4,927 would be the correct answer you just do it on calculator
The number of red marbles in the bag is 19 and the number of blue marbles is 8.
<u>Explanation:</u>
Let R be the number of red marbles
Let B be the number of blue marbles
According to the question,
R + B = 27 (Total number of marbles is 27
) -1
R = 3B - 5 (Number of red marbles is 5 less than 3 times the number of blue marbles
)
Substitute the right half of the second equation for R in the first equation
3B - 5 + B = 27
Add 5 to each side and combine the Bs
4B = 32
Divide both sides by 4
B = 8
Use this value of B in the first equation
R + 8 = 27
R = 19
Therefore, number of red marbles in the bag is 19 and the number of blue marbles is 8.
Answer: 60 different numbers can be formed
Step-by-step explanation:
Note that we have 5 different digits, and we must select 3 of them. They should not be repeated
The order of selection is important in this case, because the number 532 is not the same as the number 235.
So we have a permutations problem, where we have a set of n elements and we want to choose r from them.
Then we define the permutacion as:

In this case note that n=5 because there are 5 elements in the set.
r = 3 because we combine the elements to form three-digit numbers
Then:





Answer:

Step-by-step explanation:

Add 11 to both sides of the inequality to make - 4x stand alone

Divide both sides by - 4

Reverse the signs
We have the final answer as

Answer:
Step-by-step explanation:
The area of a square is the square of the side length. Then the side length is the square root of the area.
- 6² = 36 . . . area of the square of leg 6
- 8² = 64 . . . area of the square of leg 8
- 36+64 = 100 . . . sum of the two leg squares = area of hypotenuse square
- √100 = 10 . . . hypotenuse length
