Six times the sum of a number and twelve is forty.
Which equation represents this?
6N + 12 = 40
6N + 12N = 40
6(N + 12) = 40
Answer:
6(N+12) = 40
Step-by-step explanation:
6 is multiplying 2 things and that's only possible if there are parenthesis.
6(N+12)
is forty is the answer to the whole equation.
Answer:
6(n+12)=40

If you spun the spinner 1 time, what is the probability
it would land on a gray piece?
Answer:
3/8
Step-by-step explanation:
There are 4 black sections, 3 gray sections, and 1 white section.
This means that there are 8 in total.
3/8 of the squares are gray so that would be the answer.

If the mean of a given dataset is
48 and the standard deviation is
6, where will a majority of the
data lie?
Answer:
between 42 and 54 on the data set
Step-by-step explanation:
standard deviation is the typical variance from the mean so just add and subtract 6 units each direction to get where most of the data is.
Now range of majority:-
[tex]\\ \sf\longmapsto 48-6\to 48+6[/tex]
[tex]\\ \sf\longmapsto 42\to 54[/tex]

the size of an interior angle of a rectangular polygon is(3x)⁹ while the exterior angle is (X-20)⁰.find the number of side of the polygen.
Answer:
12 sides
Step-by-step explanation:
The sum of the exterior angle and the interior angle = 180° , then
3x + x - 20 = 180
4x - 20 = 180 ( add 20 to both sides )
4x = 200 ( divide both sides by 4 )
x = 50
Then
exterior angle = x - 20 = 50 - 20 = 30°
The sum of the exterior angles of a polygon = 360°
The number of sides n is sum divided by 1 exterior angle , that is
n = 360° ÷ 30° = 12

Joan got fast food for lunch. Joan paid $2.41 on a salad and $2.15 on a sandwich
with a $10 bill. Joan got a combo deal. What was the change from the purchase?
Hello :D
To do this you need to add up the cost of the sandwich and salad.
$2.41 + $2.15 = $4.56
$10.00 - $4.56 = $5.44
The answer is $5.44. I hope this helps :)
10 -(2.41+2.15)
10-4.56
5.44 in change
There is a difference of 5 inches in height between CJ and Eric, but you do not know who
is taller. Let c represent CJ's height, and let e represent Eric's height. Formulate an
absolute value equation to relate the heights.
Step-by-step explanation:
The difference between the height of CJ and Eric is 5 inches. It means the height of CJ is either 5 inches higher or 5 inches lower (-5 inches higher) than Eric.
Therefore, we can set up the equation,
[tex]|c-e|=5[/tex]
Alternatively, if we use CJ as the reference,
[tex]|e-c|=5[/tex]

In the grid below, each number can be obtained through the sum of the two numbers connected directly below it. For instance, in the last row, the 5 is the sum of the two numbers below it, 2 and 3. Using the same method, all the numbers starting from the bottom row sums all the way up to the final square, 2x. Determine the value of x if the number in the topmost square is double unknown number in the bottom row.
Answer:
x = -12.
Step-by-step explanation:
Number in the square next to 5 = 3+x.
Number to the right of this one = x + 1
From left to right the umbers in the second row = 5 + 3 + x
and 3 + x + x + 1
= x + 8 and 2x + 4.
So x + 8 + 2x + 4 = 2x
so 3x + 12 = 2x
x + 12 = 0
x = -12.
