t20=a+19d.......1

t40=a+39d.......2

t2=a+d=2.........3

According to ques,

t40-t20=a+39d-(a+19d)=40

or,20d=40

or,d=2

Now ,putting the value of d in equation 3,we get,

a=0

t100=a+99d

The answer would be 24pi inches.

You can find this by using the formula for a circumference and plugging in the value of the radius.

C = 2pi*r

C = 2pi * 12

C = 24pi

The length of a line is y centimetres.
ElenaW [278]

Answer:

10y  mm

Step-by-step explanation:

We would need to know the conversion of cm to mm.

We know

1 cm = 10 mm

If we are given a certain amount of centimeters (cm), to get the answer in millimeters (mm), we multiply that by 10. Example:

1 cm = 10 mm

4 cm would be 4 * 10 = 40 mm

23 cm would be 23 * 10 = 230 mm

Now, we are given "y" centimeters.

So, we multiply by "10" to get the answer in millimeters.

Hence,

y * 10 = 10y millimeters (mm)

The line is 10y mm

How do you solve 7x-5=30?
Nadya [2.5K]
7x - 5 = 30

* add 5 to both sides

7x = 30 + 5

7x = 35

* divided both sides by 7

(7/7)x = 35/7

<u><em>x = 5</em></u>
