One number is five less than a second number. Six times the first is 10 more than 2 times the second. Find the numbers.

5 and 10

Step-by-step explanation:

let the first be a and second b

a+5=b first equation

6a=10+2b second equation

a=b-5 from the first equation

put a=b-5 into the second

6(b-5)=10+2b

6b-30=10+2b

collect the like terms

4b=40

b=10

a=b-5

a=10-5=5

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
