Answer:
14 ft
Step-by-step explanation:
Let x represent the number of segments of the divided wood beam
Let y represent the total length of the wood beam.
Given that each segment measures 3.5, the equation to express this scenario is given as
y = 3.5x
Thus, to find the length of the wood beam, substitute x = 4 into the equation.
We would have:
y = 3.5(4)
y = 14
Length of the wood beam = 14 ft
Answer:
No solution.
Step-by-step explanation:
1-2k+5k<u><</u>-4+3k Combine like terms on each side wherever you can.
1+3k<u><</u>-4+3k Subtract -3k on both sides (it's less confusing when you get
<u>-3k -3k</u> rid of the variable first).
1<u><</u>-4 1 is not less than or equal to -4, so there is no solution.
I hope this helped you out!! Have a great day (*^3^)╭
