Step-by-step explanation:
4x+2x-10
6x-10
is this something is answer
If this shape is trapezium
m (<D) = m (<C)
since AB parallel to CD
m (<C) + m (<A) = 180°
m (<C) = 180 - 125 = 55°
m (<D) = 55°

Answer:
X = 80
Step-by-step explanation:
A flat line is equal to 180 degrees, meaning that if you use linear, you can find out that if you subtract 100 from it, it becomes 80, which resembles the X.
Answer:
14 9/16 - 8 1/4 = 14 9/16 - 8 4/16 = 233/16 - 132/16 = 101/16 = 6 5/16 ~~ 6
14 9/16 - 8 1/4 = 6
The answer is 20 stamps.
You can solve this by forming an equation with.
We know that she has a total of 50 at the end. So we will put the 50 stamps at the end of the equation and derive for the unknown.
She first gave 10 to her friend. This means we subtract first 10 from the unknown. Let x represent the unknown.
x-10
Afterwards Jane's mom bought her twice as many as she had at the beginning. So we know that we add twice as much as the unknown.
x-10+2x = 50
Now we solve. Let's arrange our terms by combining like terms:
3x - 10 = 50
Now we transpose the 10 to the other side of the equation:
3x = 50 + 10
3x = 60
And finally we transpose the 3 by the x to isolate x:
x = 60/3
= 20
She had 20 stamps in the beginning.
