5x -2y = 26. We know that x = y + 4. Substitute the value of x in and you get 5y + 20 - 2y = 26 If yous simplify this you get 3y + 20 = 26
Take away 20 from both sides and you end up with 3y = 6
Now did use both sides by 3

You end up with y = 2
Now to find x you just simplify the value of y into x = y + 4. You end up with x = 2 + 4. Now you know that y = 2 and. X = 6

You buy the following materials for the new extension. Calculate the cost of the bricks and cement and then work out the total c
bogdanovich [222]

<u>Answer:</u>

Cost of sand = £150

Cost of bricks =  £157.5

Cost of cement = £134

Total cost = £441.50

<u>Step-by-step explanation:</u>

We are given that:

2 tonnes of sand  is for £75.00 per tonne,

20 bags of cement  are for £6.70 per bag,

350 bricks at 45p each,

So, 2 tonnes of sand  at £75.00 per tonne = 2 * £75.00 = £150.00

20 bags of cement  at £6.70 per bag = 20 * £6.70 = £134.00

350 bricks at 45p each = 350 * £0.45 = £157.50

Therefore, the total cost of all the materials = £150 + £134 + £157.5 = £441.50
