Answer:

x=−0.714286

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2.5(−2−3x)+2.5(−4x−1)=−2x−4x

(−2.5)(−2)+(−2.5)(−3x)+(2.5)(−4x)+(2.5)(−1)=−2x+−4x(Distribute)

(7.5x+−10x)+(5+−2.5)=(−2x+−4x)(Combine Like Terms)

Step 2: Add 6x to both sides.

Step 3: Subtract 2.5 from both sides.

Step 4: Divide both sides by 3.5.

x=−0.714286

Rewrite the equation by completing the square x^2+12x-13=0

mote1985 [20]

Answer:

$(x+6)^{2}-49$

Step-by-step explanation:

In order to complete the square, you want to convert a quadratic from the form -

$ax^{2}+bx+c$

to the form-

$a(x+d)^{2}+e=0$

If you're in a hurry,

$d=\frac{b}{2a}\\e=c-\frac{b^{2}}{4a}$

and you can convert from there.

A hair cut cost $25 and you want to leave a 15% tip what is the total bill?

Olin [163]

You need to change 15% to a decimal and multiply it by 25

25 x 0.15 = 3.75

Then add 3.75 to 25 to get the total

25 + 3.75 = 28.75

So, the answer is 28.75$

Hope it helps :)
