A, 2. 35 times 55 represents the area, and that equals 1925. Subtract the 1250 from one bag from the 1925 you need to cover the area (do 1925-1250) to find how much more you need after using one bag. That gets you 675, so you'll need one more bag to cover that for 2 bags in total. The second bag will put you over the 675 you need, but that's ok because now you have enough to cover the 1925 sq foot area.
Answer:
11.5 meters
Step-by-step explanation:
If B is midpoint of AC, then BC is half of AC.
BC= AC/2
=23/2
=11.5 meters

Answer:
No.
Step-by-step explanation:
Take the second expression: 5(2 - 20)
To solve, you must distribute the 5 to all terms within the parenthesis:
5(2 - 20) = (5 * 2) - (5 * 20) = 10 - 100 = -90
On the other hand:
10 - 20 = -30
∴ the two expressions are not equivalent.
Answer:
y = (-x - 6)/2
Step-by-step explanation:
x + 2y = -6
2y = -x - 6
y = (-x - 6)/2
