The three numbers are x, y, z
The sum of the three numbers = x + y + z = 24
Let the first number = x
The second number is five times the first number = y = (x + 5)
The third number is twice as much as the second number = z = 2y = 2(x + 5)
The sum of these numbers = 24
x + y + z = 24
Substituting the values of y and z in terms of x
x + (x + 5) + 2(x + 5) = 24
x + x + 5 + 2x + 10 = 24
4x + 15 = 24
4x = 24 - 15
4x = 9
x = 9 ÷ 4
x = 2.25
Therefore,
x = 2.25
y = (x + 5) = 2.25 + 5 = 7.25
z = 2(x + 5) = 2(2.25 + 5) = 2 x 7.25 = 14.5
Sum of the three numbers = x + y + z = 2.25 + 7.25 + 14.5 = 24
The correct answer would be Choice D.
I assume you mean to have square root signs in the empty spaces between the numbers.
For choice D, you are adding -4 square roots of 6 and 4 square roots of 6. The answer to that is zero. Which is not an irrational number.
Answer:
A - 220
B - 205
Step-by-step explanation:
29% of 759 is 220.11, round down so it stays 220.
27% of 759 is 204.93 round up so it becomes 205.
bonus:
44% of 759 is 333.96 round up and it becomes 334.
to check your work, add 220, 205, and 334 and its 759. thats how you can be sure its correct.
hope this helps :)
