Answer:
see explanation
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
Answer:

Answer:
pleasant memories can calm a person during stressful times
Explanation:
Nadia's stage fright is written by Clark Benson. Nadia is practising one song over and over to perform and give her best in the Talent Show. Her partner during practising time is her pet Lucky who sits beside Nadia on the floor.
<u>When Nadia was frightful in the 7th stanza, she calmed herself by remembering pleasant memories with Lucky. This shows that frightful or stressful emotions can be overcome by recalling pleasant memories</u>.
And this also suggests the theme of the story that pleasant memories have the power to calm a person when he/she is stressful.
So, the correct answer is the last option.
