Mathematics

Solution:

<u>Note that:</u>

  • 3x + 50 = 6x - 10 (Vertically opposite angles)

Simplify the equation to find x.

<u>Add 10 both sides.</u>

  • 3x + 50 = 6x - 10
  • => 3x + 50 + 10 = 6x - 10 + 10
  • => 3x + 60 = 6x

<u>Subtract 3x both sides.</u>

  • 3x + 60 = 6x
  • => 3x - 3x + 60 = 6x - 3x
  • => 60 = 3x

<u>Divide 3 both sides.</u>

  • 60 = 3x
  • => 60/3 = 3x/3
  • => x = 20

Answer:

<h2><u><em>x = 20</em></u></h2>

Step-by-step explanation:

opposite angles = equal angles

we solve with a proportion

3x + 50 = 6x - 10

50 + 10 = 6x - 3x

60 = 3x

x = 60 : 3

x = 20

Ksenya-84 [330]

Length (L): L

width (w): (2/3)L

Perimeter (P) = 2L + 2w

               390 = 2(L) + 2(2/3)(L)

               1170 = 6L + 4L

               1170 = 10L

                  117 = L

width (w): (2/3)L   = (2/3)(117) = 2(39)   = 78

Answer: width = 78 ft, length = 117 ft

I WILL GIVE BRAINLIEST!!!
Basile [38]
I have returned!

36 can technically be either A or B, although A works better. The workers are trying to see which type of vegetables sell better, and it’s easier to see which bar is taller rather than which slice is bigger.

37 would be the median, or the middle of all the values. The median is 30 (two smaller and two bigger values), while the range is 27 (32-5, range of values), the mode is 5 (the value that occurs the most), and the mean is 20.6 (average of all values). The median is the only value larger than 30, so this would be the best one to tell his parents.
