You add all the numbers together and divide by the amount of numbers
Answer:
Step-by-step explanation:
7/12
no. of not prime number/ total no. of number
50% is
We have two ways to do this, pick your favor:
either by fractions:
÷
(
Multiply by the reciprocal of
which is 2(flip it)
× 2 =
= 1.25
Or change them to decimals:
= 0.5
0.625 ÷ 0.5
0.5 I 0.625
multiply by 10 to make it easier to divide(it still gives us the same answer)
0.5 × 10 = 5
0.625 × 10 = 6.25
1.25
5 I 6.25
-5
12
-10
25
-25
0
0.625 ÷ 0.5 =
1.25
Answer:
21x-28
Step-by-step explanation:
Given:
The distance between the two points (11, 1) and (x, 17) is 20.
To find:
The possible values of x.
Solution:
Distance formula is:
Using this formula, the distance between (11, 1) and (x, 17) is
Taking square on both sides.
Splitting the middle term, we get
Using zero product property, we get
Therefore, the possible values of x are -1 and 23.
