a seven sided number cube with sides numbered 1,2,3,4,5,6,7 is rolled. what is the probability that a 4 or odd number is rolled ? which fraction ? 5/7 2/7 3/7 4/49
The probablity of rolling a 4 = 1/7
There are 4 odd numbers, so the probablity of rolling an odd number = 4/7
4/7 + 1/7 = 5/7
Which one is it? Help
The answer would be letter B.
Find variable of b + 25 = b —25
Answer:
There is no solution
Step-by-step explanation:
Simplifying
b + 25 = b + -25
Reorder the terms:
25 + b = b + -25
Reorder the terms:
25 + b = -25 + b
Add '-1b' to each side of the equation.
25 + b + -1b = -25 + b + -1b
Combine like terms: b + -1b = 0
25 + 0 = -25 + b + -1b
25 = -25 + b + -1b
Combine like terms: b + -1b = 0
25 = -25 + 0
25 = -25
Solving
25 = -25
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Answer:
There are no values of b no solution that makes the equation true.

Dave is driving to Dallas, TX for the weekend from Austin, TX for the weekend. He is traveling along the tollway 130. The speed limit is 80 mph. There are approximately 1.6 kilometers in 1 mile. What is this limit in kilometers per hour?
We need to multiply the 80mph by the 1.6 to make it KPH
When done correctly we get the answer of 128KPH
The limit is 128kph

Please help Factor the expression using the GCF the expression 32z-48 factored using the GCF is
Answer:
16(2z -3)
Step-by-step explanation:
There are two ways of solving this problem.
List out the factors of the numbers:
32z - 48
= 32 * z - 48
32= 1, 2, 4, 8, 16, 32
48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
the largest common factor that both numbers have in common is 16,
So factoring the equations means the one has to divide the equation by 16 and write it outside of the parenthesis.
16 * ( 2 * z - 3)
16(2z -3)
Another way of solving the problem:
prime factorize the number:
32 = 2^5
48 = 2^4 * 3
Both numbers have 2^4 as their largest factor in common meaning that that is their GCF. 2^4 is 16.
Now factor out 16 and write it on the outside of the parenthesis.
16 * ( 2 * z - 3)
16(2z -3)
Answer:
16(2z -3)

Simon is making a poster about friendship in his art class. He divides his poster into 3 equal parts. Simon writes the names of his friends all over each part. Simon uses 1 part for his neighborhood friends and 1 part for his friends from school.
What fraction of the poster does Simon use for his friends from school?
Answer:
1/3
Step-by-step explanation:
The most important thing to remember is that the poster is divided into three equal parts and 1 part of it is for his neighborhood friends and another one part of it is for his friends from school. The denominator would be three and the numerator would be the 1 part he uses for his friends from school.

Solve 3x -12 = 24.
Please help!
Answer:
12
Step-by-step explanation:
3x - 12 = 24
Add 12 to both sides to make 3x the subject of the equation.
3x - 12 (+12) = 24 (+12)
3x - 0 = 36
3x = 36
Divide both sides by 3.
3x/3 = 36/3
x = 12
Please give brainliest, rate 5 stars, and thank. Thank you
The required solution to the given equation 3x -12 = 24 is x = 12.
What is the algebraic equation?Algebraic equations are mathematical statements with a minimum of two terms containing variables or numbers that are equal.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The given equation is given in the question
⇒ 3x - 12 = 24
Add 12 to both sides of the above equation
⇒ 3x - 12 (+12) = 24 (+12)
⇒ 3x - 0 = 36
Apply the subtraction operation,
⇒ 3x = 36
Divide both sides by 3.
⇒ 3x/3 = 36/3
⇒ x = 12
Therefore, the required solution to the given equation 3x -12 = 24 is x = 12.
