Answer:
£21
Step-by-step explanation:
Cost of 18 drinks = £54
Cost of 1 drink
= Cost of 18 drinks/18
= £54/18
= £3
Cost of 7 drinks
= Cost of 1 drink × 7
= £3 × 7
= £21
When we are partitioning in division, we are dividing the number into its place values, and then applying the divisor to each of the values.
For example in the first problem, we have 642, which is also 600 + 40 + 2.
That means we'll have three division problems.
600 ÷ 2 = 300
40 ÷ 2 = 20
2 ÷ 2 = 1
Which means that 642 ÷ 2 = 300 + 20 + 1, or 321.
You can apply this format to the other two problems to find their answers.
If you do, you should get that 969 ÷ 3 = 323, and 844 ÷ 4 = 211.
Hope this helps!

Answer
In decimal form it is 1.25 and in fraction form it 1/4
Step-by-step explanation:
There might be and there are other ways but the way I did it is I converted the fractions to decimals. 1 3/4= 1.75, 1 1/2= 1.5, and 4 1/2 equals 4.5. So I added the time he practiced on Monday and Tuesday and subtracted it from the final hour of the whole entire week and the answer is 1.25 or 1/4
Answer:
A. On the first day, 3 leaves fall.
B. D. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the previous day.
Step-by-step explanation:
Given

Solving (a) The meaning of 3.
3 represents the initial number of leaves (i.e. the first day) and this proved as follows.
On the first day, n = 0.
Substitute 0 for n in 



Solving (b) The meaning of 2.
2 represents the rate which leaves fall down.
In (a)

Take n = 1
Substitute 1 for n in 



When f(1) is divided by f(0), the result 2. So, the number of leaves doubles everyday
