Answer:
168 cents or = $1.68
Step-by-step explanation:
11 inches of wire cost 66 cents
28 inches of wire cost x? cents
x = 28 * 66 / 11 = 168 cents or = $1.68
Answer
168 cents or = $1.68
<em>20x</em>+20-4<em>-15x</em>=96-32
(next:subtract 96-32)
<em>20x</em>+20-4<em>-15x</em>=64
(next: then combine like terms)
<em>5x</em>+16=64
(next: subtract 16 from 64)
<em>5x</em>=48
(next: divide 48/5)
<em>x=9.6</em>
Answer:
x = 105
y = 64
Step-by-step explanation:
Inside the four sided figure, the angles must add to 360. So 121+70+x+y = 360. You also know that a straight line is 180. This means 116 + y = 180. Using them together you can solve for the variables. Begin by substituting the equation 116 + y = 180 into the other equation.
116 + y = 180 converts to y = 180-116 = 64.
Substitute y = 64 into 121 + 70 + x + y = 360.
191 + x + 64 = 360
255 + x = 360
x = 105
