QUESTION: 1 1/5 = -2 2/3 x +6 solve for x will give brainliest answer quickly or no brainliest.

Whitepunk [10]

Answer: $x=1\frac{4}{5}$

Simplify both sides of the equation

$\frac{6}{5} =\frac{-8}{3} x+6$

Flip the equation

$\frac{-8}{3} x+6=\frac{6}{5}$

Subtract 6 from both sides

$\frac{-8}{3} x+6-6=\frac{6}{5} -6$

$\frac{-8}{3} x=\frac{-24}{5}$

Multiply both sides by 3/(-8)

$(\frac{3}{-8} )*\frac{-8}{3} x)=(\frac{3}{-8} )*(\frac{-24}{5} )$

$x=\frac{9}{5}$

Turn 9/5 into a Mixed Number

$x=\frac{9}{5} =1\frac{4}{5} \\x=1\frac{4}{5}$

The quadratic equation y = –6x2 + 100x – 180 models the store’s daily profit, y, for selling soccer balls at x dollars. The quad

Mrac [35]

Sample response:

points of intersection represent when the price and profit are the same for each type of ball.

The intersection points are approximately

(8.16, 236.49) and (1.84, –16.49).

When the store charges $8.16 for each type of ball, they make the same profit from each ball, approximately $236.49.

Charging $1.88 provides no profit for either type of ball.
