Answer:

Step-by-step explanation:
1. Well, when it comes to triangles. Mainly Pythagorean Triple, right triangles whose sides are 3,4,5 or 5,11,12
2. Keeping in mind this a Pythagorean Triple, then x=5
3. Then we can write it as Compound Inequality by combining the Statements for an Inequality of Triangle:
We can write it as

Or we can do:

and:

4. Writing in terms of x:

Answer:96
Step-by-step explanation:
A; 480/16 = 30 students per classroom
B: 192/12 =16 students per classroom
we need x such that 
which means
(480-x )* 12 should be equal to (192+x) * 16
5,760 - 12x = 3,072+16x
5,760 - 3,072 = 12x + 16x
2,688 = 28x
x = 96
Answer:
In the y=3x-4 section it should be (3,5), (6,14), (5,11)
In the y= (1/2)x + 2 section it should be (4,4) , (2,3)
I hope this works!
Step-by-step explanation:
Answer:
D. 20
Step-by-step explanation:
Since you are subtracting, you can add 4 and 1. The sum is 5. 20/4 is equal to 5 so R = 20.
To compare fractions you need a common denominator, then you can make a
comparison. You would divide the number line between 0 and 1 (or any 2
whole numbers on the number line) based on that common denominator. For
example... if you were trying to compare 3/4 and 2/8, you would find
the common denominator (in this case 8) and convert the fractions...
3/4 = 6/8
2/8 stays as 2/8
Now
you would go to the number line between 0 and 1 and divide it into 8
equal pieces. 3/4 would go over the 6th division and 2/8 would go over
the second division.
That would give you a good visual that 2/8 < 3/4
