Answer:
A, B, and C
Step-by-step explanation:
The answer for 15.2+w=19.75+4.2 is <u>w=8.75</u>
3w=22.25+4 is <u>w=8.75</u>
The next equation is w= -8.75
The last equation is <u>w= 8.75</u>
An absolute value inequality for "all numbers less than 7 and greater than -7" is given by |x| < 7.
<h3>How to write an absolute value inequality?</h3>
Based on the information provided, we can logically deduce that the statement describes an intersection of set because the word "and" was used.
This ultimately implies that, we would use the less than (<) symbol to write an absolute value inequality for the given statement:
|x| < 7
Therefore, this can be translated as follows:
-7 < x < 7 or x < 7 and x > -7.

<h2>
Answer: 90 rabbits</h2>
<em></em>
<h3><em>
Step-by-step explanation:</em></h3>
<em>you will need 10 for every 3 rabbits so if you count in tens and three's </em>
<em>3=10</em>
<em>6=20</em>
<em>9=30</em>
<em>and so on..</em>
<em>when you get to 27 you'll be at 90 </em>
<em>27=90 </em>
<em>hope u understand :></em>
Answer:
55 degrees (a)
Step-by-step explanation:
complementary means they equal 90 degrees
so 90-35= 55 degrees
Answer:
13 1/3 and 6 2/3.
Step-by-step explanation:
Let the 2 parts be x and (20 - x).
So x^2(20 - x) must be a maximum.
y = x^2(20 - x)
y = 20x^2 - x^3
Finding the derivative):
y' = 40x - 3x^2 = 0 for maxm/minm value.
x( 40 - 3x) = 0
40 - 3x = 0
3x = 40
x = 40/3.
This is a maximum because the second derivative y" = 40 - 6x = 40 - 6(40/3)) is negative.
So the 2 numbers are 13 1/3 and 6 2/3.
