Write an equation with a variable AND solve it. Mario read 72 pages of his book in class and 13 pages per night, n, until he rea
coldgirl [10]

9514 1404 393

Answer:

  72 +13n = 163

  7 nights

Step-by-step explanation:

At 13 pages per night, Mario will read 13n pages in n nights. That plus the pages already read will total 163:

  equation: 13n +72 = 163

__

To solve this, we can subtract 72, then divide by the coefficient of n.

  13n = 91 . . . . . . subtract 72 from both sides

  n = 7 . . . . . . . . divide both sides by n

Mario read 7 nights.

Find the standard form of the circle x2 + y2 – 6x + 10y + 24 = 0 by completing the square.
hichkok12 [17]

Answer:

(x-3)^2+ (y+5)^2=10

Step-by-step explanation:

Given the equation of the circle: x^2 + y^2 - 6x + 10y + 24 = 0

We wish to express it in a Standard form:

We begin by re-arranging:

x^2 - 6x + y^2  + 10y  = - 24

Next, divide the coefficient of x by 2, square it and add it to both sides.

Do the same for y.

x^2 - 6x +(-3)^2+ y^2  + 10y+5^2  = - 24+(-3)^2+5^2

Next, we factorize

(x-3)^2+ (y+5)^2  = - 24+9+25\\(x-3)^2+ (y+5)^2=10

This is the standard form.
