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'.
The area of a circle is <u>(pi) x (the circle's radius)</u>²
The circle's radius is (1/2) of (its diameter).
Area = (pi) x (12/2 inches)² =
(pi) x (6 inches)² =
(3.14) x (36 square inches) = <em>113 square inches</em> (rounded)
Answer:
N is M reflected across the x-axis; only the signs of the x-coordinates of M and N are different.
Step-by-step explanation:
The y-axis is vertical, and the x-axis is horizontal. If a point, or image, is reflected over the x-axis, in this case M and N, then the signs of the y-coordinates do not change, and instead the coordinates of the x-axis change.
If I understand your question right, this is not necessary, but is very useful to keep problems organized.
Answer:
85 degrees
Step-by-step explanation:
180=x+4x-20
180=5x-20
200=5x
x=40
C=2(40)+5
C=80+5
C=85
