Write the statement below as a bicondtional A water molecul

. Write the statement below as a bicondtional A water molecule is composed of exactly 2 hydrogen and 1 oxygen atom A Ifa molecule is water, then it is composed of exactly 2 hydrogen and 1 oxygen atom 8. A molecule is water if and only if k is composed of exactly 2 hydrogen and 1 oxygen C. A molecule is not water f and only if it is not composed of exacy 2 hydrogen and 1 oxygen atom D. A moleoule is water if and only if R is not oomposed of exactly 2 hydrogen and 1 oxygen 8. Write the statement below as a bicondtional When the sum of the digits of an integer is divisible by 9, the integer is divisible by 9 A Han ineger is divisible by 9, then the sum of the digits of the integer is divisible by9 B. The sum of the digits of an integer is divisible by 9and only f the integer is prime C. The sum of the digits of an integer is divisible by 9and only the integer is divisible by D. f the sum of the digits of an integer is divisible by 9, then the integer is divisible by 9 9. Let statements p, q, r, and s be as follow p: angle A and angle B are a linear pair q: angle A and angle B are supplementary angles. r angle A and angle B are adjacent angles s angle A and angle B are adjacent and supplementary angles Substitute for p, q r, or s, and write the statement below the way you wouild read it A angle A and angle B are adjacent angles if and only i angle A and angle B are a linear B. angle A and angle B are a linear pair, hen angle A and angle B are adjacent anglers C. angle A and angle B are adjacent angles, then angle A and angle B are a linear pair D. angle A and angle B are a linear pair if and only if angle A and angle B are adjacent angles 10. Let stabements p, q., and s be as foilo p: angle A and angle B are a linear pair q: angle A and angle B are supplementary angles r angle A and angle B are adacent angles. s angle A and angle B are adjacent and supplementary angles Subsitute for p,q.f.or s and wribe the statement below the way you would read Pq A angle A and angle B are supplementary if and only ifangle A and angle B are a linear B. Hangle A and angle B are a linear pair, hen angle A and angle B are supplementary angles C. angle A and angle B are supplementary, then angle A and angle B are a inear pair D. angle A and angle B are a linear pair if and only if angle A and angle B are

Solution

7. B (is is pretty atraight forward)

8.C (same as 7 , just use if and only if)

9.D (in these type of questions you have to first state p then r)

10.D (similarly like 9 juts state p than q)
