Step-by-step explanation:
<em><u>solve:</u></em>
<u>Subtract 2 from both sides</u>
=6x+2=2x+10
=6x+2-2=2x+10-2
<em><u>Simplify</u></em><em><u>:</u></em>
<u>Subtract the </u><u>numbers</u>
=6x=2x+8
<u>Subtract 2x from both sides</u>
=6x<em>-2x</em>=2x+8<em>-2</em><em>x</em>
<u>Simplify</u><u>:</u>
<u>Combine like terms</u>
=4x=2x+8-2x
4x=8
<u>Divide both sides by the same </u><u>factor</u>
4x=8
4x÷4=x 8÷4=2
<em>ANSWER</em><em>:</em><em> </em><em> </em><em> </em><em> </em>
<em>x</em><em>=</em><em>2</em>
For each, replace x with the number in the parenthaseses
a.

b.

c.

division by 0 is not allowed so it is undefined at the point
d. because division by 0 is not allowed
Volume of a cylinder = area of base x height:
50.24 x 3 = 150.72 ft^3
7y-3°=3y+13°
7y-3y= 13°+3°
4y= 16°
y=4°
Substitute y
7(4)-3°= 25°
3(4)+13=25°
180°-25°-25°=130°
2(2x+3)°+130°=180°
4x+136°=180°
4x=44°
x=11°
