(a) 2x + 5x + 4 = 25 <== ur equation
7x + 4 = 25
7x = 25 - 4
7x = 21
x = 21/7
x = 3
(b) first piece = 2x....= 2(3) = 6 ft <=

i cat see it
Step-by-step explanation:
Firstly, you know you have 27 (35/100)
Make this an improper fraction. 2735/100
Simplify this as much as you can. 547/20
Find how many times 20 will go into 540, and use the 7/20 as the fraction part of your mixed number.
Now, make as many whole as you can and states your remaining. 27 7/20
The standard form is 3x+4y=8
