Answer 1

Answer:

Answer:

2520 stones which will cost £6300

Step-by-step explanation:

First find area of path:

630 x 120 = 75600 cm²

then find how many stones will be needed:

75600/30 = 2520

then find out the total cost:

2520 x 2.5 = £6300

Hope this helps!

Answer 2

Answer:

Answer:

£125

Step-by-step explanation:

First, find perimeter.

630 + 630 + 120 + 120 = 1500

Divide by stone width.

1500 / 30 = 50

Multiply by the cost.

50 x 2.5 = 125

The lesser of two consecutive even integers is 10 more than one-half the greater. Find the integers.

Answers

Hello,

Here's my solution:

Let n = the lesser of the two consecutive even integers; so what will be a good way to represent the greater of the two consecutive even integers? I say n + 2.

Let's write the equation:
n = ((n+2)/2) + 10

I'll multiply both sides of the equation by 2 to eliminate the denominator, getting:
2n = 2[((n+2)/2) + 10]

This reduces to:
2n = n+2 + 20

Which can be further simplified to:
2n = n+22

Subtracting n from both sides we get:
n = 22

So n, the lesser consecutive even integer is 22. The greater consecutive even integer is 24.

Let's check this solution by substituting n = 22 into our original equation:

n = ((n+2)/2) + 10

22 = ((22+2)/2) + 10
22 = ((24)/2) + 10
22 = (12) + 10
22 = 22 - it checks!
