-6n-20=-2n+4 (1-3n)
how do you solve it?
Answers
Simplify both sides of the equation.
−6n−20=−2n+4(1−3n)
−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)
−6n+−20=−2n+4+−12n
−6n−20=(−2n+−12n)+(4)(Combine Like Terms)
−6n−20=−14n+4
−6n−20=−14n+4
Add 14n to both sides.
−6n−20+14n=−14n+4+14n
8n−20=4
Add 20 to both sides.
8n−20+20=4+20
8n=24
Divide both sides by 8.
8n/8 = 24/8
n=3
-6n - 20 = -2n + 4 - 12n
-6n + 12n + 2n = 4+20
8n = 24 |:8
n=3

Answer:
Step-by-step explanation:
Start with 180-38. That gives us 142. We know that 2 of the sides are the same so the two missing values are split evenly between 142. Angle 2 is 71.
71=x+84
subtract 84 from both sides
x=-13

Answer:
C) Square, Rhombus and Kite
Step-by-step explanation:
These are due to the fact that the square has all its equal sides and is 4 sides, so its diagonals will always be perpendicular.
The rhombus also has all its equal sides and are 4 sides so its diagonals will always be perpendicular.
The kite does not have its four equal sides, but its vertices are constructed from its diagonals that cross perpendicularly, so it also meets the perpendicular diagonals
The quadrilaterals have perpendicular diagonals are:
C) Square, Rhombus and Kite.
Here, we have,
These are due to the fact that the square has all its equal sides and is 4 sides, so its diagonals will always be perpendicular.
The rhombus also has all its equal sides and are 4 sides so its diagonals will always be perpendicular.
The kite does not have its four equal sides, but its vertices are constructed from its diagonals that cross perpendicularly, so it also meets the perpendicular diagonals.
Diagonals are the part of a shape, in geometry.
In Mathematics , a diagonal is a line that connects two vertices of a polygon or a solid, whose vertices are not on the same edge. in general, a diagonal is defined as a sloping line or the slant line , that connects to the vertices of a shape. diagonals are defined as lateral shapes that have sides/ edges and corners.

Final answer:
The total cost of Dara's purchases was $38.07. Upon subtracting this amount from her initial $50, she is left with $11.93 change.
Explanation:
To solve the problem, you need to add up how much Dara spends and subtract that from $50. First, add the cost of the sandals, shorts, and hat together:
- $13.02 for sandals
- $9.85 for shorts
- $15.20 for the hat
When you add these three amounts together, you get $38.07. So, Dara has spent $38.07 in total. Now, subtract that amount from $50:
$50.00 - $38.07 = $11.93
This means Dara should get back $11.93 in change.
