Solve for X in the rectangle?
Answers
Answer:
x=6
Step-by-step explanation:
13x+12=90
13x=78
x=6
The value of x in the rectangle is 6.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given quadrilateral is a rectangle.
In rectangle each angle has 90 degrees.
So equate 13x+12 and 90 degrees to get x
13x+12=90
Subtract 12 from both sides
13x=90-12
13x=78
Divide both sides by 13
x=6
Hence, the value of x in the rectangle is 6.

Which digit(s) make the solution of the equations the whole number? 5x-496=1.34...
Answers
Answer:
x≈ 100
Step-by-step explanation:
Given the equation
5x-496=1.34...
We are to find the value of x to the nearest whole number
Add 496 to both sides
5x-496+496 = 1.34+496
5x = 497.34
x = 497.34/5
x = 99.468
x ≈ 100
Hence the value of x to nearest whole number is 100

Answer:0.75757575757
Answer:
Fraction Form
25/33
Decimal Form
0.75
Step-by-step explanation:
First, convert the mixed fraction into an improper fraction, so it would look like:
-5/3 / (-11/5)
Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:
5/3 x 5/11
Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

Answer:
the second one
Step-by-step explanation:
in order for it to be a function the x values CANNOT repeat.
in answer a the x value -6 repeats so that cannot be a function
in answer b none of the x values repeat so its probably this one but lets check the other ones just in case
in answer c the x value 8 repeats so it cannot be this one
in answer d the x value -2 repeats so it cant be this one \
b is the only one that does have repeating x values therefore it is the second one
