2=-2/7x-6 what is the process

Mathematics
1 answer:
konstantin123 [22]3 years ago
3 0

Answer:

x = - 28

Step-by-step explanation:

Given

2 = - \frac{2}{7} x - 6 ( add 6 to both sides )

8 = - \frac{2}{7} x

Multiply both sides by 7 to clear the fraction

56 = - 2x ( divide both sides by - 2 )

- 28 = x

Make y the subject: <br><br> 5x + 2y = 11
Anton [14]
Does that mean solve for y? If so, here it is:
5x + 2y = 11.

Move the x term by subtracting.
2y = -5x + 11

Divide by 2.
y = -5/2x + 11/2

Answer:

  • 1) 64, 2) 6, 3) 26, 4) 33

Step-by-step explanation:

<h3>#1</h3>

<u>Sum of interior angles is 180</u>

  • 70 + 46 + x = 180
  • 116 + x = 180
  • x = 64
<h3>#2</h3>

<u>Sum of interior angles is 180</u>

  • 84 + 7x + 1 + 9x - 1 = 84
  • 16x + 84 = 180
  • 16x = 96
  • x = 6
<h3>#3</h3>

<u>Vertical angles are same, the sum of remaining angles is same for both triangles:</u>

  • 35 + 25 = 34 + x
  • 60 = 34 + x
  • x = 60 - 34
  • x = 26
<h3>#4</h3>

<u>Exterior angle is same as the sum of non-adjacent interior angles:</u>

  • 5x - 7 + 6x + 3 = 84
  • 11x - 4 = 84
  • 11x = 88
  • x = 8
  • m∠G = 5x - 7 = 5*8 - 7 = 40 - 7 = 33

Find the value of x.<br>need the answer today please.<br>Thank you.​
charle [14.2K]

Answer:

x =8.34654305

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent / hypotenuse

cos 33 = 7/x

Switching places with the x and the 33

x = 7/ cos 33

x =8.34654305
