Answer:
#1
- 150*(1 - 5/8) = 150(3/8) = 56.25
- Option A
#2
- 56.80 + 22.70x = 374.60
- 22.7x = 374.60 - 56.80
- 22.7x = 317.8
- x = 317.8/22.7
- x = 14 months
#3
- Blue = 20 - (9 + 5) = 6
- p(blue) = 6/20 = 0.3 or 30%
#4
- 3 3/4 + 20% of 3 3/4 =
- 3 3/4*1.2 =
- 15/4 * 12/10 =
- 9/2 = 4.5 hr
#5
Actual value = 72 in, expected value = 68 in
- Error = 72 - 68 = 4 in
- Percent error = error/ expected value * 100% =
- 4/68*100% = 5.9% (rounded)
#6
- d + 8% = d + 0.08d = 1.08d
- d*1.08 = 1.08d
#7

- Data = 42, 43, 45, 4.7, 48
- Mean = (42+ 43+ 45+ 47+ 48) / 5 = 45
- Absolute deviation = (|42 - 45| + |43 - 45| + |45 - 45| + |47 -45| + |48 - 45|)/5 = 2
<u>Nadia</u>
- Data = 36, 37, 46, 50, 51
- Mean = (36+ 37+ 46+ 50+ 51)/5 = 44
- Absolute deviation = (|36 - 44| + |37 - 44| + |46 - 44|+ |50 -44| + |51 - 44|)/5= 6
<u>Nadia had greater mean absolute deviation:</u> 6 - 2 = 4 (seconds)
<h3>Answer: 5x-3</h3>
=======================================================
Explanation:
Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.
If we multiply 5 by whatever is in the box, we can write it like
Then let's say we fill that box with the value 7. We would then have
If we put 3 in the box instead we'll have and so on
Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.
--------------------------
So far we've shown that "5 times a number" turns into 5*x or just 5x.
From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.
The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.

Answer:
You would put 11y-22+7y-6+3x+12+5x and that will give you the answer. Hope this helps!
Volume of shipping box: 3 3/4 x 3 x 3 1/4 = 36 9/16 cubic feet.
Volume of fish food box: 1/4 x 1/4 x 1/4 = 1/64 cubic feet.
Number of fish food boxes: 36 9/16 / 1/64 = 2,340 boxes.
