In mathematics, the reciprocal, or multiplicative inverse, of a number x is the number which, when multiplied by x, yields 1. It is denoted 1/x or x-1.
Answer:
If x = 7 y = 20
Step-by-step explanation:
As the x goes up by 1 you see that the y goes up by 2.
y = 2x + 6
Using that equation gets you your y
y = 2(7) + 6
y = 14 + 6
y = 20
Answer:
2+-2+-2=-2
Step-by-step explanation:
The total length of the circle is calculated by the following formula:
Lenght = 2.π.r
As r = 4c
Then,
Lenght = 2.π.4
Lenght = 8π centimetrs
Now use the rule of 3
But we have to know:
...<..> ...
Then,
8π ________ 2π <= 360°
x ________ 3π
2π . x = 8π . 3π
x = (8π . 3π) / 2π
x = (8 . 3π)/ 2
x = 12π centimenters
x ~ 37,69 c
