Answer:
The full question is attached in the picture below.
The better price for the battery is given with the 6 pack.
(£ 0.47 per battery)
Step-by-step explanation:
If 8 batteries cost £ 3.99
This means that one battery is equal to
£3.99/8 = £ 0.49875 ≈ £ 0.50 per battery
The pack of 6 batteries costs £ 2.79
This means that one battery is equal to
£2.79/6 = £ 0.465 ≈ £ 0.47 per battery
Then, we can conclude than the 6 pack gives us a better price per battery
4y + 3 ≤ y + 6
4y + 3 - 3 ≤ y + 6 - 3
4y ≤ y + 3
4y - y ≤ y - y + 3
3y ≤ 3
3y/3 ≤ 3/3
y ≤ 1
So any value of y less than or equal to 1 (so 1 is included in the solution set) satisfies the inequality. C is the correct answer.
Answer:
The total area:
12 units²
Step-by-step explanation:
There are three parts on this shape:
1 big right triangle
1 rectangle
1 small right triangle
area = (4*4)/2 = 16/2 = 8units²
area = 2*1 = 2units²
area = (2*2)/2 = 2units²
8+2+2 = 12 units²
