In a two-digit number, if the digit in the one's place is a 4, what must be true about the number? A. It must be divisible by 6. B. It must be divisible by 4. C. It cannot be divisible by 5. D. It cannot be divisible by 7.

C. It cannot be divisible by 5.

Step-by-step explanation:

C. Numbers divisible by 5 can only have a 0 or 5 in the one's place.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
