Answer:
8 1/8
Step-by-step explanation:
2 4/8 plus 5 5/8
4/8 because it equals to 1/2
1. x/6>3 multiply both sides by 6
x>18
So a. and c. are both greater than 18
2.
-4x<32 divide both sides by -4 (and remember to reverse direction of inequality sign because of multiplication/division by a negative value!)
x>-8
So three value of this infinite set are -7, -6, -5 :P
3.
x/6≥3 multiply both sides by 6
x≥18
So three value of this infinite set of solutions are 18,19,20
suppose the number of boy is x ,so the number of girls is 5/4x,so the total number is 9/4x,we knew the number of total students is 36,so 36=9/4x,x is 16.
Answer:
x = 5, -4
