Answer:

The answer to this equation would be <u>B. 6!</u>

Step-by-step explanation:

  1. 2x + 3 = 15
  2. Subtract 3 from left and right side. Variable needs to  be left alone. 15 will turn into 12. <em>  </em>
  3. <em>2x = 12 </em>
  4. <em>x= 6 since 2 x 6 = 12 or divide 12 by 2 and get  6</em>

<em>Check Answer:</em>

<em>2(6) + 3 = 15</em>

<em>2x6 =12</em>

<em />

<em>12 + 3 =15 </em>

A+b/a-b=5/3 what are the following ratios? 3a:2b
Papessa [141]

Answer:

3 a : 2 b = 6 : 1

Step-by-step explanation:

<em>\frac{a + b}{a - b} = \frac{5}{3}</em>

<em>3 ( a + b) = 5 ( a - b) </em>

<em>3 a + 3 b = 5 a - 5 b </em>

<em>5 b + 3 b = 5 a - 3 a </em>

<em> 8 b = 2 a </em>

<em> 2 a = 8 b</em>

<em><u>a = 4 b</u></em>

<em>3 a = 3 × 4 b</em>

<em><u>3 a = 12 b</u></em>

<em>3 a: 2 b = 12 b : 2 b</em>

<em>3 a : 2 b = 6 : 1</em>
