Sagot :
Answer:
x = 9, FG = 8
Step-by-step explanation:
The question depends on the relationship EF + FG = EG (the two shorter segments add up to the long segment).
7 + 2(x - 5) = 3(x - 4)
7 + 2x - 10 = 3x - 12
-3 + 2x = 3x - 12
-3 = x - 12
9 = x
The length FG can be found by substituting 9 for x.
FG = 2(x - 5) = 2(9 - 5) = 2(4) = 8
Answer:
x should be 8 and FG should be 7
Step-by-step explanation:
Considering segment EF and FG look relatively the same in length, let's assume 2(x-5) = 7.
And assuming both segments are equal to 7, the total would be 14.
3x-12=14
add 12 to 14 which would get you 26
3x=26
divide 26 by 3
which would be 8.666 repeating which for the sake of this we'll round down to 8
check with 2(x-5)
2x-10=7
add 10 to 7
17/2 should equal 8.5 which we'll round down to 8
take this with a grain of salt as I don't know much about college math
