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
