Answer:
16 girls in the class
14 boys in the class
Step-by-step explanation:
Because of the ratio of 7:8, I added 7+8.
7+8= 15
30 (the number of students in the class) divided by 15 (the sum of the ratio)
30/15= 2
I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.
Hope this helps!
Answer:
y = (-1/4)x + 9/4
Step-by-step explanation:
2y = 8x - 6
So, y = 4x - 3 (Slope = 4)
Slope of perpendicular line = -1/4
Equation of line: y-3 = (-1/4)(x-(-3))
y-3 = (-1/4)x - 3/4
y = (-1/4)x + 9/4
