Answer:
Around 120, but 21 times 6 is 126.
Step-by-step explanation:
Since it is known that 20 times 6 is 120, that would be a reasonable estimate because it doesn't account for the ones.
Answer:
Step-by-step explanation:
Let's say that this "certain number" is x. If we are adding that "certain number" to 36, then x+36 equals something. That "certain number," referred to as "it" in the second part, then also must be multiplied by 4 (4x) to get the same result as x+36, therefore:
x+36=4x
-x -x
36=3x
3 3
12=x
Check yourself:
If 12 is added to 36, it equals 48.
If 12 is multiplied by 4, the result is 48 as well.
X-5=-11 =-6 so x=-6.............
Explanation:
The function is
To plot the function in the graph, first we shall determine the amplitude, period, phase shift and vertical shift.
The function is of the form,
where A is the amplitude =
Period is ,
Phase shift is C,
Vertical shift is D.
Hence, from the function , we have,
Amplitude =
Period =
Phase shift = 0
Vertical shift = -2
Now, substituting the values for x, we get the corresponding values for y.

Now, we shall graph the function
Similarly, we shall determine the amplitude, period, phase shift and vertical shift.
Amplitude =
Period =
Phase shift = 0
Vertical shift = 1
Now, substituting the values for x, we get the corresponding values for y in the function

Answer:
x = 9
Step-by-step explanation:
Given
3x - - x = ( add to both sides
3x - x = + = = 25 ← combine x- terms on left side
x = 25 ( multiply both sides by 9 )
25x = 225 ( divide both sides by 25 )
x = 9
