Answer:
XQ = 12
Step-by-step explanation:
In this question it asks for XQ instead of x, but you need to find x first.
1. Find x.
XQ is half of MQ so this statement is true: 3x - 3 = 2(2x - 6)
Solve for x.
3x - 3 = 2(2x - 6)
Distribute 2.
3x - 3 = 4x - 12
Isolate x.
3x = 4x - 9
-x = -9
Divide -1 out.
x = 9
Now solve for XQ, which the equation is given.
XQ = 2(9) - 6
XQ = 18 - 6
XQ = 12
In general you can multiply through by the LCD
For example solve :-
2/x + 1 / (1+ x) = 11/12
The LCD is 12x(x + 1).
Now we multiply each term by 12x(x + 1)
2*12(x+1) + 12x = 11x(x + 1)
and this is solved in the usual way.
Answer:
False
Step-by-step explanation:
Answer:
Exterior angles (in a regular polygon) add to 360°. So you would do 360/40 to get an answer of 9. That is not the fastest solution, but your (n−2)×180∘ is the sum of the interior angles. Since the polygon is regular, each interior angle is therefore n−2n×180∘

Answer:
2 hours
Step-by-step explanation:
If Thomas can paint 1/3 = 2/6 of the room in a hour and Brian can paint 1/6 of the room in an hour. Which means in an hour they can collectively paint 3/6 = 1/2 of the room. Now you need to find how long it would take then to paint 2/2 of the room. Knowing that 1/2+1/2 = 2/2, it would take them 2 hours to paint the room together
