Please help me. solve for X

Mathematics
1 answer:
Vinil7 [7]3 years ago
6 0

Answer:

1. x = 16

2. x = 17

Step-by-step explanation:

1. The sum of the exterior angles of any polygon is 360 degrees. So, to find x, we can add up all of the angle measures and set them equal to 360, then solve for x:

46 + 93 + 47 + 4x + 62 + 3x = 360

Combine like terms:

248 + 7x = 360

Subtract 248 from both sides of the equation to isolate 7x:

7x = 112

Divide both sides by 7 to find the value of x:

x = 16

2. The sum of the interior angles for a 5-sided polygon is 540 degrees. So, to find x, we can add up all of the angle measures and set them equal to 540, and then solve for x:

5x + 139 + 9x + 71 + 92 = 540

Combine like terms:

14x + 302 = 540

Subtract 302 from both sides to isolate the 14x:

14x = 238

Divide both sides by 14 to find the value of x:

x = 17

I hope this helps :)

What is the answer if <br> Increase 12% by 30%
mrs_skeptik [129]

Answer:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

30% = 30/100 = 30 ÷ 100 = 0.3.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 30% of its value.

Calculate the New Value

New value =

12 + Percentage increase =

12 + (30% × 12) =

12 + 30% × 12 =

(1 + 30%) × 12 =

(100% + 30%) × 12 =

130% × 12 =

130 ÷ 100 × 12 =

130 × 12 ÷ 100 =

1,560 ÷ 100 =

15.6

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 12 =

15.6 - 12 =

3.6

16h - 9 = -13 - 6h - 18<br><br> h=
densk [106]

Answer:

h = -1

Step-by-step explanation:

Solve for h:

16 h - 9 = -6 h - 31

Add 6 h to both sides:

16 h + 6 h - 9 = (6 h - 6 h) - 31

6 h - 6 h = 0:

16 h + 6 h - 9 = -31

16 h + 6 h = 22 h:

22 h - 9 = -31

Add 9 to both sides:

22 h + (9 - 9) = 9 - 31

9 - 9 = 0:

22 h = 9 - 31

9 - 31 = -22:

22 h = -22

Divide both sides of 22 h = -22 by 22:

(22 h)/22 = (-22)/22

22/22 = 1:

h = (-22)/22

The gcd of -22 and 22 is 22, so (-22)/22 = (22 (-1))/(22×1) = 22/22×-1 = -1:

Answer:  h = -1
