If its going by $11 for 2 hours then he babysat ?
ok so $11= 2 hours
11 x 3= 33 half of eleven is 5.5
so 33+ 5.5 = $38.50 so I believe the answer is 6 hours and 30 min but I'm not 100 percent positive
2n - 1 - -7n + 2 You combine like terms with subtracting
2n - 7n = -5n
-1 - 2 = -3
So -7n + 2 - 2n - 1 = -5n - 3
3x - 36 + 2x + 26 = 180
5x - 10 = 180
5x = 180 + 10
5x = 190
x = 190/5
x = 38 <==

Step-by-step explanation figure it out yourself di//ckkk/
<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>
