Step-by-step explanation:
by using similarity and enlargement
10/8 = 7+y/7
70=56+8y
8y=14
y= 7/4
10/8 = 5+x/5
50=40+8x
x = 8/10 = 4/5
<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r).
Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi).
If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>
Answer:
The equation is y= 0,65 x
Step-by-step explanation:
Answer:
$175
Step-by-step explanation:
Equation for Price Reduction:
Original Price * Percent Remaining of Original = New Price
Plug in the given values into the equation:
Original Price * 0.8 = $140
Divide both sides by 0.8 to isolate the Original Price:
140/0.8 = 175
Answer:
the answer is 1/3
Step-by-step explanation:
3/15 equals 1/5 so 1/5+4/5=1 so 1-2/3=1/3
