Answer:
(-8/7 ; 5/7)
Step-by-step explanation:
5t + 1/2s = 3 - - - (1)
3t - 6s = 9 - - - - - (2)
Multiply (1) by 12 and (2) by 1
Add the result to eliminate s
60t + 6s = 36
3t - 6s = 9
____________
63t = 45
t = 45 / 63
t = 5/7
Put t = 5/7 in either (1) or (2) to obtain the value of s
3(5/7) - 6s = 9
15/7 - 6s = 9
-6s = 9 - 15/7
-6s = (63 - 15)/7
-6s = 48/7
s = 48/7 * - 1/6
s = - 8/7

Answer: 2.2464 × 10^8
Step-by-step explanation:
Percentage of obese Americans in 2011 - 2012 = 35%
Percentage of Americans who are adult = 72%
United States population estimate = 312 million
Adult = age 20 and above
Number of adult Americans (age 20 and above) :
72% of the total united states estimated population
72% of 312,000,000
72/100 × 312,000,000
0.72 × 312,000,000
= 224,640,000
Hence, estimated Adult American population (age 20 and above) = 224,640,000
2.2464 × 10^8
