Answer:
x= 3/4 or 0.75
Step-by-step explanation:
multiply by 7
-7x+3= 14x-25
3=21x-25
28=21x
x=3/4
Answer:
15
Step-by-step explanation:
Given that the profit equation from selling x necklaces is
P = −x2 + 35x.
To make a profit of $300, the profit P = 300 then
300 = -x2 + 35x
x2 - 35x + 300 = 0
solve by factorization
x2 - 15x - 20x + 300 = 0
x(x - 15) - 20(x - 15) = 0
(x - 15)(x - 20) = 0
x - 15 = 0 or x - 20 = 0
x = 15 or 20
Since 20 is higher, the least number of her necklaces she must sell to make a profit of $300.00 is 15

A=P(1+r/n)^(nt) where n= number of times compounded yearly, t= time and p= principle
A=723(1+.029/2)^(2*23)
A=$1,401.95 So C
Variables: x, y, z (we should multiply them and put them together )
Then coeffitions, we should multiply them
Now put coeffitions before variables:
