Ok so ratios are poroportion

boys/total=boys/100
total=17+8=25
boys=17
17/25=boys/100
multiply both sides by 100
68=boys


68 boys

So the total number of students equals 8+17 = 25 students
Proportionally:
\frac{17}{25} =  \frac{x}{100}

Thus,
x =  \frac{17*100}{25} = 68 boys out of the 100 students.

Enter the ordered pair that is the solution to the system of equations graphed below.
dalvyx [7]

Answer:

x = 5/2

y = -1/2

Step-by-step explanation:

if both equations start with 'y=' then set the expressions equal to each other

3/5x - 1 = x - 3

add 1 to each side to get:

3/5x = x - 1

subtract 5/5x from each side:

3/5x - 5/5x = -1

-2/5x = -1

multiply each side by -5/2:

x = 5/2

y = 2 1/2 - 3

y = -1/2
