Let Pi be 3.14
28.26/3.14 and square root = 3
The radius is 3.
Answer:
Measure of angle s:
Sum all angles of triangle is = 180 degrees
So,
31 + 58 + x = 180
x = 180 - 31 - 58
x = 91
Measure of angle s: 91 degrees
ST = 17.005
RT = 33.012

<h3>Answer: See the diagram below</h3>
=====================================
Explanation:
Start at "2" on the number line. If you move to the right 6 steps, each time landing on a tickmark, then you'll arrive at "3" on the number line. This means the interval from 2 to 3 is cut into 6 equal pieces.
In other words, the little tickmarks represent 1/6 of a unit
If we go back to "2" on the number line, and move to the first tickmark, then we arrive at 2 & 1/6. Then the next tickmark would be 2 & 2/6, and so on.
Note how 2/6 = 1/3
So the mixed number 2 & 2/6 = 2 & 1/3
The location of 2 & 1/3 is marked in red in the diagram below.
--------------------------------
The mixed number 1 & 5/6 will be plotted a similar way.
Start at "1" on the number line. Count out 5 spaces until you arrive at 1 & 5/6. This is marked in blue in the same diagram. A shorter way is to start at "2" and count backward 1 tickmark. This works because the "2" is really 1 & 6/6. Going backward one tickmark has that "6/6" bump down to "5/6".
Multiplication goes first 0.8x1.5=1.2
4+1.2-3= 2.2
<span>Simplifying
1.5x + -3y = 6
Solving
1.5x + -3y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
1.5x + -3y + 3y = 6 + 3y
Combine like terms: -3y + 3y = 0
1.5x + 0 = 6 + 3y
1.5x = 6 + 3y
Divide each side by '1.5'.
x = 4 + 2y
Simplifying
x = 4 + 2y</span>
