Writing Prompt: What can we do to protect endangered species?
It is important to protect endangered species because each animal deserves to thrive and grow happily on our planet. We can protect the animals' homes by reducing pollution by recycling and using more environmentally friendly products. People can stop hunting and killing animals for sport, or use animal skins to make products such as clothing, shoes, and bags. We can also spread the word and tell our friends and families about the importance of protecting and preserving animal habitats so that both animals and humans can live together harmoniously.

The cheetah is the (fastest) land animal in the world. Irregular comparatives and superlatives completely changes spelling and do not follow the formula of adding "-er" or "-est" at the end. They are combined with adjectives that do not change spelling. (beautiful, expensive). Examples: (much-more-most, bad-worse-worst, good-better-best) 4.

A coffee shop sells coffee in two cup sizes. A large cup of coffee cost $8, and a small cup of coffee costs $4. One day, the shop sold a total of 48 cups of coffee with total revenue of $260. How many large cups of coffee were sold that day? How many small cups of coffee were sold that day?
What we know: Large cup - $8, Small Cup $4 48 total cups served, Total Revenue is $260 Let large cup = x, and small cup = y x + y = 48 (total cups) 8x + 4y = 260 (total revenue) Solve for either x or y in the top equation. I choose to solve for y. x + y = 48 y = 48 - x Replace y in the equation "8x + 4y = 260" with the expression "48-x" Thus the equation becomes "8x + 4(48-x) = 260" Now, we solve for x. 8x + 192-4x = 260 [Distributive Property] 4x + 192 = 260 [Combine Like Terms] 4x + 192 - 192 = 260 - 192 [Inverse operation to each side to keep variable by itself] 4x = 68 [Combine Like Terms] 4x /4 = 68/4 [Inverse operation to get variable "x" by itself] x = 17 [Divide on both sides] We now know that a total of 17 Large cups were sold that day. Now we need to find the number of small cups. Let's replace x in the expression "x+ y = 48" with 17. 17 + y = 48 y + 17 - 17 = 48 - 17 [Inverse operation] y = 31 Check your work. 8 (17) + 4 (31) = 260 136 + 124 = 260 260 = 260 ====YES! Answer: 17 large cups of coffee were sold and 31 small cups of coffee were sold.
