Step-by-step explanation:

Given : The expression 60(1+x) represents the total bill including the tip.

To find : What do the different parts of the expression represent?

Match each expression to the correct description.

1) Cost of meal __

2) Tip percentage __

3) Number of friends __

Solution :

The expression represents the total bill including the tip is 60(1+x).

When we see the expression,

The cost of the mean is always fixed.

So, Cost of the meal is 60.

Number of friends is unknown.

So, Number of friends is 'x'.

The tip percentage is given by '1+x'.

I need step by step help with: 3x^1/3 + 2x^2/3 =5

Luba_88 [7]

If you write $y=x^{1/3}$ , you'll notice this is really just a quadratic equation that can be factorized:

$2x^{2/3}+3x^{1/3}-5=0\iff 2y^2+3y-5=0\iff (2y+5)(y-1)=0\iff(2x^{1/3}+5)(x^{1/3}-1)=0$

So you have

$2x^{1/3}+5=0\implies 2x^{1/3}=-5\implies x^{1/3}=-\dfrac52\implies x=-\dfrac{125}8$

and

$x^{1/3}-1=0\implies x^{1/3}=1\implies x=1$
