A pound of oranges cost x dollar => A pound of pears cost x+3 dollar
We have: 8x+4(x+3)=30 => 12x=30-12=18 =>x=1.5
5 pounds of pears cost: 5(x+3)=5(1.5+3)=5*4.5= 22.5 (dollar)
I got that question and the answer C
2x+10, multiply to two each term x and 5
The correct answer is 100 feet, because of the SAS Postulate
