Five times the sum of the product of 3 and j plus 2 plus the produce of 4 and j
angle abc and ghk are equal by given. you set them equal and solve like this.
6x+2=5x-27+3x+1 combine like terms
6x+2=8x-26 subtract 6x from both sides
2=2x-26 add 26 to both sides
28=2x divide both sides by 2
x=14
measure of abc would be 6x+2 or 6(14)+2 or 86 degrees
If he sold 1/5 of them then he would have 4 houses left because he sold 1 :)
11.3x + 7.2 = 86.3
11.3x + 7.2 (-7.2) = 86.3 (-7.2)
11.3x = 79.1
11.3x/11.3 = 79.1/11.3
x = 7
7 is your answer
hope this helps
