Answer:

131.87-23.24=108.63

Step-by-step explanation:

To solve this problem, let's line up the problem. To make it easier, we can start by ignoring the decimals.

13187

- 2324

______

10863

And then, since there were decimals in the first place, we have to add them back in.

10863→108.63

Which equation has the components of 0 = x2 – 9x – 20 inserted into the quadratic formula correctly? x = StartFraction negative

AnnZ [28]

Answer:

$x=\frac{9+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}$

Step-by-step explanation:

Recall that the quadratic formula gives you the pattern to follow in order to find the solutions to a quadratic equation of the form: $ax^2+bx+c=0$

It tells us that we need to use the parameters $a,\, b,$ and $c$ in the following formula in order to get the answers for the x-values that solve it:

$x=\frac{-b+/-\sqrt{b^2-4\,a\,c} }{2\,a}$

so, in our case, $a=1$ , $b=-9$ , and $c=-20$

then, replacing these values in the formula, we obtain:

$x=\frac{-b+/-\sqrt{b^2-4\,a\,c} }{2\,a}\\x=\frac{-(-9)+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}\\x=\frac{9+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}$

Which looks like the third expression you are listing (although it is a little hard to read)

Solve the inequality. Graph the solution. Describe the graph in the area provided. Be sure to indicate where there is an open or

natka813 [3]

Step-by-step explanation:

The given inequality is :

$-27\ge \dfrac{1}{2}(6x-12)$

Solving RHS of the inequality:

$-27\ge \dfrac{1}{2}\times 2(3x-6)\\\\-27\ge (3x-6)$

Adding 6 both sides of the inequality

$-27+6\ge (3x-6)+6\\\\-21\ge 3x\\\\x\le -7$

The attached figure shows the graph for the given inequality.

Marcus buys a tent priced at $50 if the sales tax is 5% how much tax will Marcus pay

seraphim [82]

5% = 0.05

50 x 0.05 = $2.50

Total tax will be $2.50

Total amount he will pay = 50 + 2.50 = $52.50
