Answer: you just multiply the big by the percentage. But change the percentage to a decimal. There only two operating when dealing with percentage. Add or subtract. Once you multiply the percentage with big number add or subtract the answers with the big number.
Step-by-step explanation:
Answer:
1. About 9 left. 2. £21 left
Step-by-step explanation:
First, you do 65 ÷ 3 = 21.7 if rounding to the tenths, 21.67 if to the hundredths, and so on. Then you do 21.67 - 12 = 9.67. But since it is cards, I would say about 9 left.
First you add the £20 to the £70 to get £90. then you multiply 7×3 to get £21 spent on books. After that, multiply 12×4 to get £48 spent on games. then do 48 + 21 = 69. 90-69= 21.
Here is the equation....
(70+20)-[(7×3)+(12×4)] = £21
Let us assume the number of movies for ehich the cost of both companies becomes the same = x
Then
55 + 4x = 110
4x = 110 - 55
4x = 55
x = 55/4
= 13.75
So
The number <span>number of movies for which the cost of Carl's cable company is less than the cost of Teleview = 13.
I hope the procedure is clear enough for you to understand and this is the answer that you were actually looking for.</span>

Sin (A) = BC/AB = 21/75= 7/25
