HACTEHA [7]

Answer:

20x

Step-by-step explanation:

A certain map scale in which 1/2 inch on the map represents an actual distance of 10 miles. A distance of x miles is represented by how many inches on this map?

From the above question:

1/2 inch = 10 miles

x inches = m

Cross Multiply

1/2m = 10x

m = 10x ÷ 1/2

m = 10x × 2

m = 20x

The length of a rectangular piece of steel in a bridge is 2 meters less than triple the width. The perimeter of the piece of ste
Sholpan [36]
This is an algebraic equation. First we have a square the width is X
The length is L=3X-2. P (perimeter is 44)
Therefore P = 2L+2X
                    = 2(3x-2) + 2x
                    = 6x - 4 + 2x
                    = 8x - 4
            44+4=8x
                  x=48/8
                  x=6

Ans: Width is 6 metres and length is 16 metres

klio [65]

Answer:

264,666.

Step-by-step explanation:

We have been given that a number has seven digits.

All digits are 6 except the hundred-thousands' digit.

Hundred thousands: 100,000.

The hundred thousand's digit is 2, so its value would be 200,000.

We have been given that thousands's digit is 4, so its value would be:

4 thousands: 4,000

The number with given hundred thousand's and thousands's digit would be 204,000.

Since all digits are 6 except the hundred-thousands' digit, therefore, our number would be 264,666.
