Answer:

Traslate:

30 - a = 2(a+6)

The number is:

6

Step-by-step explanation:

30 - a = 2(a+6)

30 - a = 2*a + 2*6

30 - a = 2a + 12

30 - 12 = 2a + a

18 = 3a

a = 18/3

a = 6

Check:

30 - 6 = 2(6+6)

24 = 2*12

Help? pre cal, will give points
Viktor [21]

Steps to solve:

5x² = 15x

~Subtract 15x to both sides

5x² - 15x = 15x - 15x

~Simplify

5x² - 15x = 0

~Factor left side

5x(x - 3) = 0

~Factors equal 0

5x = 0 and x - 3 = 0

___________

~Simplify 5x = 0

5x/5 = 0/5

x = 0

~Simplify x - 3 = 0

x - 3 + 3 = 0 + 3

x = 3

___________

Thus, the correct answer is 0, 3.

___________

Best of Luck!

0.5s + 1 = 7 + 4.5s<br><br> Show work, and answers please. This is for algebra 1.
ioda
0.5s + 1 = 7 + 4.5s   Subtract 4.5s from both sides
  -4s + 1 = 7              Subtract 1 from both sides
       -4s = 6              Divide both sides by -4
          s = -\frac{6}{4}   Simplify
          s = -\frac{3}{2}
