Answer:

Step-by-step explanation:

Let us say, Olivia's age is x.

Now as the question says, we will get this equation.

$( \frac{1}{3} x ) + 12= 2x - 3$

Multiply both sides by 3.

$x + 36 = 6x - 9$

Collect like terms.

$x - 6x = - 9 - 36$

Calculate.

$- 5x = - 45$

Divide both sides of the equation by -5.

$x = 9$

Then, we will get the answer.

I hope it helps.

Find the value of the variable and BC, if B is between A and C. AB = 5x, BC = 3x-1, AC = 47

schepotkina [342]

Answer:

Step-by-step explanation:

AC = AB + BC

Since we know what each variable equals, we can write out the equation as shown:

47 = 5x + 3x - 1

Combining like terms:

47 = 8x - 1

Add 1 on both sides:

48 = 8x

Divide 8 on both sides:

X = 6

Now that we know what X equals, we can solve BC.

BC = 3(6) - 1

BC = 18 - 1

BC = 17

Therefore BC = 17.
