Over [174]

Answer:

$\large \boxed{\$9.00}$

Step-by-step explanation:

Let p = the original price of the ticket

$\begin{array}{rcl}\text{ Price before discount - discount} & = & \text{sale price}\\p - 0.15p & = & 7.65\\0.85p & = & 7.65\\p & = & \dfrac{7.65 }{0.85}\\\\& = & \mathbf{9.00}\\\end{array}\\\text{The original price of the ticket was $\large \boxed{\mathbf{\$9.00}}$}$

Check:

$\begin{array}{rcl}9.00 - 0.15(9.00) & = & 7.65\\9.00 - 1.35 & = & 7.65\\7.65 & = & 7.65\\\end{array}$

OK.

(4x²-5x+10)+ (6x³+7x²-9x+2) <br> MAKE THIS IN ALGEBRA TILES NONSENSE ANSWER REPORT

ruslelena [56]

Answer:

6x^3+11x^2-14x+12

Step-by-step explanation:

We just simply add like terms (terms with same power of x):

$6x^3+(4x^2+7x^2)+(-5x+-9x)+(2+10)$

Like terms are in brackets now

So you just simplify now to give you:

$6x^3+11x^2-14x+12$
