Find the ratio a:b if it is given that 2a-b/6 = b/3, then what is a?
PolarNik [594]

Answer:

a = b/4

Step-by-step explanation:

Note that the LCD in this equation is 6. Rewriting 2a-b/6 = b/3 using this LCD, we get:

2a-b/6 = 2b/6

Multiplying all three terms by 6 eliminates the fractions:

12a - b = 2b

Combining like terms:

12a = 3b

                                                       3b

Solving this for a, we get   a = ------------ = b/4

                                                       12

a = b/4

What is the solution to –2(8x – 4) &lt; 2x + 5?
dimulka [17.4K]

Answer:

A. x>\frac{1}{6}

Step-by-step explanation:

We are given the inequality, -2(8x-4)

On simplifying, we get,

-2(8x-4)

i.e. -16x+8

i.e. -18x

i.e. 6x>1

i.e. x>\frac{1}{6}

Thus, the solution of the inequality is x>\frac{1}{6}.

Hence, option A is correct.
