I cant see anything is it possiable for you go write it out
Step-by-step explanation:
Answer:
C. dL/dt=k(100−L)
Step-by-step explanation:
The rate of change of the number of words memorized is proportional to the number of words left to be memorized.
The rate of change is dL/dt.
The rate is a constant k. Since the rate is proportional to the number of words left to be memorized, and the initial number of words is 100, k has to be multiplied by (100-L).
So the correct answer is:
C. dL/dt=k(100−L)
5x + 4y ≤ 20
5x - 5x + 4y ≤ 20 - 5x
<u>4y</u> ≤ <u>20 - 5x</u>
4 4
y ≤ 5 - 1.25x
Answer:
11 pencils cost £9.35.
Step-by-step explanation:
Given;
7 pencils = £5.95
1 pencil = 5.95 ÷ 7
= £0.85
Now,
11 pencils = 11 × 0.85
= £9.35
