Answer:she had $63.75 at first.
Step-by-step explanation:
Let x represent the amount of money that she had at first.
kathy spent 3 fifths of her money on a necklace. This means that the amount of money that she spent on the necklace is
3/5 × x = 3x/5
The amount of money remaining would be
x - 3x/5 = 2x/5
She used 2 thirds of the remainder on a bracelet. This means that the amount of money that she spent on the bracelet is 2/3 × 2x/5 = 4x/15
If the bracelet costs $17.00, then
4x/15 = 17
4x = 15 × 17
4x = 255
x = 225/4
x = 63.75
Answer:
71 - Maybe
Step-by-step explanation:
11 x 7 = 77
11 - (4 + 4) = 3
2 x 3 = 6
77 - 6 = 71
C=2pir
A=pir^2
45=pir^2
divide both sides by pi (aprox pi=3.141592)
14.32394785=r^2
sqrt both sides
3.784699176=r
sub
C=2pir
C=(2)(pi)(3.784699176)
aprox pi=3.141592
C=23.779961311m
The answer is (-6,2). I hope this helped you!
Answer:
If R is equal 5.1, Let x be A/A0
Then we have logx=5.1
Solving this we have x=125893
