A) multiply equation A by -2 so you get -2x - 2z = -12 and then you can add both equations to eliminate z

After reading the story “First Day of School,” pick up where the story left off and add a climax, falling action and resolution.
Anit [1.1K]

Although this question asks for original work, and therefore, only you can complete it, we can provide an example to help you guide your work:

<em>"My sister and I said goodbye to mom, and we were ready to finally approach the school and begin one of the most important days of our lives. We were nervous, and worried about whether this year was going to be a good one. I turned around to my sister and asked:</em>

<em>- Are you ready?</em>

<em>- I'm so not ready...</em>

<em>We approached the school, and as we pulled the door, the most delicious smell hit us. It smelled like sweetness, and like a day in the park. We walked in, and what we saw left us in awe.</em>

<em>The school had organized a festival! In order to make the first day of school easier, the morning classes had been cancelled, and we were instead allowed to run and play for a few hours, in order to get to know each other. I saw donuts, corndogs and ice cream. I also saw many kids running around. My sister could not believe her eyes.</em>

<em>- This is the best day ever! - she yelled, while she ran to grab a donut."</em>

In this addition, the conflict is an internal one, as the children feel worried about school. However, this is resolved by the festival that was organized. The climax occurs when the children notice the festival, while the falling action and resolution occur when the children are able to relax and their worries about school disappear.

To solve this problem, we need to use the Pythagorean Theorem, which states that a^2 + b^2 must equal c^2. "a" is the length of one of the legs (shorter sides of the triangle) and "b" is the length of the other leg. "c" is the length of the hypotenuse.

a = y = 36.25cm

b = x = 20.93cm

a^2 + b^2 = c^2

(36.25)^2 + (20.93)^2 = c^2

1314.0625 + 438.0649 = c^2

√1752.1274 = √c^2

c = 41.8584209 ≈ 41.86

So your final answer is...

The length of the hypotenuse is about 41.86 cm.

Well 40 divided by 5 is 8 and you don't have options so I would say 8 loads a day :)
