Hello!

First you have to convert the decimal into a percent

50% = 0.50

Multiply this by the amount of students.

120 * 0.50 = 60

The answer is 60

Write the equation of the graph shown below in factored form. the graph starts at the bottom left and continues up through the x
netineya [11]

For each x intercept the corresponding factor can be deduced. For x intercepts given at 1,2,3 , the equation can be written as

y= (x-1) (x-2) (x-3)

Because x=1 therefore x-1=0 , similarly x=2 , x-2=0 and , x=3 , x-3=0

or

y= x²+2x-3 (x-3)

or

y= x³+2x²-3x-3x²-6x+9

y= x³-x²-9x+9

Alex Ar [27]

Aaron the car wash owner had 228 quarters and 120 dimes.

<h3>Equation</h3>

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of quarters and y represent the number of dimes. Hence:

x = 90% of y + y

x = (0.9y) + y

x - 1.9y = 0   (1)

Also:

0.25x + 0.1y = 69   (2)

From both equations:

x = 228, y = 120

Aaron the car wash owner had 228 quarters and 120 dimes.
