Answer:
so what are the equations you're having trouble with?
Students total 43430
5742 students more
43430-5742=37688
37688/2 = 18844
ANSWER
Country 1 : 18,844 students
Country 2 : 24,586 students
Explanation: By taking away the 5742 students you set them off to the side. Leaving you with a new sum. You then divide the sum by the number of countries (2). Add the remainder of the students to one of the countries.
B.
X-17=-5
Add 17 to both sides
-5+17=12
Answer:
$295
Step-by-step explanation:
Let d represent the amount Danny contributed. Then Beth contributed (d+80) and Katie contributed ((d+80)-20) = (d+60). The total from the three friends is ...
d + (d+80) +(d+60) = $1025
3d = 885 . . . . . . . . . . . . . . . . . . . subtract 140
d = 295 . . . . . . . . . . . . . . . . . . . . divide by 3; Danny's contribution
Danny contributed $295.
