 <span>Assuming the seven rods are arranged such that the 7th rod is surrounded by the other 6, then the strap must have a length equalling 2.5 cm + 6 * 1.8 cm + 2 * pi * (1.8/2)^2 cm which is 
13.3 + pi * 1.62 cm or approximately 18.4 cm to 1 decimal place.

Using the equation y = 2x – 3, what would the input need to be for an output of 7?
Keith_Richards [23]

Answer:

5

Step-by-step explanation:

We have an equation and are asked to find the input of x when y = 7.

The output = y = 7

The input = x

7 = 2x - 3

2x - 3 = 7

We need to find a number that multiplied by 2 which then is subtracted by 3 equals 7. We can use the backwards method  to solve our answer.

2x - 3 = 7

7 + 3 = 2x

10 = 2x

Solve for x by dividing 2 from both sides :

x = 5.

Therefore, you would need an input of 5 to get 7 as the output.

Proof :

2(5) - 3 = 7

10 - 3 = 7
