average speed = (total distance covered) / (time to cover the whole distance)
 
Total distance = (516 + 368) = 884 yards
Total time  = (6 + 4) = 10 minutes  

Average speed = (884 yards) / (10 minutes)

Average speed = 88.4 yards/minute  (C)


Other ways to write the same speed:

-- 4.42 feet/second
-- 265.2 feet/minute
-- 53.04 inches/second
-- 5,304 yards/hour
-- 3.014 mph (rounded)
-- 810.07 furlong/fortnight

Find the value of x for which the lines rand s are parallel.
erastovalidia [21]

Answer:

x = 12

Step-by-step explanation:

<1 and the 142-deg angle are vertical, so m<1 = 142 deg

The angle measuring 3x + 2 and <1 are same-side interior angles. If the lines are parallel, then those two angles are supplementary.

3x + 2 + 142 = 180

3x + 144 = 180

3x = 36

x = 12

PLEASE HELP ASAP &lt;333<br><br> What is the sum of the geometric series ?
ankoles [38]

Answer:

Step-by-step explanation:

There are a couple of ways to do this. You could figure all four terms out and add them, which is likely the simplest way.

One:     6^(1 - 1) = 6^0 =      1

Two:     6^(2 - 1) = 6^1 =      6

Three:   6^(3 - 1) = 6^2 =   36

Four:     6^(4 - 1) = 6^3 =   216

Sum = 259
