For this case, the first thing we must do is define variables.
We have then:
x: number of trips.
y: amount of money remaining.
We now write the equation for each person.
For Kaisorn we have:
Pata Thom we have:
Answer:
The system of equations that represents this situation is given by:
Answer:
Option 3 3 1/8x - 6 3/10
Step-by-step explanation:
(3 1/2x - 4 1/10) - (3/8x + 2 1/5)
Divide it into parts:
(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)
3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x
-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10
So we get:
2 1/4x - 6 3/10
<span>since h=2t+3
i.e. at h=13 we find
13= 2t+3
i.e. 13-3= 2t
10=2t
i.e. t=10/2
i.e. t=5 days
similarly at h=27
we find
27= 2t+3
i.e. 27-3= 2t
24=2t
i.e.
t=24/2
i.e.
t=12 days
hence in 5 and 12 days the height of the tomato plant will be between 13 and 27 inches respectively.</span>
Answer:
H >= 6.25
6.5 hours per week
Step-by-step explanation:
75-50=25
JT must complete 25 more hours of exercise in 4 weeks. 25/4=6.25. So JT has to exercise 6.5 hours each week.
>= (means greater than or equal to)
