Anything lower than 5 in rounding turns into a zero. The number your rounding stays the same. Therefore the answer is 6 minutes if rounded to the nearest minute.
12.) she gets 70 because she sells 60 fiction and 20 non fiction and you add 60 to 10 because the things are half off
To solve the first question, the angles J and K are perpendicular to each other, that means also that the angles are 90 degrees.
Apart from each other.
This is the total angle measure, that means the sum of the smaller angles must equal 90 degrees.
So the expression would be
2x - 9 + 27 = 90
2x + 18 = 90
2x = 90 - 18
2x = 72
X = 72/2 = 36 degrees.
For the second question since w and v are parallel that means the angles are equal to each other
Thus make the expressions and value equal to each other and solve for x
3x + 60 = 120
3x = 60
X = 20 degrees.
Answer:
$184.72
Step-by-step explanation:
$71.70/3 = $23.09
$23.09*8=$184.72
3 + 12 (y-4) = 40
*Use distribution*
3 + 12y - 48 = 40
*combine like terms*
-45 + 12y = 40
* what you do to one side of the equation you have to do to the other side
-45 +12y = 40
+45 +45
-----------------------
12y = 85
*now you divide to isolate variable*
85
