Answer:
Step-by-step explanation:
They are equal at -40 °C and -40 °F.
F = 9/5C + 32
(F = Fahrenheit and Centigrade)
y = 1/5x
Graph Below:
240 students
Grade 7 : Grade 8 = 5 : 3
Number of seventh grade students = 5x
Number of Eighth grade students = 3x
3x = 90
x = 90÷3
x = 30
Total students = 5x + 3x = 8x = 8 * 30 = 240
