Pls answer these questions. i will give 20 points ad brainliest.
1. write an expression to represent the sum of three consecutive even numbers. let x equal the first number.
2. find the circumference of a circle that has a diameter of 1 4/5 inches. use 22/7 for pi.
3. divide. write the quotient in simplest form. 1/7 divided by -2/7 = ?
you

1. 3x + 6

2. or 7.071

3.

Step-by-step explanation:

1. 3 consecutive even integers

If the first is x, the 2nd is x+2, and the 3rd is x+4

x + (x+2) + (x+4)

= 3x + 6

2. The equation for circumference is

If the diameter is

The the radius is half of that.

So the circumference is

3. To divide we multiply by the reciprocal.  So flip the fraction that we are dividing by.
