Answer:
Third grade secondary = 87 students
Step-by-step explanation:
First grade = 30/100 x 250 = 75 students
Second grade = 35/100 x 250 = 87.5 rounded off to 88 students. Because students can't be half thus can't be in decimal. So round off to the nearest whole number.
Third grade = 250 - 88 - 75 = 87 students

Answer:
(y-5t)/5=x
Step-by-step explanation:
y=5t+5x
factorize
y=5(t+x)
divide both sides by 5
y/5=5(t+x)/5
y/5=t+x
make x to stand alone
y/5-t=x
take lcm of 5 and 1
y/5-5t/5
y-5t/5=x
