Hey there! :D
The midpoint and the outside line are symmetrical to eachother, 2(BF)= AE
Two midpoint segments equals one AE segment.
So, use the representation above and plug in the numbers.
2(23)= 5x -4
56= 5x-4
Add 4 to both sides.
60=5x
Divide by the 5.
x=12
I hope this helps!

First you have to canceled out the fours from both side 4x/4-12/4 so x=3 then you do the same thing to the 7x-18
4x-12.
4x/4-12/4. So x=3
The fours cancelled out
7x-18
7x/7-18/7. So x= 2 4/7
The sevens cancelled out
I'm going to divide number one to 6 parts

because to make the denominator to 100, you need to multiply 10 by 10 which is 100.
and because you multiply 10, you also have to multiply the numerator by 10.

Answer
Step-by-step explanation:
- The number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists
- Let x represent the number of cyclists.
- Since, the activists receive $60 per cyclist entry and $15,000 in donations, hence:
- Revenue = 60x + 15000
- Also, the cost of the race is $18 per entry, hence:
- Cost = 18x
- They need to raise at least $57,000, hence:
- Profit ≥ 57000
- Revenue - Cost ≥ 57000
- (60x + 15000) - 18x ≥ 57000
- 42x ≥ 42000
- x ≥ 1000
- Therefore the number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists
