Answer:
9 ft
Step-by-step explanation:
Let x represent the shortest piece. Then the sum of lengths is ...
x + (x +25) +3x = 40
5x = 15
x = 3
3x = 9
The third piece is 9 feet long.
_____
<em>Check</em>
The pieces are 3 ft, 28 ft, 9 ft, so total 40 ft, as required.
Answer:
x = 2
Step-by-step explanation:
x/(x+1) = (x+6) / (x+10)
the 10 comes from 9+1
Then cross multiply and solve for x
the terms cancel out just leaving behind a nice linear function.
Answer:
2x^31
Step-by-step explanation:
~Simplify the expression
2x^29/x^-2
~Apply quotient rule [ a^b/a^c = a^b-c ]
2x^31
Best of Luck~
Answer:
y=-2/5x + 3 is the eq of the line
Answer:
150 squared yards
Step-by-step explanation:
To get the area of something you need to multiple the width and the length of that something.
The scale for he game room is 1 ft: 5 yd.
