Hi! for x, you need to do 2x-8 = x+17 and solve, because since b is the midpoint, ab and bc would be congruent.
2x-8 = x+17
1x-8 = 17
1x = 25
x = 25
in order to find ab, you plug in the x into the expression.
ab = 2x-8
ab = 2(25)-8
ab = 42
do the same for bc:
bc = x + 17
bc = 25 + 17
bc = 42
and for ac, combine the two expressions and plug in the value for x.
ac = ab + bc
ac = 2x-8 + x+17
ac = 2(25)-8 + 25+17
ac = 84
i hope this helped! have a good day/night :)

Answer:
Calico Crayfish has the largest range ⇒ The range = 9
Step-by-step explanation:
∵ The rang is the difference between the largest value
and the smallest value
In the Calico Crayfish the largest value is 10 and the smallest value is 1
∴ The range = 10 - 1 = 9
In the Zebra Mussel the largest value is 10 and the smallest value is 2
∴ The range = 10 - 2 = 8
In the Blue-back Herring the largest value is 10 and the smallest value is 4
∴ The range = 10 - 4 = 6
In the Shield Darter the largest value is 9 and the smallest value is 2
∴ The range = 9 - 2 = 7
∴ The largest range is 9 in Calico Crayfish
Answer:
45 minutes
Step-by-step explanation:
75% is the same as 
. This means that we can multiply 60 by to find 75% of 60.
The square root of 78 is an irrational number, so the exact number
can't be written down, no matter how long you make the decimal.
If I say it's 8.8318, then my answer is too big, but only by about 0.0004 percent.
