(3 times 2)-18x+5=47

6-18x+5=47    

6-18x=42    subtract 5 from both sides

-18x=36      subtract 6 from both sides

x=negative 2  Divide by your X

nikklg [1K]

Answer: it will travel 16 miles on each of the remaining days.

Step-by-step explanation:

Total number of miles that the caravan will cross in the desert is 1378. It covered 22 miles on the first day and 28 miles on the second day. Total number of miles which the caravan covered on the first day and second day is 28 + 22 = 50 miles. Total number of miles left to be covered is 1378 - 50 = 1328.

Total number of days left is 85 - 2 = 83.

if the caravan travel the same number of miles on each of the remaining days, the number of miles travelled on each day would be

1328/83 = 16 miles

What is the value of v?
frosja888 [35]

Answer: v = 32 degrees

Step-by-step explanation:

The polygon theorem states that for any polygon with n sides, the sum of the interior angles is (n - 2) × 180

The given polygon has 6 sides. Therefore, n = 6

The sum of the angles in the polygon is

(6 - 2) × 180 = 3 × 180 = 540 degrees

Therefore,

119 + 134 + 108 + v + 47 + 2v + 2v - 28

Collecting like terms, it becomes

119 + 134 + 108 + 47 - 28 + v + 2v + 2v = 540

380 + 5v = 540

5v = 540 - 380

5v = 160

v = 160/5

v = 32 degrees
