The inequality for the given condition is x ≥ 42 inches
<u>Solution:</u>
Given that, the condition is you must be at least 42 inches tall to ride the bumper cars at an amusement park.
We have to write an inequality that represents this situation.
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =
Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥
Let "x" represent the heights of people who are allowed to ride the bumper cars
Height of people who are allowed to ride the bumper cars should be at least 42 inches
Height of people ≥ 42 inches [ since at least condition holds even at 42 value also ]
x ≥ 42 inches
Hence, the inequality for the given condition is x ≥ 42 inches
Hello,
Your answer is A) Neither of them are rich
Later on in the story (The Necklace), we read that Della lends Mathilda a diamond necklace. Well at the end of the story, the narrator states that the "diamond" necklace was nor real. It was a plaster model. This helps us prove that neither of them are rich and can't afford nice jewelry.
Best Of Luck,

1.
a. 12d² -6d
b. 6c^5 + 8c^4 -10c³
c. correct
2.
a. correct
b. correct
c. 12r^8-6r^4 + 9r^2, then multiply the rest by -1
3. correct
4. x² + 10
5. d=4, -1/3
Subtract 85 from both sides to get 12x>165
Divide both sides by 12 to get 165/12
