I’m pretty sure it’s B because you can put in any number and it could still have a difference of 1
Answer:
±5
Step-by-step explanation:
The double bar around <em>n</em> is absolute value. This means that any number plugged in will turn positive.
Therefore, there are only 2 numbers that can be inputted: -5 and 5.
|-5| = 5
|5| = 5
Answer:
230 were sold at the door
170 were sold in advance
Step-by-step explanation:
x=at door y=in advance
x+y=400
3x+2y=1030
y=-x+400
2y=-3x+1030
y=-3/2x+515
-x+400=-3/2x+515
x=230 y=170
First you need to find the area of the lawn. To find the area of a square, you multiply two sides together. You have two sides given, which is super helpful.
I put in my calculator, (40+4/5)x(50+7/8) and this gave me the answer of 2075.7.
You need to then divide that number by 500, and divide it by 300, and then round up, cause if you round down you’re not gonna have enough seed.
2075.7/500 = 4.1514, but then this needs to be rounded up or he’ll be 0.1514 short. So he needs 5 bags for the highest setting.
2075.7/300 = 6.919, so for the lowest setting, he needs 7 bags of seed.
This should be correct.
Hope this helps :)
