Y=2x+1 is the right answer to this
Answer:
-x +6
Step-by-step explanation:
We assume you want to simplify this.
Use the distributive property to eliminate the parentheses. That property tells you that the factor outside parentheses (2) will multiply both of the terms inside parentheses. It's as though you had a bag (parentheses) with two objects inside. Two such bags will have two of each of those objects.
2(-x +3) +x
= 2(-x) +2(3) +x
= -2x +6 +x
Now, the like terms -2x and +x can be combined.
= x(-2 +1) +6
= x(-1) +6
= -x +6 . . . . . the simplified expression
Answer:
Probability that one of them is mathematics and other two are either physics or history books = 0.51
Step-by-step explanation:
Given - A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
To find - What is the probability one of them is mathematics and other two are either physics or history books ?
Solution -
Given that,
A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
So,
Total number of books = 3 + 3 + 1 = 7
The student has to select 3 books
So, Total number of ways = = 35
So,
Probability that one of them is mathematics and other two are either physics or history books is -
=
=
=
= 0.51
⇒Probability that one of them is mathematics and other two are either physics or history books = 0.51
Answer:
7 m
Step-by-step explanation:
Circumference of a circle uses the formula;
Circumference = 2 × pi × radius(r)
If the circumference = 44
then we use the formula above to calculate the value of the radius,
44 = 2 × pi × r...then divide both sides by (2 × pi(3.14))
Radius = 44 ÷ ( 3.14 × 2)
;Radius = 7.01
;Radius = 7m
