almond37 [142]

Answer:

3 groups

Step-by-step explanation:

Sopranos = 12

Altos = 9

Find the highest common factor of 12 and 9

12 = 1, 2, 3, 4, 6, 12

9 = 1, 3, 9

The highest common factor of 12 and 9 is 3

Therefore, the choir teacher can only have 3 groups

12 sopranos / 3 groups

= 4 sopranos per group

9 Altos / 3 groups

= 3 altos per group

Each of the 3 groups Will have 4 sopranos and 3 altos each

What is 2(9x+3)+5x=48+2x

kati45 [8]

2(9x + 3) + 5x = 48 + 2x
18x + 6 + 5x = 48 + 2x
23x + 6 = 48 + 2x
23x - 2x = 48 - 6
21x = 42
x = 42/21
x = 2
