Smallest #: x
Medium #: x + 2
Largest #: x + 4
Equation:
(x) + (x+2) + (x+4)= 108
3x + 6 = 108
3x = 102
x = 34
Largest #: x + 4
Largest #: 34 + 4
Largest #: 38
Cross multiply
2(11-x) = 1(3x+2)
Distribute
22-2x = 3x+2
Subtract 22 from both sides
-2x = 3x-20
Subtract 3x from both sides
-5x = -20
Divide both sides by -5
x=4
Answer:
let the angles be 7x , 13x , 16x
7x + 13x + 16x = 180 ( sum of angles in a triangle is 180 degree)
36x = 180
x = 180 / 36
x = 5
therefore the angles are:
7 X 5 = 35 degree
13 X 5 = 65 degree
16 x 5 = 80 degree
plz mark me as the brainliest
divide 60 by 12
60/12 = 5
multiply that by 3
5*3 = 15
so they will show 15 commercials every 60 minutes
