Answer:

A.

all true

B.

1.

16/20 = 12/x

16x = 240 (cross multiplication)

16x ÷16 = 240 ÷16 (isolate the variable)

x = 15

2.

x+4/2x = 12/16

24x = 16x + 64 (cross multiplication)

24x -16x = 64 (combine like terms)

8x = 64 (simplify)

8x÷8 = 64 ÷8 (isolate the variable)

x = 8

3.

10/15 = x/13-x

15x = 130 -10x (cross multiplication)

15x +10x = 130(combine like terms)

25x = 130 (simplify)

25x÷25 = 130÷25(isolate the variable)

x = 5.2

4.

28/x+1 = 21/12

21x+21 = 336 (cross multiplication)

21x = 336-21 (combine like terms)

21x = 315 (simplify)

21x÷21 = 315÷21 (isolate the variable)

x = 15

5.

9/6 = x/5

6x = 45 (cross multiplication)

6x÷6 = 45÷6 (isolate the variable)

x = 7.5

6.

4/x = 12/10

12x = 40 (cross multiplication)

12x÷12 = 40÷12 (isolate the variable)

x = 3.33
