Y^2-4
Explanation:
Divide y^3 by y. Subtract the exponents to get y^2. Divide 4 by -1 and you get -4.
Answer:The original price of the skirt was $16
Step-by-step explanation:18+16=34
Okay. So, there will be 12 small turbines, with 3 blades on each of them. 12 * 3 is 36. Marco will need 36 wind turbine blades total. 4 of them cost $79.64. 36/4 = 9. We would multiply 79.64 by 9 to get the cost for all blades. 79.64 * 9 is 716.76. The total cost for 36 blades would be $716.76.
Answer:
x must be 14/4 = 7/2
Step-by-step explanation:
The sum of the three interior angles of a triangle must be 180 degrees.
Thus, in this particular case,
82 + 64 + 4x + 20 = 180, or
146 + 4x = 160, or
4x = 160 - 146 = 14
Then 4x = 14, and x must be 14/4 = 7/2
You have to put the equations into slope intercept form/y=mx+b.
