Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

4(x - 1) - 3x = 2

Step 2: Solve for <em>x</em>

  1. Distribute 4: 4x - 4 - 3x = 2
  2. Combine like terms: x - 4 = 2
  3. Add 4 to both sides: x = 6

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

4(6 - 1) - 3(6) = 2

4(5) - 18 = 2

20 - 18 = 2

2 = 2

e-lub [12.9K]

Answer:

2, 7.5

Step-by-step explanation:

2(2x - 1) + 7 < 13

4x - 2 + 7 < 1

4x + 5 < 13

4x < 8

x < 2

-2x + 5 ≤ -10

-2x ≤ -10 - 5

-2x ≤ -15

x ≤ -15 / -2

Answer:

  • x = 5; 85°; 52°; 43°

Step-by-step explanation:

Sum of interior angles of a triangle is 180

  • m∠A + m∠B + m∠C = 180°
  • 17x + 12x - 8 + 8x + 3 = 180
  • 37x - 5 = 180
  • 37x = 185
  • x = 185/37
  • x = 5

Find each angle measure

  • m∠A = 17*5 = 85°
  • m∠B = 12*5 - 8 = 52°
  • m∠C = 8*5 + 3 = 43°
