Solve each inequality. 1.     > 10

First multiply 5 on both sides to get rid of the five on the bottom.

Subtract 1 from both sides of the inequality.

Divide -7 on both sides, and flip the inequality sign since we are dividing by a negative.

The solution to the inequality is n<-7.

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

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
