Lily has saved $ 7
<em><u>Solution:</u></em>
Given that bracelet costs $30
The bracelet Lily would like to buy costs $5 less than 5 times the amount she has saved
Cost of bracelet = $ 30
From given statement,
Cost of bracelet = 5 times the amount she has saved - 5
Let "x" be the amount saved by lily
Cost of bracelet = 5 times x - 5
Here "times" represents multiplication
30 = 5(x) - 5
30 = 5x - 5
30 + 5 = 5x
5x = 35
On dividing 35 by 5 we get 7
x = 7
Thus Lily saved $ 7

the formula to calculate the distance between two points is equal to
substitute the values
The radius is half the diameter
so
step 2
Find the center of the circle
the center of the circle is the midpoint between the endpoints of the diameter
so
The center is
step 3
Find the equation of the circle
The equation of the circle is
substitute the values
-2x^4+x^2-x-9+x^4-x^3-5x+3
-x^4-x^3+x^2-6x-6
