x = .
Step-by-step explanation:
Given : 11.42424242 …
To find : Convert it to a rational expression in the form of a over b, where b ≠ 0.
Solution: We have given 11.42424242 …
We can see here two number 42 are repeating.
Let x = 11.42424242 …
On multiplying both sides by 100
100x = 100 * 11.42424242 …
100x = 1142.424242.....
100x = 11.4242.....+1131.00000.....
100x = x + 1131.0000....
On subtracting both sides by x
100x -x = 1131
99x = 1131.
On dividing both side by99.
x = .
Therefore, x = .

x,y - the numbers
one positive number is 5 less than twice a second number
(1) x - 5 = 2y
their product is 117
(2) xy = 117
(1) x - 5 = 2y add 5 to both sides
x = 2y + 5 substitute it to (2)
(2y + 5)y = 117 use distributive property
(2y)(y) + (5)(y) = 117
2y² + 5y = 117 subtract 117 from both sides
2y² + 5y - 117 = 0
2y² + 18y - 13y - 117 = 0
2y(y + 9) - 13(y + 9) = 0
(y + 9)(2y - 13) = 0 ↔ y + 9 = 0 ∨ 2y - 13 = 0
y + 9 = 0 subtract 9 from both sides
y = -9
2y - 13 = 0 add 13 to both sides
2y = 13 divide both sides by 2
y = 6.5
substitute the values of y to (1)
x = 2(-9) + 5 = -18 + 5 = -13 < 0
x = 2(6.5) + 5 = 13 + 5 = 18
Answer: x = 18 and y = 6.5

Answer:

Step-by-step explanation:
There are two rectangles and one triangle. This means that we need to add the sum of two rectangles and one triangle together.
Rectangle 1:
19*9=171
Rectangle 2:
19*9=171
Triangle:
8*23*1/2=32
(We divide by 1/2 because it's a triangle)
Now we add them together.
171+171+32=374
In the end, the answer is 374. I didn't show all of my work because most of it was done mentally.

Answer:
{-1, 3}
Step-by-step explanation:
Please use " ^ " to denote exponentiation: f(x) = x^2 - 2x - 3.
To find the zeros of this quadratic, set it equal to zero first:
f(x) = x^2 - 2x - 3 = 0.
Now factor this result: (x - 3)(x + 1) = 0.
The zeros are {-1, 3}
