Write 2.71 as a simplified fraction.
Answer:
[tex] \frac{271}{100} [/tex]
Step-by-step explanation:
hopefully it makes sense
:)
The decimal 2.71 can be written as the simplified fraction as 271/100.
What are Fractions?Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.
Here p, called the numerator and q, called the denominator, are real numbers.
The given number is 2.71.
We can write 2.71 as 2.71 / 1, since any number divided by 1 is the number itself.
Multiplying both numerator and denominator of 2.71 / 1 with 100, we get,
(2.71 × 100) / (1 × 100)
= 271/100
This cannot be simplified further since 271 is a prime number.
Hence the simplified fractional form of 2.71 is 271/100.

Step-by-step explanation:
Given
- 3(- 5x + 2) + x - 3 = 39 ← distribute parenthesis and simplify left side
15x - 6 + x - 3 = 39
16x - 9 = 39 ( add 9 to both sides )
16x = 48 ( divide both sides by 16 )
x = 3

HELPPPP PLSSS You start at (3, -5). You move left 4 units and right 4 units. Where do you end? 4 3 IC 1 Х F -5 -4 -3 -2 -1 0 1 3 5 N -2 ܚ ܛ -5
Answer:
here you go :)
Step-by-step explanation:
You can approach this problem by thinking about going in the opposite of the directions indicated starting at the point (3, 4).
If you ended at an x-coordinate of 3 after having moved 4 to the left, then you can start at 3 and move 4 to the right to see what x -coordinate you started at: 3 + 4 = 7
The x coordinate of the STARTING point would have been 7.
You can do the same with the y-coordinate: start at 4 and travel down 1 unit. The y-coordinate of the STARTING point would be 3.
Therefore, the coordinates of the starting point would have been (7,3)
I subtract 14 from a certain number I multiply the result by 3 the final answer is 3 what was the number
Answer:
15.
Step-by-step explanation:
3(x - 14) = 3
3x - 42 = 3
3x = 42 + 3 = 45
x = 15.
Let the number = x
Set up the equation:
3(x-14) = 3
Simplify:
3x -42 = 3
Add 42 to both sides
3x = 45
Divide both sides by3
X = 15
The number is 15

f(x)=x^2+12x+34
Answer:
(-6, -2)
Step-by-step explanation:
[tex]f(x) = {x}^{2} + 12x + 34[/tex]
[tex] = f(x) = {1x}^{2} + 12x + 34[/tex]
= a = 1, b = 12
[tex] = x = - \frac{12}{2 \times 1} [/tex]
[tex] = x = - \frac{12}{2} [/tex]
= x = -6
[tex] = f(x) = {x}^{2} + 12x + 34.. = - 6[/tex]

Find the area of the following quadrilateral.
Answer: 480
Step-by-step explanation:
The quadrilateral ABCD is a trapezium
The formula for area of trapezium is
Area of trapezium = 1/2 × (parallel side 1 + parallel side 2) × h
So we can place the given values into the formula.
We get
Area = 1/2 × (9+15) × 40
Area = 1/2 × 24 × 40
By multiplying all of them we get
Area = 480cm
