Fun
n=number of nickles
q=number of quarters
d=number of dimes
4 more dmes than nickles, 3 more quarters than dimes
d+4=n
q=3+d
total value is 455 cents
10d+5n+25q=455
divide both sides by 5 to simplify
2d+n+5q=91
now we convert all to one coin
q=3+d and n+4=d
subsitute 3+d for q and n+4 for d
2(n+4)+n+5(3+d)=91
2(n+4)+n+5(3+n+4)=91
2(n+4)+n+5(n+7)=91
2n+8+n+5n+35=91
8n+43=91
minus 43 both sides
8n=48
divide both sides by 8
n=6
sub back
n+4=d
6+4=d
10=d
q=3+d
q=3+10
q=13
6 nickles
10 dimes
13 quarters
10(4x-1) is the answer to your question my friend
Answer:
−(2x)/(5)−9
Step-by-step explanation:
Replace the function designators in g−1x
with the actual functions.
(3/5x−9)−1x
Simplify (3/5x−9)−1x
−(2x)/(5)−9
Answer: B
Step-by-step explanation: I took the quiz and got it right
Also, if you graph the equations on a graphing calculator, the lines are right on top of each other, so the first equation can't be less than -1, so no solutions
Most of the information's required for finding the answer is already given in the question.
Height of the fly = 12 feet
Width of the fly = 16 feet
Now we can find the length of the poles using Pythagoras theorem.
Length of the poles = square root [(12)^2 + (8)^2]
= square root (144 + 64)
= square root (208)
= 14.4 feet
From the above deduction, we can conclude that the height of the poles needed to be 14.4 feet. I hope the answer has helped you.
