Answer:
2 < x < 5
Step-by-step explanation:
<u>< This symbol means 'less than'</u>. The number you put on its left side is less than the number on its right side.
<u>> This symbol means 'greater than'</u>. The number put on its left is greater than its number on the right.
Think of them like a mouth. Remember the 'open side' wants to eat more.
Translate words to symbols:
'x is less than 5'
x < 5
'x is greater than 2'
x > 2
Put them together. The < and > symbols change directions, but x on the closed side of 5. Keep x on the open side of 2.
2 < x < 5
Don't confuse < and > with ≤ and ≥.
≤ and ≥ mean 'less than OR equal to' and greater than OR equation to'.
Answer:
91
Step-by-step explanation:
Let
x = first number
x+1 = second number
x+2 = third number
x+3 = fourth number
Total = 182
x + x + 1 + x + 2 + x + 3 = 182
4x + 6 = 182
Subtract 6 from both sides
4x + 6 - 6 = 182 - 6
4x = 176
Divide both sides by 4
x = 176 / 4
= 44
x = 44
x = 44
x+1 = 44 + 1 = 45
x+2 = 44 + 2 = 46
x+3 = 44 + 3 = 47
Sum of the two middle numbers = 45 + 46
= 91
Given:
The point is (-8,3).
To find:
The image of the given point after a rotation of 270 degrees counterclockwise about the origin.
Solution:
If a point is rotated 270 degrees counterclockwise about the origin, then the rule of rotation is:
Using this rule, we get
Therefore, the image of the given point after a rotation of 270 degrees counterclockwise about the origin is (3,8).
Answer:
<em>Answer: 12 milliliters</em>
Step-by-step explanation:
<u>Proportions</u>
Each vial contains 250 milligrams of aminophylline in 10 milliliters. This means the concentration of aminophylline in the vials is 250/10 = 25 milligrams/milliliter.
To administer 300 milligrams of aminophylline, we need to find the number of milliliters according to the concentration calculated above.
If each milliliter adds up to 25 milligrams, then to have 300 milligrams, 300/25 = 12 milliliters of aminophylline vials are needed.
Answer: 12 milliliters
