Answer:
2 583/1000
Step-by-step explanation:
<span>The total weights must add upto 50 lbs. Let x represents the number of 3 lb weights and y represents the number of 10 lb weights, we frame an equation as 3x + 10 y =50. Because there are some 10 lb weight and some 3 lb weights but we dont know the exact number.</span>
Answer:
You can rewrite this equation by using identity:
4x² - 12x + 9 = 0
2²x² - 2 × 2 × 3x + 3² = 0
(2x - 3)² = 0
*Just in case you want to know, x is equal to 3/2
Answer: Yes, she will finish before winter break is over.
Explanation:
Since we have given that
Number of days in winter break = 17
Number of pages she read in each day = 75
Number of pages in the Harry Potter series she wants to read = 759
Now, we'll use unitary method,
in 1 day , she read = 75 pages
in 17 days , she read is given by

and 759 pages is less than 1275 pages.
So, she will finish before winter break is over.
