Let x = the number.
"increased by" tells you we are adding.
"twice a number" tells you 2 times a number.
16 + 2x = - 24
Subtract 16 from both sides so that we have the variable on one sides and the constants on the other.
2x = - 24 - 16
2x = - 40
Divide by 2 to isolate the variable.
x = - 40/2 = - 20
Your solution is - 20.
To check your answer, plug in.
16 + 2(-20) = - 24
16 - 40 = - 24
- 24 = - 24
Answer:
First of all, rectangles and rectangular prisms have one foremost difference, which is their dimensions. A rectangle has two dimensions whilst a rectangular prism has three. Those dimensions include width, length, and height- but a rectangle has only width and length. Although, in comparison, they're both made from the same quadrilateral: rectangles. A "2D" rectangle has one, while a "3D" rectangle, or rectangular prism, is made of six. The rectangles that make up a rectangular prism can also be referred to as faces.
To divide rational numbers, you turn the division problem into a multiplication problem by flipping the second rational number. Then you go ahead and multiply the tops and bottoms together to get your answer. If you can simplify your problem before multiplication, you can go ahead and do so to make your problem easier.

Answer:
The answer to your question is below
Step-by-step explanation:
1.- 3x + 54 = 5x + 14
3x - 5x = 14 - 54
-2x = - 40
x = 20
2.- I can not see it
3.- Yes, they are paralleles
because 180° = 119 + 61 = 180°
4.-
180° - 82 - 31 = 67°
180° - 67 - 98 = 15°
q = 15°
5.- 100 - x + 30 + 4x + 7x = 180
10x = 180 - 100 - 30
10x = 50°
x = 5
7x = y
y = 7(5)
y = 35°
6.-
55 + 4x + 2x - 5 = 180
6x = 180 - 50
6x = 130
x = 21.7°
7.-
slope = (1 - 2) / (3 - 0)
m = -1 / 3
( y + 1 ) = -1/3(x - 0)
8.-
9.-
slope = 3/7
P (-14 , -3)
( y + 3) = 3/7(x + 14)
10.-
Point (3,2)
A (2, 10)
B (4, 7)
slope = (7 - 10) / (4 - 2)
m = -3/2
New slope = 2/3
(y - 2) = 2/3(x - 3)
