Write an expression equivalent to 1/5 x + 10.

Simplifying 4x + -3y = 1 Solving 4x + -3y = 1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3y' to each side of the equation. 4x + -3y + 3y = 1 + 3y Combine like terms: -3y + 3y = 0 4x + 0 = 1 + 3y 4x = 1 + 3y Divide each side by '4'. x = 0.25 + 0.75y Simplifying x = 0.25 + 0.75y

Step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
