Answer:

Step-by-step explanation:

Two angles (1) and (2) are supplementary Means m∠(1) + m∠(2) = 180

then

(7x+2) + (3x-2) = 180

then

10x = 180

then

x = 18

Step-by-step explanation:

since the two angles are supplementary angles they add up to give 180°

therefore, 7x+2+3x-2=180°

or, 10x= 180°

or, x= 18°

Desiree writes songs for her band her first song is 3 1/2 minutes long her second song is one 1/2 times as long as her first son

vesna_86 [32]

Answer:Number of minutes of second Song = 5 1/4 minutes

Number of minutes of third Song =3 1/2 minutes

Step-by-step explanation:

Number of minutes of First Song = 3 1/2 minutes

Number of minutes of second Song = one 1/2 times as long as her first

= 1 1/2 X 3 1/2 minutes

3/2 X 7/2

21/4 = 5 1/4 minutes

Number of minutes of third Song = 2/3 times as long as her second song

2/ 3 x 5 1/4

= 2/3 x 21/4 =42/12

Dividing the numerator and denominator by 3 to reduce the fraction

42/ 12 / 3/3 = 14/4

14/4 = 3 2/4 = 3 1/2 minutes
