Question

Please help me with my homework​

Answer 1

Explanation:

19: C

20: C

21: if WXY = 62 => since WXY = WXZ + ZWY

62 = 7x + 2 + 3x

62 = 10x + 2

62 - 2 = 10x

60 = 10x

60 : 10 = x

6 = x (A)

22: WXZ = 7x + 2 => WXZ = 7 * 6 + 2 = 42 + 2 = 44 => WXZ = 44 (B)

23:ZWY = 3x => ZWY = 3 * 6 = 18 => ZWY = 18 (A)

hope I helped you :)
