Explanation:
(a)
3x + 5y = 8 → (1)
4x - 3y = 1 → (2)
multiplying (1) by 3 and (2) by 5 and adding the result will eliminate y
9x + 15y = 24 → (3)
20x - 15y = 5 → (4)
add (3) and (4) term by term to eliminate y
29x + 0 = 29
29x = 29 ( divide both sides by 29 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y
substituting into (1)
9(1) + 15y = 24
9 + 15y = 24 ( subtract 9 from both sides )
15y = 15 ( divide both sides by 15 )
y = 1
solution is x = 1 , y = 1
-----------------------------------------
(b)
6p + 4q = 20 → (1)
5p - 2q = 6 → (2)
multiplying (2) by 2 and adding to (1) will eliminate q
10p - 4q = 12 → (3)
add (1) and (3) term by term to eliminate q
16p + 0 = 32
16p = 32 ( divide both sides by 16 )
p = 2
substitute p = 2 into either of the 2 equations and solve for q
substituting into (1)
6(2) + 4q = 20
12 + 4q = 20 ( subtract 12 from both sides )
4q = 8 ( divide both sides by 4 )
q = 2
solution is p = 2 , q = 2
We can write the correct prepositions to complete the sentences in the following manner:
- Enthusiastic about is similar to interested in.
- Bad at is the opposite of good at.
- Stressed out = worried about.
- Keen on means you really like something.
<h3>What are prepositions?</h3>
A preposition is usually a short word employed to make a connection between or establish a relationship between ideas. Examples of prepositions are:

The answer is either the first or last one all X intercepts have a Y of zero, you did not give enough information to determine if it is negative or positive for the X value but if the X intercept is on the left side of the Y axis that means that it is the first answer if it is on the right side it is the last answer.
Answer: I read the book about dogs
the two sentences that best describe this passage are "being around pets benefits kids who need to learn responsibility." and "a study by the University of California found that reading to dogs improved third graders' reading skills."
together these two sentences sum up all of the ideas in the article and explain all of the benefits described. the second sentence sums up the majority of the article and choosing the one about improving a children's ability to learn would be repetitive. and the other about it being good for the teachers isn't mentioned in the article at all.
the study is the most important part of the passage and covers pretty much the entire beginning of it. the responsibility was kind of added in as a "hey this is a thing too" but it really showcases how beneficial the dogs are to kids and that's what the message of the article is
