85 / 15 = 5 2/3
30 x 5 = 150
2/3 x 30 = 20
The answer is 170 seconds, or 2 minutes and 50 seconds
Number of boys:
1000/2+20/2=510
Number of girls:
1000/2-20/2=490
510 boys and 490 girls competed at Special Olympics
It would be 40. youd just add a zero to the end of each number and they add up to 250
2x+3x=180
5x=180
x=180/5
x=36
