If it costs £55 to buy 11 cushions, how much will it cost to buy 19?

£95

Step-by-step explanation:

Cost of 11 cushions = £55

Unit cost of 1 cushion = 55/11 = £5 per cushion

Cost of buying 19 cushion = 19 × unit cost

= 19 × £5

= £95

Thus, it would cost £95 to buy 19 cushions

Step-by-step explanation:

11 cushions = £55

1 cushion = 55 ÷ 11

1 cushion = £5

19 cushions = £5 × 19

= £95

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
