<em>Answer:</em>
<em> $ 34, 34</em>
<em>Step-by-step explanation:</em>
<em>1800 mm = 1, 8 m</em>
<em>1200 mm = 1, 2 m</em>
<em>A = 1,2 × 1,8 = 2, 16 m²</em>
<em />
<em>1 m² ..................... $ 15.90</em>
<em>2, 16 m² .............. $ x</em>
<em>x = 2,16×15,90/1 ≈ $ 34, 34</em>
And that equals 9.5 you always put a .5 next to 9 or any other number. Or, if you're doing a question that has to equal a number of candy in every bag, or something else, you add the remainder as the number 1 with 9. So 1+9 =10 either one of those:)

Answer:
Here,
denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far
Step-by-step explanation:
Number of cookies made by Walter so far = 15
He is asked by his coach to make at least 20 cookies but no more than 55.
Let
denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far.
The inequality is ![20\leq x+15\leq 55](https://tex.z-dn.net/?f=20%5Cleq%20x%2B15%5Cleq%2055)
Now solve this inequality.
![20\leq x+15\leq 55\\20-15\leq x\leq 55-15\\5\leq x\leq 40](https://tex.z-dn.net/?f=20%5Cleq%20x%2B15%5Cleq%2055%5C%5C20-15%5Cleq%20x%5Cleq%2055-15%5C%5C5%5Cleq%20x%5Cleq%2040)
