This is #5 Algebra-Find the value for x I know it’s 11 but how do I get there.

Sergeeva-Olga [200]

Answer:

x = 11

Step-by-step explanation:

the line x + 5 is a mid segment of the triangle and thus is half the length of 3x - 1, that is

x + 5 = $\frac{1}{2}$ (3x - 1)

multiply both sides by 2 to eliminate the fraction

2x + 10 = 3x - 1 ( subtract 3x from both sides )

- x + 10 = - 1 ( subtract 10 from both sides )

- x = - 11 ( multiply both sides by - 1 )

x = 11

The probability that the marble on the second draw is blue is also 3/8.

So the probability that both are blue is:

3/8 × 3/8 = 9/64 ≈ 14%
