Answer:
3
Explanation:
(1/3x-1/6y)×18=4×18 ⇒ 6x-3y=72
6x-ay=8 if a=3 ⇒ 6x-3y=8
72≠8
a=3 ⇒ system has no solution
Inequalities are used to represent unequal expressions.
The solution set to 
is: 
The inequality is given as:
From the inequality above, we have the following observation.
- The value of variable x starts from 7/16 (inclusive)
- The value of variable x has no end (i.e. infinity)
Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [
We treat 
, as an exclusive value. So, we make use of the close parenthesis i.e. )
Hence, the solution set is:

The brain is the body's control centre: it sends messages to your body through a network of nerves called “the nervous system”, which controls your muscles, so that you can walk, run and move around.
Answer:
It's wrong.
Explanation:
In the Punnett square, we will use F to represent the dominant freckles gene and f to represent the recessive lack-of-freckles gene. The first individual would have FF, because homozygous means that both alleles are the same. The second individual would have Ff, because heterozygous means that it has 2 different alleles. If the first individual passes down one of its "F" alleles and the second individual passes down its "F" allele, the offspring would have 2 dominant alleles, and the researcher's conclusion is disproven.
