-2x

3x+1

10

this is what i understood from what you typed...

now, if we a "prime factoring" of each number, we get
204 =
2*2*3*17
120 = 2*
2*2*3*5
168 = 2*
2*2*3*7
now, notice the GCD for all three is that common bolded values, namely 2*2*3, or 12, so each room will house 12 participants,
now, how many rooms for all German? 204 ÷ 12, or 17 rooms.
how many rooms for all English ones? 120 ÷ 12, or 10 rooms.
how many rooms for the French ones? 168 ÷ 12, or 14 rooms.
so the total amount of rooms for all of them is
17 + 10 + 14.
Answer:
bigger angle is 117°
Step-by-step explanation:
x+x+54= 180 (when two angles are complementary it means that their sum is 180 degrees)
2x+54=180
2x= 180-54
2x=128
x=126/2
x= 63
x1= smaller angle
x1= 63
x2= bigger angle
x2= 63+54
x2=117
36, |-12|=12 and |-3|= 3. Using inverse operations, we multiply instead of dividing and get 36.
