Answer:
x<-6
Step-by-step explanation:
(19 + 28 + 62 + 51 + x) / 5 = 38
(160 + x) / 5 = 38
160 + x = 38 * 5
160 + x = 190
x = 190 - 160
x = 30 <== age of 5th person
<span>h(t) = 210 – 15t models the altitude of a hot air balloon over time t, in minutes
means that at time t min, the height h of the balloon is 210-15t (units)
for example,
at time t=1 min, the height of the balloon is 210-15*1=195 (units)
at time t=2 min, the height of the balloon is 210-15*2=210-30=180 (units)
Thus, h(10) is the height of the balloon at time t=10 min,
h(10)=210-15*10=210-150=60</span>
