Answer:
radius = 23.2/(2*3.14) = =3.69
area = 3.14*3.69^2 =42.75
Step-by-step explanation:
Ok so (3x+50)=(6x-20) take the 6x -3x =3x
then 3x-10=50 add the 10 to 50
giving you 3x=60 dvide 60 by 3
X=20
Answer:
Step-by-step explanation:
<u>Goal</u>
- Find the equation of the line.
<u>Given</u>
- Coordinate points which are (4,3) and (6,2).
<u>Step</u><u> </u><u>1</u>
- Find the slope by using slope formula or rise over run.
Substitute the coordinate points in
<u>Step</u><u> </u><u>2</u>
- Rewrite the equation in slope-intercept form by substituting m = -0.5
Substitute m = -0.5
<u>Step</u><u> </u><u>3</u>
- Find the value of b by substituting any given coordinate points in the equation.
<em>Substituting</em><em> </em><em>both</em><em> </em><em>coordinate</em><em> </em><em>points</em><em> </em><em>still</em><em> </em><em>give</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>answer</em><em>.</em><em> </em>
<u>Step</u><u> </u><u>3.</u><u>1</u>
- Substitute (4,3) in the equation.
<u>Step</u><u> </u><u>3</u><u>.</u><u>2</u>
- Substitute (6,2) in the equation.
<u>Step</u><u> </u><u>4</u>
- Rewrite the equation again by substituting the value of b.
Substitute b = 5 in the equation.
Hence, the equation is y = -0.5x + 5
Answer:
Your first step should be to separate the x's and the numbers.
This is how I would do it:
-3x+2-5x-7=4x+2
-3x-5x-4x=2-2+7
-12x=7
x=-7/12
