Answer:
Step-by-step explanation:
"Five times a number" is '5x'.
"Decreased by nine is" '-9'.
"Is equal to" is '='.
"Twice the number" is '2x'.
"Increased by 23" is '+ 23'.
Put them together: 5x-9=2x+23
5x - 9 = 2x + 23 should be the correct answer.
Answer:
The distance is 4 units.
Step-by-step explanation:
Let the distance between the two points (x₁, y₁) and (x₂, y₂) is
<em>d = √(x₂ - x₁)² + (y₂ - y₁)²</em>
Here, the given points are (2,8) and (6,8), therefore,
x₁ = 2, x₂ = 6,
y₁ = 8, y₂ = 8
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(6 - 2)² + (8 - 8)²
d = √(4)² + (0)²
d = √16
d = 4
Thus, The distance is 4 units.

Answer:
The estimate of the proportion of all students that prefer to use a metal pen is 0.4.
Step-by-step explanation:
The estimate of the proportion is the sample proportion.
In the sample:
10 students
4 use a metal pen. So

I would say C but I’m not completely 100% sure
Answer:
A reasonable estimate is [tex]1,900 * 300 = 570,000[tex]
Step-by-step explanation:
This is because 1,900 is the closest multiple of 100 for 1,912, and 300 is the closest multiple of 100 for 305. And [tex]1,900 * 300[tex] is [tex]19 * 3 * 10,000[tex].
