labwork [276]

it is given in the question that

You order two tacos and a salad.the salad cost $2.50.you pay 8% sales tax and leave a $3 tip.

Let the price of taco be $ x .

And 8 % of 2.50 is

$=0.08*2.50 = 0.20$

So the equation is

$2x+ 2.50+0.2+3 = 13.80
\\
2x + 5.70 =13.80
\\
2x = 8.10
\\
x = $4.05$

So the price of the Taco is $4.05 .

At what point in the order of operations should you simplify exponents in an expression?

NemiM [27]

Usually after you do the parentheses and you get to the exponents you do that.

Mathematics can uh solve this please

Answer:

$a^3 + 1 = 0$

Step-by-step explanation:

We start with the equation:

$a + \frac{1}{a} = 1$

We want to find the value of:

$a^3 + 1 =$

We can start with our previous equation and multiply both sides by a:

$(a + \frac{1}{a})*a = 1*a\\a^2 + 1 = a$

Now we can rewrite our initial expression as:

$a = 1 - \frac{1}{a}$

Replacing that in the right side, we get:

$a^2 + 1 = a = 1 - \frac{1}{a}$

Now again, let's multiply both sides by a

$a*(a^2 + 1) = a*(1 - \frac{1}{a} )\\a^3 + a = a - a/a\\a^3 + a = a - 1\\a^3 = -1\\a^3 + 1 = 0$

So we can conclude that:

$a^3 + 1 = 0$
