Answer:
Step-by-step explanation:
4x + 3y + x + 4y
= 4x + x + 3y + 4y
= 5x + 7y
4x + 3y + 2x - y
= 4x + 2x + 3y - y
= 6x + 2y
4x + 5y - ( x + 4y )
= 4x + 5y - x - 4y
= 4x - x + 5y - 4y
= 3x + y
2x - y + 3x + y
= 2x + 3x - y + y
= 5x + 0
= 5x

Hi there.
Your answer is correct, as you need to divide both sides by 3.5 to solve for x, which results in $14/h.
I hope this helps!
A = 1/2(b X h)
20.025 = 1/2(8.9 X u)
20.025*2/1= 1/2 * 2/1(8.9 x u)
40.05 =8.9u
40.05/8.9 = 8.9u/8.9
u = 4.50
Check
A = 1/2(b X h)
A = 1/2(8.9 X 4.5)
A = 1/2(40.05)
A = 20.025 in²
Simple, to make it less harder change 4/5 into 0.8
Making the equation,
0.8(15x-5)
Then just multiply:
take 0.8*15(x)=12x
then
0.8*-5=-4
Making the problem, simplified out, 12x-4.
