Answer:

y = x - 4

Step-by-step explanation:

Given

2y - 2x = -8 -- correct expression

Required

Represent as slope intercept form

2y - 2x = -8

Make 2y the subject

2y = 2x - 8

Divide through by 2

\frac{2y}{2} = \frac{2x}{2} - \frac{8}{2}

y = x - 4

Tom is tiling a wall.
krok68 [10]

Answer:

The correct answer is - £ 40.5 for 3 large packs.

Step-by-step explanation:

Given:

Large pack = 40 tiles £18

Small pack = 28 tiles £14

Special offer = 25% reduction when you buy 3 or more large packs.

Solution:

Following combinations are possible for tom to get the tiles he needs:

1. 3 large packs

40*3 = 120 tiles with 25% discount

cost = 18*3 - 0.25*18*3 = 40.5

2. 4 small packs

28*4 = 112 tiles

cost = 14*4 = 56

3. 2 large packs and 1 small pack

40*2 + 28 = 108 tiles

cost = 18*2 + 14 = 50

4. 1 large pack and 3 small packs

40 + 28*3 = 124 tiles

cost = 18 + 14*3 = 60

Thus, the correct answer is - 1st case with three large packs.

Ella: ratio of rock music to total CDs that she owns 25/40
Paolo: has 50 rock music CDs. The ratio of rock music to total CD is equal to Ella's ratio.

25x = 40 * 50
25x = 2000
25x / 25 = 2000 / 25
x = 80  total of Paolo's CDs

Total of Ella's CDs       =  40
Total of Paolo's CDs   =<u>  80</u>
